    *The Date of Deposit. The Indenture was signed and the initial deposit of
Securities with the Trustee was made on the Date of Deposit.
   **Based on the evaluation of the Securities as of 4:00 P.M. on March 29,
1996.
  ***The sales charge consists of an Initial Sales Charge and a Deferred Sales
Charge. The Initial Sales Charge is computed by deducting the Deferred Sales
Charge ($20.00 per 100 Units) from the aggregate sales charge (a maximum of
2.90% of the Public Offering Price); thus on the date of this Summary of
Essential Information, the Initial Sales Charge is $8.32 per 100 Units or 0.85%
of the Public Offering Price. The Initial Sales Charge paid by a Unit Holder may
be more or less than $8.32 per 100 Units based on the fluctuation of the value
of the Securities on the date of purchase. The Initial Sales Charge is reduced
on a graduated basis on purchases of $25,000 or more (see "Public Offering of
Units--Volume Discount"). The Deferred Sales Charge is paid through reduction of
Trust assets by $2.00 per 100 Units on each Deferred Sales Charge Payment Date
through the sale of Securities on each such date or distribution of cash
available in the Principal Account for such payment. On a repurchase, redemption
or exchange of Units before the last Deferred Sales Charge Payment Date, any
remaining Deferred Sales Charge payments will be deducted from the proceeds.
Units purchased pursuant to the Reinvestment Program are subject to that portion
of the Deferred Sales Charge remaining at the time of reinvestment (see
"Reinvestment Program").
 ****This price is computed as of the Date of Deposit and may vary from such
price on the date of this Prospectus or any subsequent date.
 *****This price is computed as of the Date of Deposit and may vary from such
price on the date of this Prospectus or any subsequent date. Reflects deductions
for remaining Deferred Sales Charge payments ($20.00 per 100 Units initially).
In addition, after the initial offering period, the repurchase and cash
redemption prices will be further reduced to reflect the Trust's estimated costs
of liquidating Securities to meet the redemption, currently estimated at $1.15
per 100 Units.
******See: "Expenses and Charges" herein. The fee and the expenses accrue daily
and are payable on each Distribution Date. Estimated dividends from the
Securities, based on the last dividends actually paid, are expected by the
Sponsor to be sufficient to pay the estimated expenses of the Trust. In addition
to the Trustee's fee, brokerage costs borne by the Trust in connection with the
purchase of Securities by the Trustee with cash deposited in the Trust are
currently estimated at $0.90 per 100 Units.
    +The number of Units will be increased as the Sponsor deposits additional
Securities into the Trust. See "Introduction", in Part B.
   ++The final distribution will be made within 5 business days following the
receipt of proceeds from the sale of all Portfolio Securities. (See:
"Administration of the Trust--Termination".)
  +++The cost of preparation and printing of the Indenture, Certificates,
Registration Statement and other documents relating to the Trust, Federal and
State registration fees and costs, initial fees of the Trustee, and legal and
auditing expenses will be paid by the Trust and, therefore, will be borne by
Unit Holders as is common for mutual funds. The organizational expenses will be
amortized over the life of the Trust.
 ++++The Sponsor may offer a program which permits a lower minimum purchase.

The  Example assumes reinvestment  of all dividends  and distributions and  utilizes a 5%  annual rate of
return as mandated  by Securities and  Exchange Commission  regulations applicable to  mutual funds.  For
purposes  of the Example, the Deferred Sales Charge imposed on reinvestment of dividends is not reflected
until the year  following payment  of the  dividend; the  cumulative expenses  would be  higher if  sales
charges on reinvested dividends were reflected in the year of reinvestment. Because the reductions to the
repurchase  and cash  redemption prices  described in  footnote (*****)  on page  (ii) apply  only to the
secondary market, these reductions have not been reflected  in the figures above. The Example should  not
be considered a represention of past or future expenses or annual rate of return; the actual expenses and
annual rate of return may be more or less than those assumed for purposes of the Example.

- ------------------------
(a)  The  Initial Sales Charge is actually  the difference between 2.90% and the
     Deferred Sales Charge ($20.00 per 100 Units) and would exceed 0.90% if  the
     Public Offering Price exceeds $1,000 per 100 Units.
 
(b)  The  actual fee is $2.00 per month  per 100 Units, irrespective of purchase
     or  redemption  price,  paid  in  each  of  the  last  10  months  of  each
     approximately  one-year Trust. If a Holder  sells Units before all of these
     payments have been made, the balance  of the Deferred Sales Charge will  be
     paid  from the sales proceeds.  If the Unit purchase  price exceeds $10 per
     Unit, the  Deferred Sales  Charge will  be  less than  2.00%; if  the  Unit
     purchase  price is less than  $10 per Unit, the  Deferred Sales Charge will
     exceed 2.00%.
 
(c)  Reinvested dividends  will be  subject only  to the  Deferred Sales  Charge
     remaining  at the time of reinvestment which may be more or less than 2.00%
     of the Public Offering Price at the time of reinvestment (see "Reinvestment
     Program").
 
(d)  The cost  of  preparation  and printing  of  the  Indenture,  Certificates,
     Registration  Statement and other documents  relating to the Trust, Federal
     and State registration  fees and costs,  initial fees of  the Trustee,  and
     legal  and auditing expenses will be paid by the Trust and, therefore, will
     be borne by Unit Holders as is common for mutual funds.
 
(e)  Although each Trust  has a term  of approximately  one year and  is a  unit
     investment  trust rather than a mutual  fund, this information is presented
     to permit a comparison of fees and expenses, assuming the principal  amount
     and  distributions are exchanged each year into a new Trust subject only to
     the Deferred Sales Charge.

                 SUMMARY OF ESSENTIAL INFORMATION--(continued)
 
   
    THE  TRUST--The  Dean  Witter  Select  Equity  Trust  Select  10  Industrial
Portfolio   96-2  (the  "Trust")   is  a  unit   investment  trust  composed  of
publicly-traded  common  stocks  or  contracts  to  purchase  such  stocks  (the
"Securities").   The  objectives  of  the  Trust   are  to  provide  income  and
above-average growth potential through  investment in the  ten common stocks  in
the  Dow Jones Industrial Average having the highest dividend yield (the "Select
10") as of the Date of Deposit. The companies represented in the Trust are  some
of  the most  well-known and highly  capitalized companies in  America. Many are
household names. A hypothetical investment in approximately equal values of  the
ten  highest yielding stocks in the Dow Jones Industrial Average for a period of
one year would have, in most of the last 20 years, yielded a higher total return
than an investment  in all  of the stocks  comprising the  Dow Jones  Industrial
Average  itself. The  Select 10 Industrial  Portfolio seeks to  achieve a better
performance than the  Dow Jones Industrial  Average. Investment in  a number  of
companies  having high dividends relative to their stock prices (usually because
their stock prices are depressed) is designed to increase the Trust's  potential
for higher returns. The Securities may appreciate or depreciate in value (or pay
dividends)  depending  on  the  full range  of  economic  and  market influences
affecting corporate profitability,  the financial condition  of issuers and  the
prices  of  equity  securities  in general  and  the  Securities  in particular.
Therefore, there  is no  guarantee that  the  objectives of  the Trust  will  be
achieved.  On the initial Date of Deposit and thereafter, the Sponsor may, under
the  Indenture  and  Agreement,  deposit  additional  Securities,  contracts  to
purchase  additional Securities together with a letter of credit and/or cash (or
a letter of  credit in lieu  of cash) with  instructions to purchase  additional
Securities  in order to create Additional  Units while maintaining to the extent
practicable the proportionate relationship between the number of shares of  each
Security in the Portfolio.
    
 
   
    TERMINATION--The Trust will terminate approximately 1 year after the initial
Date of Deposit regardless of market conditions at that time. After this period,
the  Trust will  liquidate. Unit  Holders of  2,500 units  or more  may elect to
receive shares in-kind.  Prior to  termination of  the Trust,  the Trustee  will
begin  to sell the Securities held  in the Trust over a  period not to exceed 10
consecutive business days (the "Liquidation Period"). Monies held upon such sale
of Securities will be held  uninvested in non-interest bearing accounts  created
by  the Indenture until distributed pro rata to Unit Holders on or about May 30,
1997 and will be of benefit to  the Trustee during such period. During the  life
of  the  Trust,  Securities  will  not  be  sold  to  take  advantage  of market
fluctuations. Because the Trust  is not managed and  the Securities can only  be
sold  during the Liquidation Period or under certain other limited circumstances
described herein, the proceeds received from the sale of Securities may be  less
than  could  be  obtained if  the  sale had  taken  place at  a  different time.
Depending on the  volume of Securities  sold and  the prices of  and demand  for
Securities  at the time of such sale, the sales of Securities from the Trust may
tend to depress the market prices of such Securities and hence the value of  the
Units, thus reducing termination proceeds available to Unit Holders. In order to
mitigate  potential adverse  price consequences of  heavy volume  trading in the
Securities taking place over a  short period of time  and to provide an  average
market price for the Securities, the Trustee will follow procedures set forth in
the  Indenture to sell the Securities in an orderly fashion over a period not to
exceed the Liquidation Period. The Sponsor can give no assurance, however,  that
such  procedures will mitigate  negative price consequences  or provide a better
price for such Securities. The Trust may terminate earlier than on the Mandatory
Termination Date  if the  value of  the  Trust is  less than  the  Discretionary
Liquidation Amount set forth under "Administration of the Trust--Termination."
    
 
   
    DISTRIBUTION--The  Trustee will  distribute any  dividends and  any proceeds
from the disposition of Securities not used for redemption of Units received  by
the  Trust on July 15, 1996, October 15,  1996, January 15, 1997 and on or about
May 30, 1997 to holders of record on  July 1, 1996, October 1, 1996, January  1,
1997  and the Termination Date, respectively. Upon termination of the Trust, the
Trustee will distribute to each Unit Holder of record its pro rata share of  the
Trust's assets, less expenses and less any Deferred Sales Charge then payable or
Unit Holders can elect to reinvest their distributions automatically in Units of
a  New Series (as defined below), if offered by the Sponsor, which units will be
subject only to  a deferred sales  charge (see "Administration  of the Trust  --
Termination").  The sale of Securities  in the Trust during  the period prior to
termination and upon termination may result in a
    
 
                                       v
<PAGE>
lower amount than might otherwise be realized if such sale were not required  at
such  time due to impending or actual termination of the Trust. For this reason,
among others, the amount realized by a Unit Holder upon termination may be  less
than  the  amount  paid  by  such  Unit  Holder.  (See:  "Administration  of the
Trust--Distribution".)
 
    The Sponsor anticipates that, based upon the last dividends actually paid by
the companies listed in the  "Schedule of Portfolio Securities", dividends  from
the  Securities will  be sufficient to  (i) pay  expenses of the  Trust and (ii)
after such payment, to make distributions  to Unit Holders as described  herein.
(See: "Expenses and Charges" and "Administration of the Trust-- Distribution".)
 
   
    PUBLIC  OFFERING PRICE--The Public Offering Price  per 100 Units is computed
on the basis of the aggregate  value of the underlying Securities next  computed
after receipt of a purchase order plus cash on hand in the Trust, divided by the
number  of Units outstanding  times 100, plus  a sales charge  of 2.925% of such
evaluation per 100 Units (the amount invested in Securities); this results in  a
sales  charge of 2.90%  of the Public  Offering Price. A  proportionate share of
amounts, if any,  in the Income  Account is  also added to  the Public  Offering
Price.  (See "Public Offering of Units--Public Offering Price".) The total sales
charge consists of  an Initial  Sales Charge and  a Deferred  Sales Charge,  the
total of which equals 2.90% of the Public Offering Price or 2.925% of the amount
invested  in Securities. The  Initial Sales Charge is  computed by deducting the
Deferred Sales Charge ($20.00  per 100 Units) from  the aggregate sales  charge;
thus,  on the date  of the Summary  of Essential Information,  the Initial Sales
Charge is $8.32 per 100 Units or 0.85% of the Public Offering Price. The Initial
Sales Charge paid by a Unit Holder may be more or less than $8.32 per 100  Units
based on the fluctuation of the value of the Securities on the date of purchase.
The  Initial Sales Charge will  vary with changes in  the aggregate sales charge
and is deducted from the  purchase price of a Unit  at the time of purchase  and
paid  to the Sponsor.  The Initial Sales  Charge will be  reduced on a graduated
basis on purchases of $25,000 or  more. Unit Holders acquiring Units through  an
exchange  or rollover of units of a  previous series of the Select 10 Industrial
Portfolio will acquire such Units subject only to the Deferred Sales Charge. The
Deferred Sales Charge is paid through reduction of Trust assets by $2.00 per 100
Units monthly on each Deferred Sales Charge Payment Date commencing on the first
Deferred Sales Charge Payment Date shown on the Summary of Essential Information
through the  sale  of Securities  on  each such  date  or distribution  of  cash
available for such payment. Units purchased pursuant to the Reinvestment Program
are  subject  only to  remaining deductions  of the  Deferred Sales  Charge (see
"Reinvestment Program"). If a Unit Holder exchanges, redeems or sells his  Units
to  the Sponsor prior to  the last Deferred Sales  Charge Payment Date, the Unit
Holder is obligated to pay any remaining Deferred Sales Charge.
    
 
   
    MARKET FOR UNITS--The  Sponsor, though not  obligated to do  so, intends  to
maintain a market for the Units. If such market is not maintained, a Unit Holder
will  be able to dispose of his Units  through redemption at prices based on the
aggregate value  of  the  underlying  Securities.  (See:  "Redemption".)  Market
conditions  may cause such prices to be greater or less than the amount paid for
Units. The Sponsor's Repurchase Price,  like the Redemption Price, will  reflect
the  deduction from the value of the  underlying Securities of any unpaid amount
of the Deferred  Sales Charge.  Investors should  note that  the Deferred  Sales
Charge  of $2.00 per  100 Units will be  deducted from Trust  assets on the last
business day of each month commencing on the first Deferred Sales Charge Payment
Date shown on the Summary of Essential Information, and to the extent the entire
Deferred Sales Charge has not been so deducted or paid at the time of repurchase
or redemption of the Units, the remainder will be deducted from the proceeds  of
sale or redemption or in calculating an in-kind redemption.
    
 
    RISK  FACTORS--SPECIAL CONSIDERATIONS--An  investment in Units  of the Trust
should be made with an understanding of  the risks inherent in an investment  in
common  stocks, including risks associated with the limited rights of holders of
common stock to  receive payments from  issuers of such  stock; such rights  are
inferior  to those  of creditors  and holders  of debt  obligations or preferred
stock. Also, holders of  common stock have the  right to receive dividends  only
when,  as and if such dividends are declared by the issuer's board of directors.
Investors should also be  aware that the value  of the underlying Securities  in
the Portfolio may
 
                                       vi
<PAGE>
fluctuate  in accordance with changes in the  value of common stocks in general.
Although there are certain risks of price volatility associated with  investment
in  common stocks, your risk is reduced because your capital is divided among 10
stocks from several different industry groups.
 
    The portfolio of the Trust is concentrated in Securities issued by companies
deriving a substantial portion of their income from the sale of oil and  related
products.  In addition to the general risks associated with investment in common
stocks, investment in the oil industry  may pose additional risks including  the
impact  of the following on the value of Securities of oil companies: changes in
demand  for  oil  products,  increased   competition  among  oil  companies,   a
substantial increase in the price of oil, a drop in production of oil, a decline
in  the supply of oil,  price controls on oil and  oil products, an oil embargo,
the  political  situation  in  oil-producing  countries,  domestic  and  foreign
government  taxes  or  controls  on  the  oil  industry,  domestic  and  foreign
environmental regulations  affecting  the  oil industries'  ability  to  operate
necessitating substantial expenditures by the oil companies, the cost of cleanup
and  litigation  costs relating  to oil  spills  and other  environmental damage
caused by  an oil  company, volatility  of  oil prices  and the  development  of
alternate  sources  of fuel.  Each  of the  above may  affect  the value  of the
Securities  in  the  portfolio.  The  Sponsor  cannot  predict  the  impact  the
above-stated risks may have on the Securities in the portfolio over the one year
life of the Trust.
 
    In connection with the deposit by the Sponsor of cash (or a letter of credit
in lieu of cash) with instructions to purchase additional Securities in order to
create  Additional Units, to the extent that  the price of a Security fluctuates
between the time the cash is deposited and the time the cash is used to purchase
the Security, Units (including  previously issued Units)  may represent more  or
less  of that Security and more or less  of other Securities in the Portfolio of
the Trust. In  addition, the  brokerage fees incurred  in purchasing  Securities
with  such  deposited cash  will  be borne  by the  Trust.  Any Unit  Holder who
purchased Units prior  to the purchase  of Securities with  such deposited  cash
would experience dilution as a result of any such brokerage fees.
 
    SPECIAL CHARACTERISTICS OF THE TRUST
 
   
    --SECURITIES  SELECTION.  The Trust  Portfolio  consists of  the  ten common
stocks in the Dow Jones Industrial Average ("DJIA") having the highest  dividend
yield  as of March  29, 1996. Dow Jones  and Company Inc.  ("Dow Jones") has not
participated in any way in the creation of the Trust or in the selection of  the
stocks  included in the Trust and has not approved any of the information herein
relating thereto. The  yield for each  stock was calculated  by annualizing  the
last  quarterly ordinary dividend declared  and dividing the annualized dividend
by the market  value of  the stock.  Such formula  (an objective  determination)
served  as the basis  for the Sponsor's selection  of the ten  stocks in the Dow
Jones Industrial Average having  the highest dividend  yield. The philosophy  is
simple.  The Trust does not require  sophisticated analysis or an explanation of
complex investment strategies,  just the  pure and  simple concept  of buying  a
quality  portfolio of stocks with  the highest dividend yields  of the stocks in
the DJIA in one convenient  purchase. The Securities were selected  irrespective
of  any buy or sell recommendation by the Sponsor. Investing in DJIA stocks with
the highest dividend  yields may be  effective as well  as conservative  because
regular  dividends  are  common  for established  companies  and  dividends have
accounted for a  substantial portion of  the total  return on DJIA  stocks as  a
group.
    
 
   
    Investors should note that the above criteria were applied to the Securities
selected  for inclusion in the Trust Portfolio  as of March 29, 1996. Subsequent
to March 29, 1996, the Securities may no longer rank among the ten stocks in the
DJIA having the  highest dividend  yield, the yields  on the  Securities in  the
portfolio  may change or the  Securities may no longer  be included in the DJIA.
However, the Sponsor  may, on  and subsequent to  the Date  of Deposit,  deposit
additional  Securities which  reflect the Portfolio  as of the  Date of Deposit,
subject to permitted adjustments,  and sell such  additional Units created.  The
sale  of additional  Units and  the sale  of Units  in the  secondary market may
continue even though the Securities would  no longer be chosen for deposit  into
the Trust if the selection process were to be made at such later time.
    
 
    Simple  strategies can  sometimes be the  most effective.  To outperform the
market is more difficult than just outperforming other asset classes. The  Trust
seeks  a higher total return than the DJIA by acquiring the ten common stocks in
the DJIA having the highest dividend yields on the Date of Deposit, and  holding
them  for  about  one  year.  Purchasing a  portfolio  of  these  stocks through
 
                                      vii
<PAGE>
an investment  in the  Trust as  opposed to  one or  two individual  stocks  may
achieve  better overall performance  and will achieve  diversification. There is
only one  investment decision  instead of  ten, and  four distributions  to  the
investor  during the one-year life of the  Trust instead of 40. An investment in
the Trust can  be cost-efficient,  avoiding the  odd-lot costs  of buying  small
quantities of securities directly. Investment in a number of companies with high
dividends  relative to  their stock prices  is designed to  increase the Trust's
potential for higher returns. The Trust's return may consist of a combination of
capital appreciation and current dividend income.
 
THE DOW, HISTORICALLY SPEAKING
 
    The first DJIA, consisting  of 12 stocks, was  published in THE WALL  STREET
JOURNAL  in 1896. The list grew to 20 stocks in 1916 and to 30 stocks on October
1, 1928.  Taking into  account a  number of  names changes,  9 of  the  original
companies  are still in the DJIA today.  For two periods of 17 consecutive years
each, there were no changes  to the list: March 14,  1939-July 1956 and June  1,
1959-August 6, 1976.

    The  Dow Jones Industrial Average is comprised of 30 common stocks chosen by
the editors of The Wall Street Journal as representative of the broad market and
of American industry. The  companies are major factors  in their industries  and
their stocks are widely held by individuals and institutional investors.
 
    Changes  in the  components are  made entirely  by the  editors of  The Wall
Street Journal without consultation  with the companies,  the stock exchange  or
any  official agency. For the sake of  continuity, such changes are made rarely.
Most substitutions  have been  the result  of  mergers, but  from time  to  time
changes  may be  made to  achieve a  better representation.  Notwithstanding the
foregoing, Dow Jones expressly  reserves the right to  change the components  of
the Dow Jones Industrial Average at any time for any reason.

</TABLE>
    
 
   
    The  Select 10  Industrial Portfolio seeks  to achieve  a better performance
than the Dow Jones  Industrial Average (DJIA) through  investment for about  one
year  in the ten common stocks in the  DJIA having the highest dividend yield as
of March  29, 1996.  In most  instances in  the last  20 years,  a  hypothetical
strategy  of investing in  approximately equal values of  these stocks each year
would have yielded a higher  total return than an  investment in all the  stocks
which make up the DJIA.
    
 
    The  average  annual return  reflects a  rate of  growth per  year (assuming
reinvestment of all dividends at the end  of each period) that the DJIA and  the
Select  10  strategy would  have provided  over  the above  20 year  period. The
returns shown above are not guarantees  of future performance and should not  be
used  as a predictor of returns to be expected in connection with the Portfolio.
Such returns do not  reflect sales charges, commissions,  expenses or taxes.  As
indicated in the above tables, the Select 10 strategy underperformed the DJIA in
certain years and there can be no assurance that the portfolio of the Trust will
outperform the DJIA over the life of the Trust.

    PERFORMANCE INFORMATION--Information on the performance of the Trust, one or
more  Select 10 series and the Select 10  stock strategy on the basis of changes
in  Unit  price  (total   return)  may  be  included   from  time  to  time   in
advertisements,  sales  literature and  reports to  current or  prospective Unit
Holders. Average annualized returns may also be shown for consecutive series  of
the same Select 10 Industrial Portfolio cycle. Information on the performance of
the  Select 10 stocks contained in this Prospectus, as further updated, may also
be included from time to time in such material. Performance of individual Select
10 Portfolios may also be  shown along with performance  of the other Select  10
Portfolios  for comparable (though  not necessarily identical)  periods and on a
combined basis. Total return  is computed by dividing  share price changes  plus
dividends  reinvested at the end of each  year by initial share prices, but does
not reflect commissions,  taxes or  Portfolio sales charges  or expenses,  which
would  decrease the  return. Average  annualized return  figures of  a Portfolio
would reflect deduction of the maximum sales charge. Material reflecting  annual
performance  of a hypothetical  investment in the Select  10 stock strategy does
not reflect commissions, taxes, sales charges or expenses. No provision is  made
for any income taxes payable. Past performance cannot guarantee future results.

are the  responsibility  of the  Trustee.  (See note  (f)  to the  Statement  of
Financial  Condition).  Our responsibility  is to  express  an opinion  on these
financial statements based on our audit.
    
 
   
    We conducted  our  audit  in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation  of an irrevocable letter of  credit and contracts for the purchase
of securities, as shown in the statement of financial condition and schedule  of
portfolio  securities as of March  29, 1996, by correspondence  with The Bank of
New  York,  the  Trustee.  An  audit  also  includes  assessing  the  accounting
principles  used  and significant  estimates  made by  the  Trustee, as  well as
evaluating the overall  financial statement  presentation. We  believe that  our
audit provides a reasonable basis for our opinion.
    
 
   
    In  our  opinion,  the  statement of  financial  condition  and  schedule of
portfolio securities referred to above present fairly, in all material respects,
the financial  position  of  the  Dean Witter  Select  Equity  Trust  Select  10
Industrial  Portfolio 96-2  as of  March 29,  1996 in  conformity with generally
accepted accounting principles.

- ------------------------
(a)  The aggregate value of the Securities represented by Contracts to  Purchase
     listed under "Schedule of Portfolio Securities" and their cost to the Trust
     are the same. The value is determined by the Trustee on the basis set forth
     under  "Public Offering of Units--Public Offering  Price" as of the Date of
     Deposit. An irrevocable letter of credit drawn on Banque Paribas, New  York
     Branch, in the amount of $300,000.00 has been deposited with the Trustee.
 
(b)  Organizational  costs borne  by the  Trust have  been deferred  and will be
     amortized over  the  life of  the  Trust. Organizational  costs  have  been
     estimated  based on a Trust with  projected total assets of $150.0 million.
     To the extent the assets  of the Trust are  fewer or greater, the  estimate
     may vary.
 
(c)  Represents the aggregate amount of mandatory distributions of $2.00 per 100
     Units  per month payable on  the last business day  of each month from June
     28, 1996 through March 31, 1997.  Distributions will be made to an  account
     maintained  by  the Trustee  from which  the  Unit Holders'  Deferred Sales
     Charge obligation to the Sponsor will  be satisfied. If Units are  redeemed
     prior  to  March  31,  1997,  the  remaining  portion  of  the distribution
     applicable to  such  Units will  be  transferred  to such  account  on  the
     redemption date.
 
(d)  The  aggregate Public  Offering Price  is computed  on the  basis set forth
     under  "Public  Offering  of  Units--Public  Offering  Price"  as  of   the
     evaluation time on the Date of Deposit.
 
(e)  The  aggregate sales charge of  2.90% of the Public  Offering Price per 100
     Units is  computed  on  the  basis set  forth  under  "Public  Offering  of
     Units--Public Offering Price".
 
(f)  The  Trustee  has  custody of  and  responsibility for  all  accounting and
     financial books,  records, financial  statements and  related data  of  the
     Trust  and  is responsible  for establishing  and  maintaining a  system of
     internal controls directly related to,  and designed to provide  reasonable
     assurance  as to the  integrity and reliability  of, financial reporting of
     the Trust. The Trustee is also  responsible for all estimates and  accruals
     reflected  in the Trust's financial  statements. The Trustee determines the
     price for  each underlying  Security included  in the  Trust's Schedule  of
     Portfolio  Securities  on  the  basis  set  forth  in  "Public  Offering of
     Units--Public Offering Price". Under the Securities Act of 1933, as amended
     (the "Act"), the Sponsor is deemed to be an issuer of the Trust's Units. As
     such, the Sponsor has  the responsibility of an  issuer under the Act  with
     respect  to financial statements of the  Trust included in the Registration
     Statement under the Act and amendments thereto.

Dean Witter Select Equity Trust
Select 10 Industrial Portfolio 96-2
    
- ----------------------------------------------
    AN OPPORTUNITY TO INVEST FOR INCOME AND
    ABOVE-AVERAGE GROWTH POTENTIAL
- -------------------------------------------------------------
 
   
    - PORTFOLIO SELECTION -- Investment in the 10 common stocks in the Dow Jones
      Industrial  Average having  the highest  dividend yield  (as of  March 29,
      1996) offers  an  opportunity to  earn  income with  above-average  growth
      potential in the next year.*
    
 
    - DIVERSIFICATION -- Risk is reduced because your investment is spread among
      10  common stocks from various industry groups. Individual investors would
      require  a  substantial  capital  commitment  to  achieve  the  level   of
      diversification offered by the Trust without incurring odd-lot charges.
 
    - REINVESTMENT   OPTION  --  Investors  may   elect  to  have  distributions
      automatically reinvested in additional units  of the Trust subject to  the
      then remaining deferred sales charge.
 
    - LOW  MINIMUM INVESTMENT  -- The Trust  is priced at  approximately $10 per
      unit and the minimum investment is $1,000 although investors may  purchase
      any number of additional units they wish.
 
    - EASY LIQUIDITY -- The Sponsor intends to maintain a secondary market where
      you  can sell  units at  the then-current  market value  without a  fee or
      penalty other than the payment of any deferred sales charge then due.
   
 
    
 
   
    - DEAN WITTER DIRECT  INVEST-SM- --  Investing in the  Select 10  Industrial
      Portfolio  is made even easier through  DIRECT INVEST, since purchases and

INVEST IN THE 10 HIGHEST YIELDING STOCKS
IN THE DOW JONES INDUSTRIAL AVERAGE FOR
AS LITTLE AS $1,000.
- ---------------------------------------------------------
THE SELECT EQUITY TRUSTS
 
       Achieving  financial  success  in  today's  dynamic  markets  depends  on
       selecting  the right  investment strategy.  As new  opportunities emerge,
       sparked by changing business trends, market strategies must be geared  to
       capitalize  on  them.  Because  such  opportunities  may  not  be  easily
       identified by individual investors, Dean Witter has developed the  Select
       Equity  Trusts  that  offer  investors a  simple  and  convenient  way to
       participate in the equity market.
- --------------------------------------------------------------------------------
PORTFOLIO SELECTION
 
   
       The Select 10 Industrial  Portfolio consists of the  10 common stocks  in
       the  Dow Jones Industrial Average having the highest dividend yield as of
       March 29, 1996. The Trust is specifically designed for investors  seeking
       income  and above-average growth potential. Because  the Trust is a fixed
       portfolio of preselected securities, purchasers know in advance what they
       are investing in.
    
- --------------------------------------------------------------------------------
RISK FACTORS--SPECIAL CONSIDERATIONS
 
       The risks of an investment in Units of the Trust include price volatility
       resulting from factors  affecting the  common stock  of the  issuer of  a
       portfolio  security in particular and the  equity markets in general. The
       risks associated with an  investment in common stock  of oil and  related
       products  issuers  is  also present  as  the  portfolio of  the  Trust is
       concentrated in the stock of such issuers.
- --------------------------------------------------------------------------------
DIVERSIFICATION
 
       Risk is reduced through the Trust because it allows you to participate in
       a diversified  portfolio  of stocks.  Although  there are  certain  risks
       associated with investment in common stocks, your risk is reduced because
       your  capital is divided among 10 stocks from various industry groups. It
       would be difficult for the average investor to achieve a comparable level
       of diversification, without  making a substantial  capital commitment  or
       incurring odd-lot charges.
- --------------------------------------------------------------------------------
REINVESTMENT OPTION
 
       Investors  may elect  to have  distributions automatically  reinvested in
       additional units  of the  Trust subject  to the  then remaining  deferred
       sales charge.
- --------------------------------------------------------------------------------
COST EFFECTIVE
 
       CONVENIENT PURCHASE PRICE/NO ODD-LOT PENALTIES
       Typically stocks purchased in amounts less than 100 shares are subject to
       odd-lot  penalties. If  you were  to purchase 100  shares of  each of the
       stocks in this portfolio, it would require a large commitment of capital.
       If you were to  purchase smaller amounts of  each stock, you would  incur
       odd-lot  penalties  on many  of your  purchases. Our  convenient purchase
       price of approximately $10  per unit with a  minimum purchase of  $1,000,
       allows  you to invest in  all the stocks in  an affordable manner. Volume
       discounts are available beginning on orders of $25,000.
 
    The Offering Features are a part of the prospectus and should be read in
                                  conjunction
                          with the entire prospectus.
<PAGE>
- ---------------------------------------------------
FLEXIBILITY THROUGH EXCHANGE PRIVILEGES
 
       Investors may elect, at any time, to exchange or rollover these units for
       units of another Dean Witter Select Trust at a sales charge less than the
       sales charge that a new investor would pay.
- --------------------------------------------------------------------------------
SHORT-TERM LIFE
 
       The Trust will terminate  in approximately one  year. After this  period,
       the  Portfolio will liquidate.  Unit Holders owning  at least 2,500 units
       may elect to  receive distributions in  respect of their  Units in  kind.
       Unit  Holders not so electing will receive cash. You may, of course, sell
       or redeem your Units prior to the Trust's termination.
- --------------------------------------------------------------------------------
EASY LIQUIDITY
 
       Although not  obligated to  do  so, Dean  Witter  intends to  maintain  a
       secondary  market for the resale of Units. All or a portion of your Units
       may be liquidated  at any time,  without charge other  than any  deferred
       sales  charge then  payable. The  price you  receive will  reflect market
       conditions and could be more or less than the price originally paid.
- --------------------------------------------------------------------------------
RETIREMENT ACCOUNTS
 
       This Trust may be  an attractive investment  vehicle for a  self-directed
       IRA  or self-directed self-employed retirement plan ("Keogh plan"). As an
       income- and growth-oriented investment, it  may be a suitable  complement
       to achieve overall portfolio diversification.
- --------------------------------------------------------------------------------
EASE OF OWNERSHIP
 
       The  usual chores associated with individual ownership of stocks--keeping
       records, safekeeping of certificates, and more--are eliminated through  a
       single  investment in  the Trust.  You will  receive year-end information
       from the Trustee, including Federal income tax information.

DEAN WITTER DIRECT INVEST-SM-
    
 
   
       DIRECT  INVEST  is  an  automatic   investment  program  that  can   help
       individuals  invest  for their  future, now.  Dean Witter  created DIRECT
       INVEST because  preparing for  the future,  such as  financing a  college
       education,  a  down  payment  on  a  new  house,  or  retirement,  can be
       difficult. Through  DIRECT INVEST,  regular deductions  from a  checking,
       savings  account  or  Dean  Witter  Active  Assets-Registered  Trademark-
       Accounts are  used  to  purchase  units of  the  DEAN  WITTER  SELECT  10
       INDUSTRIAL  PORTFOLIO  without writing  any checks!  The program  has the
       additional benefits of allowing investors to choose their own  investment

                               PROSPECTUS PART B
                        DEAN WITTER SELECT EQUITY TRUST
 
                                  INTRODUCTION
 
   
    This series of the Dean Witter Select Equity Trust (the "Trust") was created
under  the laws  of the  State of  New York  pursuant to  a Trust  Indenture and
Agreement (the  "Indenture")  and  a  related  Reference  Trust  Agreement  (the
"Agreement") (collectively, the "Indenture and Agreement")*, between Dean Witter
Reynolds  Inc. (the  "Sponsor") and  The Bank of  New York  (the "Trustee"). The
Sponsor is  a principal  operating subsidiary  of Dean  Witter, Discover  &  Co.
("DWDC"),  a publicly-held corporation. (See:  "Sponsor".) The objectives of the
Trust are income  and above  average growth  potential through  investment in  a
fixed portfolio of Securities (the "Portfolio") of publicly-traded common stock.
There  is no assurance that these objectives  will be met because the Securities
may appreciate or depreciate in value  (or pay dividends) depending on the  full
range  of economic and market  influences affecting corporate profitability, the
financial condition of issuers  and the prices of  equity securities in  general
and the Securities in particular.
    
 
    On  the date of creation  of the Trust (the  "Date of Deposit"), the Sponsor
deposited  with  the  Trustee  certain   securities  and  contracts  and   funds
(represented  by  irrevocable letter(s)  of  credit issued  by  major commercial
bank(s)) for the purchase of such securities (collectively, the "Securities") at
prices equal to the market value of such Securities as determined by the Trustee
as of the Date of Deposit  and/or cash (or a letter  of credit in lieu of  cash)
with instructions to the Trustee to purchase such Securities. (See: "Schedule of
Portfolio Securities".) The Trust was created simultaneously with the deposit of
the  Securities with  the Trustee  and the  execution of  the Indenture  and the
Agreement. The Trustee then immediately delivered to the Sponsor certificates of
beneficial interest (the  "Certificates") representing the  units (the  "Units")
comprising  the  entire ownership  of the  Trust.  Through this  prospectus (the
"Prospectus"), the Sponsor is offering the Units, including Additional Units, as
defined below, for sale  to the public. The  holders of Certificates (the  "Unit
Holders")  will have the right to have their  Units redeemed at a price based on
the market value of  the Securities (the "Redemption  Value") if they cannot  be
sold  in  the secondary  market which  the Sponsor,  although not  obligated to,
proposes to maintain. In addition, the Sponsor may offer for sale, through  this
Prospectus, Units which the Sponsor may have repurchased in the secondary market
or  upon  the  tender  of  such  Units  for  redemption.  The  Trustee  has  not
participated in  the selection  of Securities  for the  Trust, and  neither  the
Sponsor  nor the Trustee will  be liable in any way  for any default, failure or
defect in any Securities.
 
   
    With the deposit of the Securities in the Trust on the Date of Deposit,  the
Sponsor established a proportionate relationship between the number of shares of
each Security in the Portfolio. (The original proportionate relationships on the
Date  of  Deposit are  set  forth in  "Schedule  of Portfolio  Securities".) The
original proportionate  relationships are  subject to  adjustment under  certain
limited   circumstances.   (See:   "Administration   of   the   Trust--Portfolio
Supervision".) The Sponsor  is permitted  under the Indenture  and Agreement  to
deposit  additional  Securities,  contracts  to  purchase  additional Securities
together with a letter of credit and/or cash  (or a letter of credit in lieu  of
cash)  with instructions  to the  Trustee to  purchase additional  Securities in
order to  create  additional Units  ("Additional  Units"). Any  such  additional
deposits  made in  the 90 day  period following  the creation of  the Trust will
consist of securities identical  to those already  in the Trust  and will be  in
amounts  which maintain, to  the extent practicable,  the original proportionate
relationship between the number of shares of  each Security and any cash in  the
Portfolio.  It may not be possible  to maintain the exact original proportionate
relationship because of price changes or other reasons. Any cash deposited  with
instructions  to purchase Securities may be  held in an interest bearing account
by the Trustee. Any  interest earned on  such cash will be  the property of  the
Trust.  Any cash deposited  with instruction to purchase  Securities not used to
purchase Securities and any

* Reference is hereby made  to said Indenture and  Agreement and any  statements
  contained  herein are  qualified in their  entirety by the  provisions of said
  Indenture and Agreement.
<PAGE>
interest not used to pay Trust expenses  will be distributed to Unit Holders  on
the earlier of the first Distribution Date or 90 days after the Date of Deposit.
Additional  Units may be continuously offered for sale to the public by means of
this Prospectus. Subsequent to the 90  day period following the Date of  Deposit
any  deposit  of  additional  Securities and  cash  must  exactly  replicate the
portfolio immediately  prior to  such  deposit. The  Sponsor may  acquire  large
volumes  of additional Securities for deposit into the Trust over a short period
of time.  Such  acquisitions  may tend  to  raise  the market  prices  of  these
Securities. The Sponsor cannot currently predict the actual market impact of the
Sponsor's  purchases  of additional  Securities,  because the  actual  volume of
Securities to be purchased and  the supply and price  of such Securities is  not
known.
 
    Units  will be sold to investors at  the Public Offering Price next computed
after receipt of the investor's order to purchase Units, if Units are  available
to  fill orders on the day that that price is set. If Units are not available or
are insufficient to fill the order, the investor's order will be rejected by the
Sponsor. The  number of  Units  available may  be  insufficient to  meet  demand
because  of the Sponsor's inability  to or decision not  to purchase and deposit
underlying Securities  in  amounts  sufficient  to  maintain  the  proportionate
numbers  of shares of each Security as  required to create additional Units. The
Sponsor may, if unable to accept orders  on any given day, offer to execute  the
order as soon as sufficient Units can be created. An investor who agrees to this
will be deemed to place a new order for that number of Units each day until that
order  is accepted. The investor's  order will then be  executed, when Units are
available, at the Public  Offering Price next  calculated after such  continuing
order  is accepted. The investor will, of course, be able to revoke his purchase
offer at any time prior to acceptance  by the Sponsor. The Sponsor will  execute
orders  to purchase  in the  order it determines  that they  are received, i.e.,
orders received first will be filled first, except that indications of  interest
prior  to the effectiveness of  the registration of the  offering of Trust Units
which become orders upon effectiveness will  be accepted according to the  order
in which the indications of interest were received.
 
    On  the  Date of  Deposit, each  Unit  represented the  fractional undivided
interest in the Securities and net income of the Trust set forth under  "Summary
of  Essential Information". Thereafter, if any Units are redeemed, the amount of
Securities in the Trust will be  reduced, and the fractional undivided  interest
represented  by  each  remaining  Unit  in the  balance  of  the  Trust  will be
increased. However, if Additional Units are  issued by the Trust, the  aggregate
value  of the Securities in the Trust  will be increased by amounts allocable to
such Additional Units and the fractional undivided interest in the balance  will
be decreased. In connection with the deposit by the Sponsor of cash (or a letter
of  credit in lieu of cash)  with instructions to purchase additional Securities
in order to create Additional Units, to the extent that the price of a  Security
fluctuates  between the time the cash is deposited and the time the cash is used
to  purchase  the  Security,  Units  (including  previously  issued  Units)  may
represent  more or less of that Security and more or less of other Securities in
the Portfolio of the  Trust. Units will remain  outstanding until redeemed  upon
tender  to the  Trustee by any  Unit Holder  (which may include  the Sponsor) or
until the termination of the Trust pursuant to the Indenture and Agreement.
 
                                   THE TRUST
 
RISK FACTORS--SPECIAL CONSIDERATIONS
 
    An investment in Units of the Trust should be made with an understanding  of
the  risks  which  an investment  in  publicly-traded common  stock  may entail,
including the risk that the value of  the Portfolio and hence of the Units  will
decline  with decreases in the market value of the Securities. The Trust will be
terminated and liquidated no later than the Mandatory Termination Date set forth
in the "Summary of Essential Information".
 
    On each Deferred Sales Charge Payment Date Securities will be sold pro  rata
in  an amount equal to $2.00 per 100  Units to pay the Deferred Sales Charge and
the proceeds will be distributed to the  Sponsor. As Securities are sold to  pay
the  Deferred Sales Charge a Unit Holder's assets will be reduced and income per
Unit may be reduced.

<PAGE>
SUMMARY DESCRIPTION OF THE PORTFOLIO
 
    As used herein,  the term "Common  Stocks" refers to  the common stocks  (or
contracts to purchase such common stocks) (any such contracts to purchase common
stocks  to  be accompanied  by  an irrevocable  letter  of credit  sufficient to
perform such contracts), initially  deposited in the  Trust and described  under
"Schedule   of  Portfolio  Securities".  The   term  "Securities"  includes  any
additional common  stock  or  contracts  to  purchase  additional  common  stock
together  with  the  corresponding irrevocable  letter  of  credit, subsequently
acquired by the Trust pursuant to the Indenture and Agreement.
 
    An investment in  Units of the  Trust should be  made with an  understanding
that  the value of the underlying Securities,  and therefore the value of Units,
will fluctuate, depending upon the full range of economic and market  influences
which may affect the market value of such Securities. Certain risks are inherent
in  an investment  in equity securities,  including the risk  that the financial
condition of one  or more of  the issuers of  the Securities may  worsen or  the
general condition of the common stock market may weaken. In such case, the value
of  the Portfolio Securities  and hence the  value of Units  may decline. Common
stocks are susceptible  to general stock  market movements and  to volatile  and
unpredictable  increases  and decreases  in value  as  market confidence  in and
perceptions of the issuers change from time to time. Such perceptions are  based
upon  varying reactions to  such factors as  expectations regarding domestic and
foreign economic, monetary  and fiscal policies,  inflation and interest  rates,
currency  exchange  rates,  economic  expansion or  contraction,  and  global or
regional political, economic  or banking crises.  In addition, investors  should
understand  that  there  are certain  payment  risks involved  in  owning common
stocks, including  risks  arising from  the  fact  that holders  of  common  and
preferred  stocks  have rights  to receive  payments from  the issuers  of those
stocks that are generally inferior to those of creditors of, or holders of  debt
obligations  issued  by, such  issuers. Furthermore,  the  rights of  holders of
common stocks are inferior to the rights of holders of preferred stocks. Holders
of common stocks  of the  type held  in the Portfolio  have a  right to  receive
dividends  only when, as  and if, and  in the amounts,  declared by the issuer's
board of directors and to participate  in amounts available for distribution  by
the  issuer only after all other claims on the issuer have been paid or provided
for. By  contrast,  holders  of  preferred stocks  have  the  right  to  receive
dividends  at  a  fixed rate  when  and as  declared  by the  issuer's  board of
directors, normally on a cumulative basis, but do not ordinarily participate  in
other  amounts available for distribution by the issuing corporation. Cumulative
preferred stock dividends must  be paid before common  stock dividends, and  any
cumulative preferred stock dividend omitted is added to future dividends payable
to  the holders  of such cumulative  preferred stock. Preferred  stocks are also
entitled to rights on  liquidation which are senior  to those of common  stocks.
For  these  reasons,  preferred  stocks entail  less  risk  than  common stocks.
However,  neither  preferred  nor  common  stocks  represent  an  obligation  or
liability  of the issuer and  therefore do not offer  any assurance of income or
provide the degree of protection of capital of debt securities. The issuance  of
debt securities (as compared with both preferred and common stock) and preferred
stock  (as compared with common  stock) will create prior  claims for payment of
principal and interest (in  the case of debt  securities) and dividends (in  the
case  of  preferred securities)  which could  adversely  affect the  ability and
inclination of the issuer to declare or pay dividends on its common stock or the
rights of holders  of common stock  with respect  to assets of  the issuer  upon
liquidation  or bankruptcy. Further, unlike debt securities which typically have
a stated principal amount  payable at maturity (which  value will be subject  to
market  fluctuations prior  thereto), or  preferred stocks  which typically have
liquidation  preference  and  which  may  have  stated  optional  or   mandatory
redemption provisions, common stocks have neither a fixed principal amount nor a
maturity  date and have values  which are subject to  market fluctuations for as
long as the common  stocks remain outstanding.  Additionally, market timing  and
volume  trading will also  affect the underlying  value of Securities, including
the Sponsor's  buying  of  additional  Securities and  the  Trust's  selling  of
Securities  during the  Liquidation Period. The  value of the  Securities in the
Portfolio thus may be expected to fluctuate over the entire life of the Trust to
values higher or lower than those prevailing on the Date of Deposit. The Sponsor
may direct  the  Trustee  to  dispose  of  Securities  under  certain  specified
circumstances   (see  "Administration  of  the  Trust--Portfolio  Supervision").
However, Securities  will  not be  disposed  of solely  as  a result  of  normal
fluctuations in market value.
 
                                       3

    There  can  be no  assurance  that a  market  will be  made  for any  of the
Securities, that any  market for  the Securities will  be maintained  or of  the
liquidity  of the Securities in any markets  made. In addition, the Trust may be
restricted under the Investment Company Act  of 1940 from selling Securities  to
the  Sponsor. The price at which the  Securities may be sold to meet redemptions
and the value of the Trust will be adversely affected if trading markets for the
Securities are limited or absent.
 
OBJECTIVES AND SECURITIES SELECTION
 
    The objectives of  the Trust are  (i) to  provide income and  (ii) to  offer
above-average  growth potential through an investment for approximately one year
in a fixed diversified portfolio of Securities chosen in the manner described in
the "Summary of Essential Information" in Part A herein. There is, of course, no
guarantee that the Trust's objectives will be achieved.
 
    The Trust  consists of  such of  the Securities  listed under  "Schedule  of
Portfolio  Securities" as may continue to be held from time to time in the Trust
and any additional Securities and/or contributed  cash acquired and held by  the
Trust  pursuant to the  provisions of the  Indenture together with undistributed
income therefrom  and  undistributed  cash  realized  from  the  disposition  of
Securities  (See: "Administration  of the Trust").  Neither the  Sponsor nor the
Trustee shall be liable in any way for any default, failure or defect in any  of
the  Securities. However,  should any contract  deposited hereunder  fail and no
substitute Security be  acquired, the  Sponsor shall  cause to  be refunded  the
sales charge relating to such security, plus the pro rata portion of the cost of
the failed contract listed under "Schedule of Portfolio Securities".
 
    Because certain Securities from time to time may be sold or their percentage
reduced  under certain  circumstances described  herein, and  because additional
Securities may be deposited into the Trust  from time to time, the Trust is  not
expected  to retain  for any  length of time  its present  size and composition.
(See: "Administration of the Trust--Portfolio Supervision".)
 
    The Trust is organized as  a unit investment trust  and not as a  management
investment  company.  Therefore, neither  the Trustee  nor  the Sponsor  has the
authority to  manage the  Trust's assets  in  an attempt  to take  advantage  of
various  market conditions to improve the  Trust's net asset value, and further,
the Trust's  Securities may  be disposed  of only  under limited  circumstances.
(See: "Administration of the Trust--Portfolio Supervision".)
 
    There  is no assurance  that any dividends  will be declared  or paid in the
future on the Securities initially deposited or to be deposited subsequently  in
the Trust.
 
DISTRIBUTION
 
    The  Record Dates and the Distribution Dates are set forth in Part A hereto.
(See: "Summary of Essential Information".)  The distributions will be an  amount
equal  to such Unit Holder's  pro rata portion of  the amount of dividend income
received by  the  Trust  and  proceeds of  the  sale  of  Portfolio  Securities,
including  capital gains, not used for the redemption of Units, if any (less the
Trustee's  fees,   Sponsor's   portfolio   supervision   fees   and   expenses).
Distributions  for  the  account of  beneficial  owners of  Units  registered in
"street name" and held by the Sponsor will be made to the investment account  of
such  beneficial  owners  maintained  with the  Sponsor.  Whenever  required for
regulatory or tax purposes or if otherwise directed by the Sponsor, the  Trustee
may  make special distributions on special distribution dates to Unit Holders of
record on special record dates declared by the Trustee.
 
                            TAX STATUS OF THE TRUST
 
    In the opinion of Cahill Gordon & Reindel, special counsel for the  Sponsor,
under existing Federal income tax law:
 
        The  Trust is  not an association  taxable as a  corporation for Federal
    income tax purposes,  and income received  by the Trust  will be treated  as
    income of the Unit Holders in the manner set forth below.
 
                                       4
<PAGE>
        Each  Unit Holder will be considered the  owner of a pro rata portion of
    each asset in the Trust under the grantor trust rules of Sections 671-678 of
    the Internal Revenue Code  of 1986, as amended  (the "Code"). The total  tax
    cost of each Unit will equal the cost of Units (including the up front sales
    charge) plus the amount of organizational expenses borne by the Unit Holder.
    A  Unit Holder should determine  the tax cost for  each asset represented by
    the Holder's Units by  allocating the total cost  for such Units  (including
    the  Initial Sales Charge) among the assets  in the Trust represented by the
    Units in proportion to the relative  fair market values thereof on the  date
    the Unit Holder purchases such Units. The proceeds received by a Unit Holder
    upon termination of the Trust or redemption of Units will reflect the actual
    amounts  paid to them,  net of the  Deferred Sales Charge.  The relevant tax
    reporting forms sent to Unit Holders will reflect the actual amounts paid to
    them, net of the Deferred Sales Charge. Accordingly, Unit Holders should not
    increase the total cost for their Units by the amount of the Deferred  Sales
    Charge.
 
        A  Unit Holder will be considered to  have received all of the dividends
    paid on the Holder's pro rata  portion of each Security when such  dividends
    are received by the Trust including the portion of such dividend used to pay
    ongoing  expenses and  organizational expenses. In  the case  of a corporate
    Unit Holder,  such dividends  will qualify  for the  70% dividends  received
    deduction  for corporations to the same extent as though the dividend paying
    stock were held directly  by the corporate Unit  Holder. An individual  Unit
    Holder who itemizes deductions will be entitled to an itemized deduction for
    the Holder's pro rata share of fees and expenses paid by the Trust as though
    such  fees and expenses were  paid directly by the  Unit Holder, but only to
    the  extent  that  this  amount  together  with  the  Unit  Holder's   other
    miscellaneous deductions exceeds 2% of the Holder's adjusted gross income. A
    corporate Unit Holder will not be subject to this 2% floor.
 
        Under  the position  taken by  the Internal  Revenue Service  in Revenue
    Ruling 90-7, a  distribution by  the Trustee  to a  Unit Holder  (or to  the
    Holder's  agent) of such Holder's  PRO RATA share of  the Securities in kind
    upon redemption or termination of the Trust  will not be a taxable event  to
    the Unit Holder. Such Unit Holder's basis for Securities so distributed will
    be  equal  to  the  Holder's  basis  for  the  same  Securities  (previously
    represented by  the  Holder's Units)  prior  to such  distribution  and  the
    holding  period for such Securities will be the shorter of the period during
    which the Unit Holder held the Units and the period for which the Securities
    were held in  the Trust. A  Unit Holder will  have a taxable  gain or  loss,
    which  will be a capital gain  or loss except in the  case of a dealer, when
    the Unit Holder disposes of such Securities in a taxable transfer.
 
        Under the income tax laws of the  State and City of New York, the  Trust
    is  not an association taxable as a  corporation and the income of the Trust
    will be treated as the income of the Unit Holders.
 
    If the proceeds  received by the  Trust upon  the sale or  redemption of  an
underlying  Security exceed a  Unit Holder's adjusted tax  cost allocable to the
Security disposed of, that Unit Holder will realize a taxable gain to the extent
of such excess. Conversely, if the proceeds received by the Trust upon the  sale
or  redemption of an underlying Security are  less than a Unit Holder's adjusted
tax cost allocable to the Security disposed of, that Unit Holder will realize  a
loss  for  tax  purposes to  the  extent  of such  difference  except  that upon
reinvestment of proceeds in a New  Series the Internal Revenue Service may  seek
to disallow such loss to the extent that the underlying securities in each trust
are  substantially identical and the  purchase of units of  the New Series takes
place less than thirty-one days after the sale of the underlying Security. Under
the Code, net capital gain (i.e., the excess of net long-term capital gain  over
net  short-term capital loss) of individuals, estates and trusts is subject to a
maximum nominal tax rate of 28%. Such net capital gain may, however, result in a
disallowance  of  itemized  deductions   and/or  affect  a  personal   exemption
phase-out.  The maximum lower net capital gain rate will be unavailable to those
Unit Holders who have held their units for less than a year and a day as of  the
Mandatory  Termination Date (or earlier termination of  the Trust) or any day on
which a Unit Holder's units are exchanged or rolled over.
 
    Each Unit Holder should consult his, her or its tax advisor with respect  to
the application of the above general information to his, her or its own personal
situation.

                                RETIREMENT PLANS
 
    Units  of  the Trust  may be  suited for  purchase by  Individual Retirement
Accounts and  pension plans  or profit  sharing and  other qualified  retirement
plans.  Investors  considering  participation  in any  such  plan  should review
specific tax laws and  pending legislation relating  thereto and should  consult
their   attorneys  or  tax  advisors  with  respect  to  the  establishment  and
maintenance of any such plan.
 
    A qualified retirement  plan provides  employee retirement  benefits and  is
funded  by  contributions  from  the  employer  (including  contributions  by  a
self-employed individual, in  which case the  plan is sometimes  called a  Keogh
plan).  The  contributions are,  within  limits, deductible  in  determining the
taxable income of  the contributing  employer for Federal  income tax  purposes.
Income  received by  the plan  is not taxed  when received  by it  (nor are plan
losses deductible), but distributions  from the plan  are generally included  in
ordinary income of the distributee upon receipt. A lump sum payout of the entire
amount held in such a plan can, however, be eligible for 5 or 10 year averaging.
 
    An  individual  retirement  account (an  "IRA")  is similar  to  a qualified
retirement plan but contributions to an IRA up to $2,000 per year ($2,250 if  at
least  $250 is contributed  for the benefit of  the worker's non-earning spouse)
are generally  made by  an individual  from  earned income,  rather than  by  an
employer.  An individual is permitted to contribute  to an IRA even though he or
she is  also  covered by  a  qualified retirement  plan;  but, in  the  case  of
higher-income  individuals who are active participants in a qualified retirement
plan, IRA contributions are neither currently deductible nor taxed when paid out
by the IRA (although income earned in  the IRA is taxed as ordinary income  when
distributed). The IRA beneficiary must not have attained age 70 1/2 by the close
of  the taxable year  for which an IRA  contribution is made; and  5 and 10 year
averaging is not allowable for IRA distributions.
 
    Distributions from qualified retirement plans must begin in minimum  amounts
no  later than  the April 1  following the  calendar year in  which the employee
attains age 70  1/2 or  within 5 years  after his  or her prior  death if  death
occurs  before  distributions  begin  (with  later  distribution  allowed  for a
surviving spouse  and  with lifetime  annuity-type  payouts to  any  beneficiary
permitted).  Minimum required  distributions from  IRAs are  governed by similar
rules.
 
    Forms and arrangements for establishing qualified retirement plans and  IRAs
are  available from the  Sponsor, as well  as from other  brokerage firms, other
financial institutions and others. Fees and  charges with respect to such  plans
and  IRAs  are not  uniform and  may  vary from  time to  time  as well  as from
institution to institution.
 
    Distributions received from a  qualified retirement plan  or IRA before  the
employee  attains age  59 1/2 are  subject to  a 10% additional  tax, unless the
distribution is (i) made on or after the employee's death, (ii) attributable  to
his  disablement,  (iii) in  the  nature of  a life  annuity,  (iv) made  to the
employee after separation from service after  attainment of age 55, or (v)  made
for  other  reasons  specified  in  the  law.  Qualifying  distributions  from a
qualified retirement  plan  or from  an  IRA may,  however,  be rolled  over  or
transferred  to  another  qualified  retirement  plan  or  IRA  under  specified
circumstances.
 
    The foregoing information  is of a  general nature, does  not purport to  be
complete  and  relates  only  to  the Federal  income  tax  rules  applicable to
qualified retirement plans and IRAs. State  and local tax rules and foreign  tax
regimes  may  treat  qualified  retirement plans  and  IRAs  differently. Anyone
contemplating establishing a qualified retirement plan or IRA or investing funds
of such a plan or IRA in Trust units should consult his, her or its tax  advisor
with  respect to the tax consequences of  any such action and the application of
the foregoing general tax information to his, her or its particular situation.

                            PUBLIC OFFERING OF UNITS
 
PUBLIC OFFERING PRICE
 
    The Public Offering Price of the  Units is calculated daily and is  computed
by  adding  to  the  aggregate  market value  of  the  Portfolio  Securities (as
determined by the  Trustee) next  computed after  receipt of  a purchase  order,
divided  by the number of Units outstanding,  the sales charge shown in "Summary
of Essential Information".  Commissions and  any other  transactional costs,  if
any,  incurred  by the  Sponsor  in connection  with  the deposit  of additional
Securities or contracts to  purchase additional Securities  for the creation  of
Additional  Units will be added to the  Public Offering Price. After the initial
Date of Deposit,  a proportionate  share of amounts  in the  Income Account  and
Principal   Account  and  amounts  receivable   in  respect  of  stocks  trading
ex-dividend (other than money  required to be distributed  to Unit Holders on  a
Distribution  Date and money required to redeem  tendered Units) is added to the
Public Offering Price. In the event a  stock is trading ex-dividend at the  time
of  deposit of additional Securities, an amount equal to the dividend that would
be received if such stock were to receive a dividend will be added to the Public
Offering Price. The Public Offering Price per Unit is calculated to five decimal
places and rounded up or down to three decimal places. The Public Offering Price
on any particular date will vary from  the Public Offering Price on the Date  of
Deposit (set forth in the "Summary of Essential Information") in accordance with
fluctuations  in the  aggregate market  value of  the Securities,  the amount of
available cash on hand in the Trust  and the amount of certain accrued fees  and
expenses.
 
    As  more fully described in the Indenture, the aggregate market value of the
Securities is determined on  each business day by  the Trustee based on  closing
prices  on the  day the  valuation is  made or,  if there  are no  such reported
prices,  by   taking  into   account  the   same  factors   referred  to   under
"Redemption--Computation  of Redemption Price". Determinations are effective for
transactions effected subsequent to the last preceding determination.
 
   
    The sales charge consists  of an Initial Sales  Charge and a Deferred  Sales
Charge.  The Initial  Sales Charge is  computed by deducting  the Deferred Sales
Charge ($20.00 per 100 Units) from the aggregate sales charge. The Initial Sales
Charge paid by a Unit Holder may be  more or less than the Initial Sales  Charge
on  the Date of Deposit based on the  fluctuation of the value of the Securities
on the date of purchase. The Deferred Sales Charge will initially be $20.00  per
100 Units but will be reduced each month by one tenth; the Deferred Sales Charge
will  be  paid  through  monthly  payments of  $2.00  per  100  Units  per month
commencing on  the first  Deferred Sales  Charge Payment  Date as  shown on  the
Summary  of Essential  Information through the  sale of Securities  on each such
date or  distribution of  cash available  for such  payment. To  the extent  the
entire  Deferred Sales Charge  has not been  so paid at  the time of repurchase,
redemption or exchange of the Units, any unpaid amount will be deducted from the
proceeds or in calculating an in kind distribution. For purchases of Units  with
a  value of $25,000 or more, the Initial  Sales Charge is reduced on a graduated
basis as shown below  under "Volume Discount". Units  purchased pursuant to  the
Reinvestment  Program are  subject only to  any remaining  Deferred Sales Charge
payments (see "Reinvestment Program").
    
 
PUBLIC DISTRIBUTION
 
    Units issued on the Date of  Deposit and Additional Units issued in  respect
of  additional deposits of Securities  will be distributed to  the public by the
Sponsor and through dealers at the Public Offering Price determined as  provided
above.  Unsold Units or  Units acquired by  the Sponsor in  the secondary market
referred to below may be  offered to the public by  this Prospectus at the  then
current Public Offering Price determined as provided above.
 
    The  Sponsor intends to qualify Units in  states selected by the Sponsor for
sale by  the  Sponsor  and through  dealers  who  are members  of  the  National
Association  of Securities  Dealers, Inc.  Sales to  dealers during  the initial
offering period will be made at prices which reflect a concession of 70% of  the
applicable sales charge, subject to change from time to time. In addition, sales
of  Units may be  made pursuant to distribution  arrangements with certain banks
and/or   other    entities    subject    to    regulation    by    the    Office
 
                                       7
<PAGE>
of  the  Comptroller  of the  Currency  which  are acting  as  agents  for their
customers. These banks and/or entities are  making Units of the Trust  available
to  their customers on  an agency basis. A  portion of the  sales charge paid by
these customers is  retained by  or remitted  to such  banks or  entities in  an
amount  equal to  the fee customarily  received by  an agent for  acting in such
capacity in  connection  with the  purchase  of Units.  The  Glass-Steagall  Act
prohibits  banks from  underwriting certain  securities, including  Units of the
Trust; however, this Act  does permit certain  agency transactions, and  banking
regulators  have  not indicated  that these  particular agency  transactions are
impermissible under this  Act. In Texas,  as well as  certain other states,  any
bank making Units available must be registered as a broker-dealer in that State.
The Sponsor reserves the right to reject, in whole or in part, any order for the
purchase of Units.
 
SECONDARY MARKET
 
    While  not obligated  to do  so, it  is the  Sponsor's present  intention to
maintain, at its expense,  a secondary market  for Units of  this series of  the
Dean  Witter Select Equity  Trust and to continuously  offer to repurchase Units
from Unit Holders at  the Sponsor's Repurchase  Price. The Sponsor's  Repurchase
Price  is computed  by adding to  the aggregate  value of the  Securities in the
Trust, any cash on  hand in the Trust  including dividends receivable on  stocks
trading ex-dividend (other than money required to redeem tendered Units and cash
deposited  by the  Sponsor to  purchase Securities or  cash held  in the Reserve
Account) and deducting  therefrom expenses  of the Trust,  Sponsor, counsel  and
taxes,  if any, any  remaining unpaid portion  of the Deferred  Sales Charge and
cash held for distribution to Unit Holders of record as of a date on or prior to
the evaluation;  and then  dividing the  resulting sum  by the  number of  Units
outstanding,  as of the date of such computation. In addition, after the initial
offering period, the Sponsor's Repurchase Price  will be reduced to reflect  the
Trust's  estimated  costs  of  liquidating  the  Securities  to  meet redemption
requests. There is no sales charge incurred when a Unit Holder sells Units  back
to  the Sponsor  other than the  payment of  the unpaid portion  of the Deferred
Sales Charge. Any Units repurchased by  the Sponsor at the Sponsor's  Repurchase
Price  may be reoffered to the public by  the Sponsor at the then current Public
Offering Price. Any profit or loss resulting from the resale of such Units  will
belong to the Sponsor.
 
    If  the supply of Units  exceeds demand (or for  any other business reason),
the Sponsor may, at any time,  occasionally, from time to time, or  permanently,
discontinue  the repurchase of Units of  this series at the Sponsor's Repurchase
Price. In such event, although under no obligation to do so, the Sponsor may, as
a service to Unit Holders, offer to repurchase Units at the "Redemption  Price".
Alternatively, Unit Holders may redeem their Units through the Trustee.
 
PROFIT OF SPONSOR
 
    The  Sponsor receives  a sales  charge on  Units sold  to the  public and to
dealers. The Sponsor may have  also realized a profit  (or sustained a loss)  on
the  deposit of the Securities in  the Trust representing the difference between
the cost of the Securities to the Sponsor and the cost of the Securities to  the
Trust  (for  a description  of  such profit  (or loss)  and  the amount  of such
difference  on  the  initial  Date  of  Deposit  see:  "Schedule  of   Portfolio
Securities").  The Sponsor may realize a  similar profit (or loss) in connection
with each additional deposit  of Securities. In addition,  the Sponsor may  have
acted  as  broker in  transactions relating  to the  purchase of  Securities for
deposit in the Trust. During the initial public offering period the Sponsor  may
realize  additional profit (or sustain a loss)  due to daily fluctuations in the
prices of the Securities in the Trust  and thus in the Public Offering Price  of
Units  received by the Sponsor.  Cash, if any, received  by the Sponsor from the
Unit Holders prior to the settlement date for purchase of Units or prior to  the
payment for Securities upon their delivery may be used in the Sponsor's business
and may be of benefit to the Sponsor.
 
    The Sponsor may also realize profits (or sustain losses) while maintaining a
secondary  market in  the Units,  in the  amount of  any difference  between the
prices at which  the Sponsor  buys Units  and the  prices at  which the  Sponsor
resells  such Units (such prices include a  sales charge) or the prices at which
the Sponsor redeems such Units, as the case may be.
 
                                       8
<PAGE>
VOLUME DISCOUNT
 
    Although under no obligation to do so, the Sponsor intends to permit  volume
purchasers of Units to purchase Units at a reduced sales charge. The Sponsor may
at  any time  change the  amount by which  the sales  charge is  reduced, or may
discontinue the discount altogether.
 
    The sales  charge of  2.90% of  the Public  Offering Price  will be  reduced
pursuant  to the following graduated  scale for sales to  any person of at least
$25,000 during the Initial  Offering Period. The sales  charge in the  secondary
market,  which  will  be  reduced pursuant  to  the  following  graduated scale,
consists of an Initial Sales Charge  and the remaining portions of the  Deferred
Sales  Charge. The  reductions indicated  will be  applied to  the Initial Sales
Charge.

    The reduced sales  charges as shown  on the  chart above will  apply to  all
purchases  of Units of this Trust on any one day by the same person, partnership
or corporation (other than a dealer), in the amounts stated herein.
 
    Units held  in the  name of  the  purchaser's spouse  or in  the name  of  a
purchaser's  child under  the age 21  are deemed  for the purposes  hereof to be
registered in the  name of  the purchaser. The  reduced sales  charges are  also
applicable  to  a  trustee  or  other  fiduciary,  including  a  partnership  or
corporation purchasing  Units for  a  single trust  estate or  single  fiduciary
account.
 
    The dealer concession will be 70% of the sales charge per Unit.
 
                                   REDEMPTION
 
RIGHT OF REDEMPTION
 
    One  or  more Units  represented by  a  Certificate may  be redeemed  at the
Redemption Price upon  tender of  such Certificate to  the Trustee  at its  unit
investment  trust  office  in  the  City  of  New  York,  properly  endorsed  or
accompanied by a  written instrument  of transfer  in form  satisfactory to  the
Trustee  (as set forth in  the Certificate), and executed  by the Unit Holder or
its authorized attorney. A  Unit Holder may tender  its Units for redemption  at
any  time after the settlement date for purchase, whether or not it has received
a definitive Certificate.  The Redemption Price  per Unit is  calculated as  set
forth under "Computation of Redemption Price". There is no sales charge incurred
when  a Unit Holder tenders  its Units to the  Trustee for redemption other than
the payment of any Deferred Sales Charge then due.
 
    On  the  third  business  day  following  the  tender  to  the  Trustee   of
Certificates  representing Units to be redeemed the Unit Holder will be entitled
to receive monies per Unit equal to the Redemption Price per Unit as  determined
by the Trustee as of the Evaluation Time on the date of tender.
 
                                       9
<PAGE>
    During  the period  in which  the Sponsor  maintains a  secondary market for
Units, the Sponsor may repurchase any  Unit presented for tender to the  Trustee
for  redemption no  later than the  close of  business on the  next Business Day
following such presentation.
 
    Units will be redeemed by the Trustee solely in cash for any one Unit Holder
tendering less than 2,500 Units.  With respect to redemption requests  regarding
at  least 2,500 Units, the  Sponsor may determine, in  its discretion, to direct
the Trustee to redeem  Units "in kind" by  distributing Portfolio Securities  to
the  redeeming Unit Holder. The  Sponsor may direct the  Trustee to redeem Units
"in kind" even  if it is  then maintaining a  secondary market in  Units of  the
Trust.  Unit Holders  redeeming "in  kind" will receive  an amount  and value of
Trust Securities per Unit equal to  the Redemption Price Per Unit as  determined
as  of the Evaluation Time  next following the tender  as set forth herein under
"Computation  of  Redemption  Price"  below.  The  distribution  "in  kind"  for
redemption  of Units  will be held  by the Trustee  for the account  of, and for
disposition in accordance with the  instructions of, the tendering Unit  Holder.
The  tendering Unit Holder will  be entitled to receive  whole shares of each of
the underlying Portfolio Securities,  plus cash equal to  the Unit Holder's  pro
rata  share of the  cash balance of  the Income and  Principal Accounts and cash
from the  Principal  Account  equal  to the  fractional  shares  to  which  such
tendering  Unit Holder is entitled. The Trustee, in connection with implementing
the redemption "in  kind" procedures  outlined above, may  make any  adjustments
necessary  to reflect differences between the  Redemption Price of Units and the
value of the Securities distributed "in kind"  as of the date of tender. If  the
Principal Account does not contain amounts sufficient to cover the required cash
distribution  to the  tendering Unit  Holder, the  Trustee is  empowered to sell
Securities in the Trust Portfolio in  the manner discussed below. A Unit  Holder
receiving  redemption distributions of Securities  "in kind" may incur brokerage
costs and odd-lot charges  in converting Securities so  received into cash.  The
Trustee will assess transfer charges to Unit Holders taking Securities "in kind"
according to its usual practice.
 
    The  portion  of the  Redemption Price  which  represents the  Unit Holder's
interest in the Income Account shall be withdrawn from the Income Account to the
extent available.  The  balance  paid on  any  redemption,  including  dividends
receivable  on  stocks trading  ex-dividend,  if any,  shall  be drawn  from the
Principal Account to the extent that  funds are available for such purpose.  The
Trustee  is authorized by the  Agreement to sell Securities  in order to provide
funds for redemption. To the extent Securities are sold, the size and  diversity
of  the Trust  will be  reduced. Such  sales may  be required  at the  time when
Securities would not  otherwise be sold  and might result  in lower prices  than
might  otherwise be realized. The Redemption  Price received by a tendering Unit
Holder may be more or less than the purchase price originally paid by such  Unit
Holder, depending on the value of the Securities in the Portfolio at the time of
redemption.  Moreover, due to  the minimum lot  size in which  Securities may be
required to be sold, the proceeds of such sales may exceed the amount  necessary
for payment of Units redeemed. Such excess proceeds will be distributed pro rata
to all remaining Unit Holders of record on the next following Record Date.
 
    Securities  to be sold for purposes of redeeming Units will be selected from
a list supplied by the Sponsor. If not so instructed by the Sponsor, the Trustee
will select  the  Securities  to be  sold  so  as to  maintain,  as  closely  as
practicable, the proportionate relationship between the number of shares of each
Security in the Trust.
 
COMPUTATION OF REDEMPTION PRICE
 
    The Trust Evaluation per Unit is determined as of the Evaluation Time stated
under "Summary of Essential Information" above and (a) semiannually, on the last
Business Day of each of the months of June and December, (b) on the day on which
any  Unit of the Trust  is tendered for redemption  (unless tender is made after
the Evaluation Time on such  day, in which case Tender  shall be deemed to  have
been  made  on the  next  day subsequent  thereto on  which  the New  York Stock
Exchange is open for trading) and (c)  on any other Business Day desired by  the
Sponsor or the Trustee, (1) by adding:
 
        a.  The aggregate value of Securities in the Trust, as determined by the
    Trustee;
 
                                       10
<PAGE>
        b.   Cash on hand in the Trust, including dividends receivable on stocks
    trading ex-dividend, other  than money deposited  to purchase Securities  or
    money credited to the Reserve Account;
 
        c.  All other assets of the Trust.
 
    (2)  and then, by deducting from  the resulting figure: amounts representing
any applicable  taxes or  governmental  charges payable  by  the Trust  for  the
purpose  of  making  an addition  to  the  reserve account  (as  defined  in the
Agreement, the "Reserve Account"),  amounts representing estimated accrued  fees
and  expenses  of the  Trust (including  legal  and auditing  expenses), amounts
representing unpaid fees of the Trustee, the Sponsor and counsel, any  remaining
unpaid  portion of the Deferred Sales Charge  and monies held to redeem tendered
Units and for  distribution to Unit  Holders of  record as of  the Business  Day
prior  to the  Evaluation being made  on the days  or dates set  forth above and
then;
 
    (3) by dividing the result of the  above computation by the total number  of
Units  outstanding on the  date of such Evaluation.  The resulting figure equals
the Redemption Price for each Unit.
 
    In addition, after the initial offering period, the Redemption Price will be
reduced to reflect the Trust's estimated costs of liquidating the Securities  to
meet the redemption.
 
    The  aggregate value of the Securities shall be determined by the Trustee in
good faith in the following manner: If the Securities are listed on one or  more
national  securities exchanges,  such valuation  shall be  based on  the closing
price on such Exchange which  is the principal market  thereof deemed to be  the
New York Stock Exchange if the Securities are listed thereon (unless the Trustee
deems  such price inappropriate as a basis for valuation). If the Securities are
not so listed, or, if so listed and the principal market therefor is other  than
such  exchange or  there is  no closing price  on such  exchange, such valuation
shall be based on the closing  price in the over-the-counter market (unless  the
Trustee  deems such price inappropriate as a basis for valuation) or if there is
no such closing price, by any of  the following methods which the Trustee  deems
appropriate:  (i)  on the  basis of  current  bid prices  of such  Securities as
obtained from  investment  dealers  or brokers  (including  the  Depositor)  who
customarily deal in securities comparable to those held by the Trust, or (ii) if
bid  prices are not  available for any of  such Securities, on  the basis of bid
prices for comparable  securities, or  (iii) by appraisal  of the  value of  the
Securities on the bid side of the market or by such other appraisal as is deemed
appropriate, or (iv) by any combination of the above.
 
POSTPONEMENT OF REDEMPTION
 
    The right of redemption may be suspended and payment of the Redemption Price
per Unit postponed for more than seven calendar days following a tender of Units
for redemption (i) for any period during which the New York Stock Exchange, Inc.
is  closed, other than for  customary weekend and holiday  closings, or (ii) for
any  period  during  which,  as  determined  by  the  Securities  and   Exchange
Commission, either trading on the New York Stock Exchange, Inc. is restricted or
an  emergency  exists  as  a  result of  which  disposal  or  evaluation  of the
Securities is not reasonably practicable, or (iii) for such other periods as the
Securities and  Exchange Commission  may by  order permit.  The Trustee  is  not
liable  to any person or in any way for  any loss or damage that may result from
any such suspension or postponement.
 
                                EXCHANGE OPTION
 
    Unit Holders of any Dean Witter Select Trust or any holders of units of  any
other  unit investment trust (collectively, "Holders") may elect to exchange any
or all of their units for units of one or more of any series of the Dean  Witter
Select  Equity Trust or for  units of any other  Dean Witter Select Trusts, that
may from time to time  be made available for such  exchange by the Sponsor  (the
"Exchange  Trusts"). Such an  exchange is implemented  by a sale  of Units and a
purchase of the units of an Exchange Trust. Such
 
                                       11
<PAGE>
units may be acquired  at prices based  on reduced sales  charges per unit.  The
purpose  of such reduced sales charge is to permit the Sponsor to pass on to the
Holder who  wishes  to exchange  units  the  cost savings  resulting  from  such
exchange. The cost savings result from reductions in time and expense related to
advice,  financial planning  and operational  expense required  for the Exchange
Option. The following Exchange Trusts  are currently available: the Dean  Witter
Select Municipal Trust, the Dean Witter Select Government Trust, the Dean Witter
Select Equity Trust, the Dean Witter Select Investment Trust and the Dean Witter
Select Corporate Trust.
 
    Each  Exchange Trust  has different  investment objectives:  a Holder should
read the Prospectus for the applicable Exchange Trust carefully to determine the
investment objective prior to exercise of this option.
 
    This option will  be available  provided the Sponsor  maintains a  secondary
market  in units of the applicable Exchange Trust and provided that units of the
applicable Exchange Trust are available for sale and are lawfully qualified  for
sale  in the state in which the Holder  is a resident. While it is the Sponsor's
present intention  to maintain  a secondary  market for  the units  of  Exchange
Trusts,  there is  no obligation on  its part to  do so. Therefore,  there is no
assurance that a market for units will in fact exist on any given date in  which
a  Holder wishes to sell or exchange Units; thus, there is no assurance that the
Exchange Option will be available to  any Unit Holder. The Sponsor reserves  the
right  to modify, suspend  or terminate this  option. Sixty days  notice will be
given prior to the  date of the  termination of or a  material amendment to  the
Exchange  Option except  that no notice  need be given  in certain circumstances
approved by the Securities  and Exchange Commission. In  the event the  Exchange
Option  is not available to a Unit Holder at the time such Unit Holder wishes to
exercise such option, the Unit Holder will be immediately notified and no action
will be taken with  respect to such tendered  Units without further  instruction
from the Unit Holder.
 
    Exchanges will be affected in whole units only. Any excess proceeds from the
surrender of a Unit Holder's Units will be returned. Alternatively, Unit Holders
will  be permitted to make up any difference between the amount representing the
Units being submitted for exchange and  the amount representing the units  being
acquired up to the next highest number of whole units.
 
    An  exchange  of Units  pursuant to  the Exchange  Option will  constitute a
"taxable event" under the Code, i.e., a Holder will recognize a gain or loss  at
the  time of exchange, except  that, upon an exchange of  Units for units of any
series of the Exchange Trusts which  are grantor trusts for U.S. federal  income
tax purposes the Internal Revenue Service may seek to disallow any loss incurred
upon  such exchange to the  extent that the underlying  securities in each Trust
are substantially identical and the purchase  of the units of an Exchange  Trust
takes  place less than thirty-one days after the  sale of the Units. In order to
avoid the potential disallowance of losses  for tax purposes, a Unit Holder  may
notify  the  Sponsor that  the  Unit Holder  desires  to purchase  units  of the
Exchange Trust on the thirty-first  day after the day of  the sale of the  Units
exchanged.  The proceeds of the Units surrendered  will be deposited in the Unit
Holder's brokerage account at the Sponsor and may be withdrawn at any time. Cash
from the account will be utilized to purchase units of the Exchange Trust on the
thirty-first day after the day of sale of the Units exchanged in accordance with
the procedures set forth above. A Unit  Holder may revoke the order to  purchase
at  any  time prior  to  the purchase  on the  thirty-first  day by  calling his
financial advisor. Units will be purchased at  a price based upon the net  asset
value  per unit plus the applicable sales  charge of 2.0%. However, there can be
no assurance that a market for units will exist on such date or that units  will
be  available for purchase on  such date. If units  are unavailable, the Sponsor
may acquire units in the  secondary market or create  units as soon as  possible
thereafter, which units will be sold by the Sponsor based on the net asset value
on  the date of purchase of the units  plus the applicable sales charge of 2.0%.
The order does not create  a contract or option to  acquire units. If units  are
not  held in the Sponsor's inventory on the  31st day or if the Sponsor does not
create additional units or is unable  to acquire units in the secondary  market,
units  of the Exchange Trust  will not be purchased and  the cash will remain in
the Unit Holder's account. A  Unit Holder who exchanges  Units of one Trust  for
units  of another  Trust should  consult his  or her  tax advisor  regarding the
extent to which such exchange results in  the recognition of a loss for  Federal
and/or state or local income tax purposes.
 
                                       12
<PAGE>
    To  exercise the Exchange Option, a Unit Holder should notify the Sponsor of
the desire to  acquire units of  one or more  of the Exchange  Trusts. Upon  the
exchange  of  Units of  the Trust,  any  Deferred Sales  Charge balance  will be
deducted from  the exchange  proceeds. If  units of  the applicable  outstanding
series  of the  Exchange Trust  are at  that time  available for  sale, the Unit
Holder may select the series  or group of series for  which the Units are to  be
exchanged.  The  Unit  Holder will  be  provided  with a  current  prospectus or
prospectuses relating to each series in which interest is indicated.
 
   
    The exchange transaction will operate  in a manner essentially identical  to
any  secondary market  transaction, i.e., Units  will be repurchased  at a price
based upon the aggregate bid side evaluation  per Unit of the Securities in  the
Portfolio.  Units of  the Exchange Trust  will be sold  to the Unit  Holder at a
price equal to the net asset value based on the offering or bid side  evaluation
(as  applicable) per unit  of the securities in  the Exchange Trust's Portfolio,
plus accrued interest, if any,  and the applicable sales  charge of 2.0% of  the
Public Offering Price per Unit. If the Exchange Trust is a series of Dean Witter
Select  Equity Trust, Select 10 Industrial Portfolio Series the applicable sales
charge on such Trust will be the  Deferred Sales Charge of such Trust which  may
be more or less than 2.0% of the Public Offering Price.
    
 
                                 DIRECT INVEST
 
   
    The  Sponsor has established Direct Invest, an automatic investment program.
Unit Holders may subscribe to Direct Invest by completing the Direct Invest plan
application. Pursuant to  the program, a  Unit Holder may  have any amount  from
$100   to  $5,000  debited  from  a  designated  bank  account  and  transferred
automatically, on a semi-monthly, monthly or quarterly basis, to The Bank of New
York for investment in Units of the  Trust. In lieu of issuing certificates  for
such  Units, The Bank of New York will  credit to the account of each individual
Unit Holder  the number  of Units  (including fractional  Units) purchased.  The
Sponsor intends, although under no obligation, to offer a new series of the Dean
Witter  Select Equity  Trust, Select 10  Industrial Portfolio  every three month
period. As each new  series is created,  Units of each such  new series will  be
automatically   purchased  under  the  Direct  Invest  program  subject  to  the
applicable sales charge for such series  as disclosed in the prospectus for  the
series.  A  prospectus  for  each new  series  will  be sent  to  a  Unit Holder
participating in  the program.  The Unit  Holder is  also eligible  to elect  to
invest  the distributions receivable from units of a trust about to terminate in
units of a New Series  as set forth in the  Direct Invest application. See  also
"Termination--The Rollover Option". Units of such New Series, the terms of which
will  be substantially the same  as the terms of  the terminating trust, will be
subject only to the  deferred sales charge. Distributions  during the life of  a
Trust  with respect  to Units purchased  through Direct  Invest (including Units
acquired through the rollover of such Units) will be automatically reinvested in
additional Units of such Trust (including fractional Units) subject only to  any
remaining portions of the Deferred Sales Charge.
    
 
   
    Unit  Holders, at any  time, may terminate  the automatic bank  debit of the
Direct Invest program  by so notifying  The Bank  of New York  or their  account
executive.  The program may be terminated or  changed by the Sponsor at any time
without notice. Unit Holders investing through an IRA or other pension plan  may
be limited in the amount that may be invested in a trust in any one year.
    
 
                              REINVESTMENT PROGRAM
 
    Unit Holders may elect to have the distributions with respect to their Units
automatically  reinvested in additional  Units of the Trust  subject only to any
remaining portions of  the Deferred  Sales Charge. (Reinvestment  Units are  not
subject  to the Initial  Sales Charge.) The  Unit Holder may  participate in the
Trust's reinvestment  program  (the "Program")  by  filing with  the  Trustee  a
written  notice of election.  The Unit Holder's completed  notice of election to
participate in the Program  must be received  by the Trustee  at least ten  days
prior to the Record Date applicable to any distribution in order for the Program
to be in effect as to such distribution. Elections may be modified or revoked on
similar notice.
 
                                       13
<PAGE>
    Such  distributions, to the extent reinvested in  the Trust, will be used by
the Trustee at  the direction of  the Sponsor in  one or both  of the  following
manners.  (i) The distributions may be used  by the Trustee to purchase Units of
this Series of  the Trust held  in the Sponsor's  inventory. The purchase  price
payable  by the Trustee for  each of such Units will  be equal to the applicable
Trust evaluation  per Unit  on  (or as  soon as  possible  after) the  close  of
business on the Distribution Date. The Units so purchased by the Trustee will be
issued or credited to the accounts of Unit Holders participating in the Program.
(ii)  If there are no Units in the Sponsor's inventory, the Sponsor may purchase
additional Securities for deposit  into the Trust  (as described in  "Prospectus
Part  B--Introduction.") The additional Securities  with any necessary cash will
be deposited by  the Sponsor with  the Trustee  in exchange for  new Units.  The
distributions may then be used by the Trustee to purchase the new Units from the
Sponsor.  The price for such  new Units will be  the applicable Trust evaluation
per Unit  on (or  as  soon as  possible  after) the  close  of business  on  the
Distribution  Date. (See "Public Offering of Units--Public Offering Price.") The
Units so purchased by the Trustee will be issued or credited to the accounts  of
Unit Holders participating in the Program. The Sponsor may terminate the Program
if  it does not have sufficient Units in its inventory or it is no longer deemed
practical to create additional Units.
 
    No fractional Units will  be issued under any  circumstances. If, after  the
maximum  number of  full Units  has been  issued or  credited at  the applicable
price, there remains a  portion of the distribution  which is not sufficient  to
purchase  a full Unit  at such price,  the Trustee will  distribute such cash to
Unit Holders. The cost of administering  the reinvestment program will be  borne
by the Trust and thus will be borne indirectly by all Unit Holders.
 
                             RIGHTS OF UNIT HOLDERS
 
UNIT HOLDERS
 
    A  Unit Holder  is deemed to  be a beneficiary  of the Trust  created by the
Indenture and Agreement  and vested with  all right, title  and interest in  the
Trust  created therein. A Unit Holder may  at any time tender its Certificate to
the Trustee for redemption.
 
    Ownership of Units  is evidenced  by registered  Certificates of  Beneficial
Interest  issued  in denominations  of one  or  more Units  and executed  by the
Trustee and the Sponsor. These Certificates are transferable or  interchangeable
upon  presentation at the unit investment  trust office of the Trustee, properly
endorsed or accompanied by an instrument of transfer satisfactory to the Trustee
and executed by the  Unit Holder or its  authorized attorney, together with  the
payment  of $2.00, if  required by the Trustee,  or such other  amount as may be
determined by the  Trustee and approved  by the  Sponsor, and any  other tax  or
governmental  charge imposed upon the transfer of Certificates. The Trustee will
replace any  mutilated,  lost,  stolen  or  destroyed  Certificate  upon  proper
identification,  satisfactory  indemnity and  payment  of charges  incurred. Any
mutilated Certificate must  be presented  to the Trustee  before any  substitute
Certificate will be issued.
 
    Under  the terms and  conditions and at  such times as  are permitted by the
Trustee, Units may also be held in uncertificated form. The rights of any holder
of Units held in  uncertificated form shall  be the same as  those of any  other
Unit Holder.
 
CERTAIN LIMITATIONS
 
    The death or incapacity of any Unit Holder will not operate to terminate the
Trust  nor entitle  the legal  representatives or heirs  of such  Unit Holder to
claim an accounting or to take any other action or proceeding in any court for a
partition or winding up of the Trust.
 
    No Unit Holder shall have the right  to vote except with respect to  removal
of  the Trustee or amendment and termination of the Trust. (See: "Administration
of the Trust--Amendment" and  "Administration of the Trust--Termination".)  Unit
Holders  shall have no right  to control the operation  or administration of the
Trust in  any  manner,  except  upon  the  vote  of  51%  of  the  Unit  Holders
 
                                       14
<PAGE>
outstanding  at any time for purposes of  amendment, or termination of the Trust
or discharge of the Trustee, all as provided in the Agreement; however, no  Unit
Holder shall ever be under any liability to any third party for any action taken
by  the Trustee or Sponsor. Unit Holders will be unable to dispose of any of the
Securities in  the  Portfolio,  as such,  and  will  not be  able  to  vote  the
Securities.  The Trustee, as  holder of the  Securities, will have  the right to
vote all  of  the voting  Securities  held in  the  Trust, and  will  vote  such
Securities  in  accordance  with  the instructions  of  the  Sponsor,  if given,
otherwise the Trustee shall vote as it, in its sole discretion, shall determine.
 
                              EXPENSES AND CHARGES
 
EXPENSES
 
    All or a  portion of  the organizational  expenses and  charges incurred  in
connection  with  the  establishment of  the  Trust  including the  cost  of the
preparation, printing and execution of the Indenture, Registration Statement and
other documents relating to the Trust,  Federal and State registration fees  and
costs,  the initial  fees and  expenses of  the Trustee  and legal  and auditing
expenses will be paid  by the Trust  and amortized over the  life of the  Trust.
Historically,  the costs of establishing unit  investment trusts have been borne
by a  trust's sponsor.  Advertising and  selling expenses  will be  paid by  the
Sponsor at no cost to the Trust.
 
FEES
 
    The  Sponsor's fee, earned for portfolio supervisory services, is based upon
the largest  number of  Units  outstanding during  the computation  period.  The
Sponsor's  fee is as set forth in  "Summary of Essential Information" may exceed
the actual costs of providing portfolio supervisory services for this Trust, but
at no time will the total amount the Sponsor receives for portfolio  supervisory
services  rendered to all series  of the Dean Witter  Select Equity Trust in any
calendar year exceed the aggregate cost to it of supplying such services in such
year.
 
    Under the Indenture and Agreement for its services as Trustee and evaluator,
the Trustee receives the  fee set forth in  "Summary of Essential  Information".
Certain  regular expenses of  the Trust, including  certain mailing and printing
expenses, are borne by the Trust.
 
    The Sponsor's fee, the  Trustee's fees and the  Trust expenses accrue  daily
but  are  payable only  on  or before  each  Distribution Date  from  the Income
Account, to the  extent funds are  available and thereafter  from the  Principal
Account.  Any of such fees may be increased without approval of the Unit Holders
in proportion to increases under the classification "All Services Less Rent"  in
the  Consumer Price Index published by the United States Department of Labor or,
if no longer published, a similar index. The Trustee, pursuant to normal banking
procedures, also receives benefits to the extent that it holds funds on  deposit
in  various  non-interest  bearing  accounts  created  under  the  Indenture and
Agreement.
 
OTHER CHARGES
 
    The following additional charges are or may be incurred by the Trust as more
fully described in  the Indenture  and Agreement: (a)  fees of  the Trustee  for
extraordinary  services,  (b)  expenses  of  the  Trustee  (including  legal and
auditing expenses)  and  of  counsel  designated by  the  Sponsor,  (c)  various
governmental  charges, (d) expenses and costs of any action taken by the Trustee
to protect the  Trust and  the rights  and interests  of the  Unit Holders,  (e)
indemnification  of the Trustee for any  loss, liability or expenses incurred by
it in  the administration  of the  Trust without  gross negligence,  bad  faith,
wilful malfeasance or wilful misconduct on its part or reckless disregard of its
obligations  and  duties, (f)  indemnification of  the  Sponsor for  any losses,
liabilities and expenses
 
                                       15
<PAGE>
incurred in acting  as Sponsor or  Depositor under the  Agreement without  gross
negligence,  bad  faith, wilful  malfeasance  or wilful  misconduct  or reckless
disregard of its obligations and duties, (g) expenditures incurred in contacting
Unit Holders upon  termination of the  Trust, and (h)  brokerage commissions  or
charges incurred in connection with the purchase or sale of Securities.
 
    The fees and expenses set forth herein are payable out of the Trust and when
so paid by or owing to the Trustee are secured by a lien on the Trust. Dividends
on the Securities are expected to be sufficient to pay the estimated expenses of
the  Trust. If the balances in the Income and Principal Account are insufficient
to provide for amounts payable by the  Trust, the Trustee has the power to  sell
Securities  to pay such amounts. To the  extent Securities are sold, the size of
the Trust will be  reduced and the  proportions of the  types of Securities  may
change.  Such  sales might  be  required at  a  time when  Securities  would not
otherwise be  sold and  might result  in lower  prices than  might otherwise  be
realized.  Moreover, due  to the  minimum lot  size in  which Securities  may be
required to be sold, the proceeds of such sales may exceed the amount  necessary
for the payment of such fees and expenses.
 
                          ADMINISTRATION OF THE TRUST
 
RECORDS AND ACCOUNTS
 
    The  Trustee will keep records and accounts of all transactions of the Trust
at its unit investment trust  office at 101 Barclay  Street, New York, New  York
10286.  These  records and  accounts will  be available  for inspection  by Unit
Holders at  reasonable times  during  normal business  hours. The  Trustee  will
additionally keep on file for inspection by Unit Holders an executed copy of the
Indenture and Agreement together with a current list of the Securities then held
in  the Trust. In connection with the storage and handling of certain Securities
deposited in  the  Trust, the  Trustee  is authorized  to  use the  services  of
Depository  Trust  Company.  These  services would  include  safekeeping  of the
Securities, coupon-clipping,  computer  book-entry  transfer  and  institutional
delivery  services.  The Depository  Trust Company  is  a limited  purpose trust
company organized under the Banking  Law of the State of  New York, a member  of
the Federal Reserve System and a clearing agency registered under the Securities
Exchange Act of 1934.
 
DISTRIBUTION
 
    Dividends  payable to the Trust as a  holder of record of its Securities are
credited by the Trustee to an Income Account, as of the date on which the  Trust
is  entitled  to receive  such dividends.  Other  receipts, including  return of
investment and  gain  and  amounts  received upon  the  sale,  pursuant  to  the
Indenture  and Agreement, of rights to  purchase other Securities distributed in
respect of the Securities in the Portfolio, are credited to a Principal Account.
Any distribution for each Unit  Holder as of a Record  Date will be made on  the
next  following Distribution Date or shortly  thereafter and shall consist of an
amount approximately  equal to  the dividend  income per  Unit, after  deducting
estimated   expenses,  if  any,  plus  such  Holder's  pro  rata  share  of  the
distributable cash balance of the Principal Account. Proceeds received from  the
disposition  of any of the Securities which are not used for redemption of Units
will be held in the Principal Account to be distributed on the Distribution Date
following receipt  of such  proceeds.  No distribution  need  be made  from  the
Principal  Account  if the  balance therein  is  less than  $1.00 per  100 Units
outstanding. A Reserve Account may be created by the Trustee by withdrawing from
the Income or Principal Accounts,  from time to time,  such amounts as it  deems
requisite  to establish  a reserve for  any taxes or  other governmental charges
that may be payable out of the Trust.  Funds held by the Trustee in the  various
accounts created under the Indenture are non-interest bearing to Unit Holders.
 
    On  each Deferred Sales Charge Payment Date Securities will be sold pro rata
in an amount equal to $2.00 per 100  Units to pay the Deferred Sales Charge  and
the proceeds will be distributed to the Sponsor.
 
    The  Trustee will follow a policy  that it will place securities acquisition
or disposition transactions with a broker or dealer only if it expects to obtain
the most favorable prices and  executions of orders. Transactions in  securities
held in the Trust are generally
 
                                       16
<PAGE>
made  in brokerage  transactions (as distinguished  from principal transactions)
and the Sponsor may act as broker therein and receive commissions thereon if the
Trustee expects thereby to obtain the  most favorable prices and execution.  The
furnishing  of statistical and research information to the Trustee by any of the
securities  dealers  through  which  transactions  are  executed  will  not   be
considered in placing securities transactions.
 
PORTFOLIO SUPERVISION
 
    The original proportionate relationship between the number of shares of each
Security  in the  Trust will be  adjusted to  reflect the occurrence  of a stock
dividend, a stock split, merger, reorganization or a similar event which affects
the capital structure of the  issuer of a Security in  the Trust but which  does
not  affect the Trust's percentage ownership of  the common stock equity of such
issuer at  the time  of such  event. If  the Trust  receives the  securities  of
another  issuer as the result  of a merger or  reorganization of, or a spin-off,
split-off or  split-up by  the issuer  of a  Security included  in the  original
portfolio,  the  Trust may  hold those  securities as  if they  were one  of the
Securities  initially  deposited  and  adjust  the  proportionate   relationship
accordingly  for all future  subsequent deposits. The Portfolio  of the Trust is
not "managed" by the  Sponsor or the Trustee;  their activities described  below
are  governed  solely by  the  provisions of  the  Indenture and  Agreement. The
Sponsor may direct  the Trustee  to dispose of  Securities upon  failure of  the
issuer  of a Security in the Trust to declare or pay anticipated cash dividends,
institution of  certain  materially  adverse legal  proceedings,  default  under
certain  documents  materially  and adversely  affecting  future  declaration or
payment of dividends, or the occurrence  of other market or credit factors  that
in the opinion of the Sponsor would make the retention of such Securities in the
Trust  detrimental to the interests of the Unit Holders. The Sponsor will direct
the Trustee to  sell Securities to  pay portions of  the Deferred Sales  Charge.
Except  as otherwise discussed herein, the acquisition of any Securities for the
Trust other than  those initially  deposited and  deposited in  order to  create
additional  Units, is prohibited. The Sponsor  is authorized under the Indenture
to direct the  Trustee to  invest the  proceeds of  any sale  of Securities  not
required  for  the  redemption of  Units  in eligible  money  market instruments
selected by  the Sponsor  which  will include  only negotiable  certificates  of
deposit  or time  deposits of  domestic banks which  are members  of the Federal
Deposit Insurance Corporation and  which have, together  with their branches  or
subsidiaries,  more than $2 billion in total assets, except that certificates of
deposit or time  deposits of  smaller domestic banks  may be  held provided  the
deposit  does  not  exceed  the  insurance  coverage  on  the  instrument (which
currently is $100,000), and provided further that the Trust's aggregate  holding
of certificates of deposit or time deposits issued by the Trustee may not exceed
the  insurance coverage  of such  obligations and  U.S. Treasury  notes or bills
(which shall be held until the maturity thereof) each of which matures prior  to
the  earlier of the next  following Distribution Date or  90 days after receipt,
the principal thereof and interest thereon  (to the extent such interest is  not
used  to pay Trust  expenses) to be distributed  on the earlier  of the 90th day
after receipt or the next following Distribution Date.
 
    During the life  of the Trust,  the Sponsor, as  part of its  administrative
responsibilities, shall conduct reviews to determine whether or not to recommend
the  disposition  of Securities.  In addition,  the  Sponsor shall  undertake to
perform such other reviews and procedures as it may deem necessary in order  for
it to give the consents and directions, including directions as to voting on the
underlying  Securities,  required  by  the  Indenture  and  Agreement.  For  the
administrative services performed in making such recommendations and giving such
consents and directions,  and in  making the  reviews called  for in  connection
therewith  the Sponsor shall  receive the portfolio  supervisory fee referred to
under "Summary of Essential Information".
 
VOTING OF THE PORTFOLIO SECURITIES
 
    Pursuant to the Indenture and Agreement,  voting rights with respect to  the
Portfolio  Securities and Replacement  Securities, if any,  will be exercised by
the Trustee in  accordance with  the Indenture or  the directions  given by  the
Sponsor.
 
                                       17
<PAGE>
REPORTS TO UNIT HOLDERS
 
    With each distribution, the Trustee will furnish to Unit Holders a statement
of  the amount of income and  other receipts distributed, including the proceeds
of the sale  of the  Securities (including  the sale  of any  Securities to  pay
portions  of the  Deferred Sales  Charge), expressed  in each  case as  a dollar
amount per Unit.
 
    Within a  reasonable period  of time  after the  last Business  Day in  each
calendar  year, but not later than February 15, the Trustee will furnish to each
person who at any time during such calendar  year was a Unit Holder of record  a
statement setting forth:
 
        1.  As to the Income and Principal Account:
 
           (a) the amount of income received on the Securities;
 
           (b) the amount paid for redemption of Units;
 
           (c)  the  deductions  for  applicable  taxes  or  other  governmental
       charges, if any, and  fees and expenses of  the Sponsor, the Trustee  and
       counsel;
 
           (d) the deductions of portions of the Deferred Sales Charge;
 
           (e) the amounts distributed from the Income Account;
 
           (f)   any other amount credited  or deducted from the Income Account;
       and
 
           (g) the  net  amount remaining  after  such payments  and  deductions
       expressed  both as a total dollar amount  and as a dollar amount per Unit
       outstanding on the last business day of such calendar year.
 
        2.  The following information:
 
           (a) a list  of the Securities  as of  the last business  day of  such
       calendar year;
 
           (b)  the number of Units  outstanding as of the  last business day of
       such calendar year;
 
           (c) the Unit Value  (as defined in the  Agreement) based on the  last
       Evaluation made during such calendar year; and
 
           (d)  the amounts actually distributed  during such calendar year from
       the Income and Principal Accounts,  separately stated, expressed both  as
       total  dollar amounts and  as dollar amounts per  Unit outstanding on the
       Record Dates for such distributions.
 
AMENDMENT
 
    The Indenture and Agreement may be amended from time to time by the  Trustee
and  the Sponsor or their  respective successors, without the  consent of any of
the Unit Holders  (a) to  cure any  ambiguity or  to correct  or supplement  any
provision  contained therein  which may  be defective  or inconsistent  with any
other provision contained therein; (b) to change any provision thereof as may be
required by the Securities and Exchange Commission or any successor governmental
agency exercising similar  authority; or  (c) to  make such  other provision  in
regard  to matters or questions arising thereunder as shall not adversely affect
the interest of the Unit Holders; provided, that the Indenture and Agreement may
also be amended from time to time by the parties thereto (or the performance  of
any  of the provisions of  this Indenture and Agreement  may be waived) with the
expressed written consent  of Unit Holders  evidencing 51% of  the Units at  the
time outstanding under the Indenture and Agreement for the purpose of adding any
provisions  to or changing in any manner or eliminating any of the provisions of
the Indenture and Agreement or of
 
                                       18
<PAGE>
modifying in  any manner  the  rights of  the  Unit Holders;  provided,  further
however,  that  the Indenture  and Agreement  may  not be  amended (nor  may any
provision thereof be waived) so as to (1) increase the number of Units  issuable
in  respect of the Trust above the aggregate  number specified in Part II of the
Agreement or such lesser  amount as may  be outstanding at  any time during  the
term  of  the  Indenture except  as  the  result of  the  deposit  of Additional
Securities, as therein provided, or reduce the relative interest in the Trust of
any Unit  Holder without  his consent,  (2) permit  the deposit  or  acquisition
thereunder  of  securities  or  other  property  either  in  addition  to  or in
substitution for any  of the Securities  except in the  manner permitted by  the
Trust  Indenture as in effect on the date  of the first deposit of Securities or
permit  the  Trustee  to  engage  in  business  or  investment  activities   not
specifically  authorized in the Indenture and Agreement as originally adopted or
(3) adversely affect the  characterization of the Trust  as a grantor trust  for
federal income tax purposes.
 
TERMINATION
 
    The  Indenture  and Agreement  provides that  the  Trust will  be liquidated
during  the  Liquidation  Period  as  set  forth  under  "Summary  of  Essential
Information"  and terminated  at the  end of  such period.  Additionally, if the
value of the Trust as shown by  any Evaluation is less than forty percent  (40%)
of the value of the Securities deposited in the Trust on the Date of Deposit and
thereafter,  the Trustee will, if directed  by the Sponsor in writing, terminate
the Trust. The Trust may also be  terminated at any time by the written  consent
of  Unit Holders owning 51% or more  of the Units then outstanding. Unit Holders
will receive their final  distributions (that is,  their pro rata  distributions
realized from the sale of Portfolio Securities plus any other Trust assets, less
Trust   expenses)  according  to  their   Election  Instructions.  The  Election
Instructions will  provide  for the  following  distribution options:  (1)  cash
distributions;  (2) distributions  "in kind" available  only to  any Unit Holder
owning at least 2,500 Units; or (3) to invest the distributions attributable  to
the Unit Holder in units of a subsequent series of the Dean Witter Select Equity
Trust  as designated  by the Sponsor  (the "New  Series") if such  New Series is
offered at such  time (the "Rollover  Option"). Unit Holders  who do not  tender
properly  completed Election Instructions to the  Trustee will be deemed to have
elected a cash distribution.
 
    CASH OR "IN KIND" DISTRIBUTIONS. Unit Holders holding less than 2,500  Units
will  receive distributions in  respect of their Units  at termination solely in
cash. Unit Holders holding at least 2,500 Units may indicate to the Trustee that
they wish to receive  termination distributions "in kind",  by returning to  the
Trustee  properly completed Election Instructions  distributed by the Trustee to
such Unit Holders of record 45 days  prior to the Termination Date. The  Trustee
will  duly honor such  election instructions received  on or before  the In Kind
Distribution Date. Such Unit Holder will be entitled to receive whole shares  of
each  of the underlying Portfolio Securities and cash from the Principal Account
equal to the fractional shares to which such tendering Unit Holder is  entitled.
A  Unit  Holder  receiving  distributions  of  Securities  "in  kind"  may incur
brokerage and odd-lot costs in converting Securities so received into cash.  The
Trustee  will transfer the Securities to be delivered in kind to the account of,
and for disposition in accordance with the instructions of, the Unit Holder.
 
    THE ROLLOVER OPTION.  A Unit Holder  may elect to  invest the  distributions
attributable  to the Unit  Holder in units of  a New Series  subject only to the
deferred sales charge of the  New Series. It is expected  that the terms of  the
New Series will be substantially the same as the terms of the Trust described in
this  Prospectus, and that similar  options in a subsequent  series of the Trust
will occur in each New Series of the Trust approximately one year after that New
Series' creation.  The  availability  of  this  option  does  not  constitute  a
solicitation  of  an  offer to  purchase  Units of  a  New Series  or  any other
security. A Unit Holder's election to participate in this option will be treated
as an indication of interest only. At any time prior to the purchase by the Unit
Holder of units  of a New  Series, such  Unit Holder may  change his  investment
strategy and receive, in cash, the proceeds of the sale of the Securities.
 
    METHOD  OF SECURITIES DISPOSAL. The Trustee will begin to sell the remaining
Securities held in  the Trust  on the next  business day  following the  In-Kind
Date.  Since the Trust is not managed,  Securities in the Portfolio must be sold
in accordance with the Indenture, which provides for sales over a period of days
or on  any one  day during  the Liquidation  Period set  forth in  the  "Summary
 
                                       19
<PAGE>
of  Essential Information". Daily proceeds of  such sales will be deposited into
the Trust, will be held in a non-interest bearing account until distributed  and
will be of benefit to the Trustee. The sales of Portfolio Securities may tend to
depress  the  market prices  for such  Securities and  thus reduce  the proceeds
available to  Unit Holders.  The Sponsor  believes that  gradual liquidation  of
Securities  during  the Liquidation  Period may  mitigate negative  market price
consequences stemming from  the trading of  large volumes of  Securities over  a
short  period of time. There can be  no assurance, however, that such procedures
will effectively mitigate any adverse price consequences of heavy volume trading
or that such procedures will produce a better price for Unit Holders than  might
have been obtained had all the Securities been sold on one particular day during
the Liquidation Period.
 
    The Trustee will, after deduction of brokerage charges and costs incurred in
connection  with the sale of Securities, any  fees and expenses of the Trust and
payment into  the Reserve  Account of  any amount  required for  taxes or  other
governmental  charges that may be payable by  the Trust, distribute to each Unit
Holder, upon surrender for cancellation of  its Certificate after due notice  of
such  termination, such Unit Holder's pro rata share in the Income and Principal
Accounts. The sale of Securities in the  Trust upon termination may result in  a
lower  amount than might otherwise be realized if such sale were not required at
such time. For this reason, among others,  the amount realized by a Unit  Holder
upon termination may be less than the amount paid by such Unit Holder for Units.
 
    Section  17(a) of the Investment Company Act of 1940 restricts purchases and
sales between affiliates of registered investment companies and those companies.
Pursuant to  a recent  exemptive order,  each terminating  Select 10  Industrial
Portfolio  Series can now sell securities to the next Series if those securities
continue to  meet the  Select 10  Strategy by  remaining among  the ten  highest
dividend-yielding securities. The exemption will enable each Series to eliminate
commission  costs on these transactions. The  price for those securities will be
the closing sale price on the sale date on the exchange where the securities are
principally traded, as certified and confirmed by the Trustee of each Series.
 
                       RESIGNATION, REMOVAL AND LIABILITY
 
REGARDING THE TRUSTEE
 
    The Trustee shall be under no liability  for any action taken in good  faith
in reliance on prima facie properly executed documents or for the disposition of
monies  or  Securities  in  the  Trust,  nor  shall  the  Trustee  be  liable or
responsible in  any way  for depreciation  or  loss incurred  by reason  of  the
disposition  of any  Securities by  the Trustee.  However, the  Trustee shall be
liable for wilful misfeasance, bad faith or gross negligence in the  performance
of  its duties  or by reason  of its  reckless disregard of  its obligations and
duties under the  Indenture and  Agreement. In  the event  of a  failure of  the
Sponsor  to act, the Trustee may act under the Indenture and Agreement and shall
not be liable for any such action taken  by it in good faith. The Trustee  shall
not  be personally  liable for any  taxes or other  governmental charges imposed
upon the Trust  or in respect  of the  Securities or the  interest thereon.  The
Agreement also contains other customary provisions limiting the liability of the
Trustee  and providing for  the indemnification of  the Trustee for  any loss or
claim accruing to  it without  gross negligence, bad  faith, wilful  misconduct,
wilful misfeasance or reckless disregard of its duties and obligations under the
Agreement on its part.
 
    The  Trustee  or any  successor  may resign  by  executing an  instrument in
writing, filing the same with the Sponsor  and mailing a copy of such notice  of
resignation  to all Unit Holders then of  record. Upon receiving such notice the
Sponsor will use its  best efforts to appoint  a successor Trustee promptly.  If
the  Trustee becomes incapable of acting or  becomes bankrupt or its affairs are
taken over by public  authorities, or upon the  determination of the Sponsor  to
remove the Trustee for any reason, either with or without cause, the Sponsor may
remove  the Trustee  and appoint  a successor as  provided in  the Agreement. If
within 30 days of the resignation of  a Trustee no successor has been  appointed
or,  if appointed,  has not accepted  the appointment, the  retiring Trustee may
apply to a
 
                                       20
<PAGE>
court of  competent  jurisdiction  for  the  appointment  of  a  successor.  The
resignation  or removal of  a Trustee becomes effective  only when the successor
Trustee  accepts  its  appointment  as  such  or  when  a  court  of   competent
jurisdiction appoints a successor Trustee.
 
REGARDING THE SPONSOR
 
    The  Sponsor shall be under no liability to the Trust or to Unit Holders for
taking any action or for refraining from any action in good faith or for  errors
in  judgment. Nor  shall the  Sponsor be  liable or  responsible in  any way for
depreciation or loss incurred by reason of the disposition of any Security.  The
Sponsor  will,  however,  be  liable  for  its  own  wilful  misfeasance, wilful
misconduct, bad faith, gross negligence or reckless disregard of its duties  and
obligations under the Agreement.
 
    If at any time the Sponsor shall resign under the Agreement or shall fail or
be incapable of performing its duties thereunder or shall become bankrupt or its
affairs  are taken over by public authorities, the Agreement directs the Trustee
to either (1) appoint a successor  Sponsor or Sponsors at rates of  compensation
deemed  reasonable  by  the  Trustee not  exceeding  amounts  prescribed  by the
Securities and Exchange  Commission, or  (2) terminate the  Trust Indenture  and
Agreement  and  the Trust  and liquidate  the Trust.  The Trustee  will promptly
notify Unit Holders of any such action.

            This Reference Trust Agreement dated March 29, 1996

      such 90-day period or such earlier date as the Depositor

            C.    Article III, entitled "Administration of Trust",

                        "With respect to the Trust, the cost of the
                  preparation, printing and execution of the
                  Certificates, Indenture, Registration Statement
                  and other documents relating to the Trust,

                  extent not borne by the Sponsor, shall be paid
                  by the Trust;"

            D.    The third paragraph of Section 3.05 is hereby
      amended to add the following sentence after the first
      sentence thereof: "Depositor may direct the Trustee to
      invest the proceeds of any sale of Securities not required
      for the redemption of Units in eligible money market
      instruments selected by the Depositor which will include
      only negotiable certificates of deposit or time deposits
      of domestic banks which are members of the Federal Deposit
      Insurance Corporation and which have, together with their
      branches or subsidiaries, more than $2 billion in total
      assets, except that certificates of deposit or time
      deposits of smaller domestic banks may be held provided
      the deposit does not exceed the insurance coverage on the
      instrument (which currently is $100,000), and provided
      further that the Trust's aggregate holding of certificates
      of deposit or time deposits issued by the Trustee may not
      exceed the insurance coverage of such obligations and U.S.
      Treasury notes or bills (which shall be held until the
      maturity thereof) each of which matures prior to the

                                    -3-



      earlier of the next following Distribution Date or 90 days
      after receipt, the principal thereof and interest thereon
      (to the extent such interest is not used to pay Trust
      expenses) to be distributed on the earlier of the 90th day
      after receipt or the next following Distribution Date."

            E.  The first sentence of each of Sections 3.10, 3.11
      and 3.12 is amended to insert the following language at
      the beginning of such sentence, "Except as otherwise
      provided in Section 3.13,".

            F.  The following new Section 3.13 is added

            Section 3.13.  Extraordinary Event - Security
      Retention and Voting.  In the event the Trustee is
      notified of any action to be taken or proposed to be taken
      by holders of the securities held by the Trust in
      connection with any proposed merger, reorganization,
      spin-off, split-off or split-up by the issuer of stock or
      securities held in the Trust, the Trustee shall take such
      action or refrain from taking any action, as appropriate,
      so as to insure that the securities are voted as closely
      as possible in the same manner and in the same general
      proportion as are the securities held by owners other than
      the Trust.  If stock or securities are received by the
      Trustee, with or without cash, as a result of any merger,
      reorganization, spin-off, split-off or split-up by the
      issuer of stock or securities held in the Trust, the
      Trustee at the direction of the Depositor may retain such
      stock or securities in the Trust.  Neither the Depositor
      nor the Trustee shall be liable to any person for any
      action or failure to take action with respect to this
      section.

            G.    Section 1.01 is amended to add the following
      definition:  (9) "Deferred Sales Charge" shall mean any
      deferred sales charge payable in accordance with the
      provisions of Section 3.12 hereof, as set forth in the
      prospectus for a Trust.  Definitions following this
      definition (9) shall be renumbered.

            H.    Section 3.05 is hereby amended to add the
      following paragraph after the end thereof:  On each
      Deferred Sales Charge payment date set forth in the
      prospectus for a Trust, the Trustee shall pay the account
      created pursuant to Section 3.12 the amount of the
      Deferred Sales Charge payable on each such date as stated




<PAGE>

                                    -4-



      in the prospectus for a Trust.  Such amount shall be
      withdrawn from the Principal Account from the amounts
      therein designated for such purpose.

            I.    Section 3.06B(3) shall be amended by adding the
      following:  "and any Deferred Sales Charge paid".

            J.    Section 3.08 shall be amended by adding the
      following at the end thereof:  "In order to pay the
      Deferred Sales Charge, the Trustee shall sell or liquidate
      an amount of Securities at such time and from time to time
      and in such manner as the Depositor shall direct such that
      the proceeds of such sale or liquidation shall equal the
      amount required to be paid to the Depositor pursuant to
      the Deferred Sales Charge program as set forth in the
      prospectus for a Trust.

            K.    Section 3.12 shall be added as follows:

            Section 3.12. Deferred Sales Charge.  If the
      prospectus for a Trust specifies a Deferred Sales Charge,
      the Trustee shall, on the dates specified in and as
      permitted by the prospectus, withdraw from the Income
      Account if such account is designated in the prospectus as
      the source of the payments of the Deferred Sales Charge,
      or to the extent funds are not available in that account
      or if such account is not so designated, from the
      Principal Account, an amount per Unit specified in the
      prospectus and credit such amount to a special, non-Trust
      account maintained at the Trustee out of which the
      Deferred Sales Charge will be distributed to the
      Depositor.  If the Income Account is not designated as the
      source of the Deferred Sales Charge payment or if the
      balances in the Income and Principal Accounts are
      insufficient to make any such withdrawal, the Trustee
      shall, as directed by the Depositor, either advance funds,
      if so agreed to by the Trustee, in an amount equal to the
      proposed withdrawal and be entitled to reimbursement of
      such advance upon the deposit of additional monies in the
      Income Account or the Principal Account, sell Securities
      and credit the proceeds thereof to such special
      Depositor's account or credit Securities in kind to such
      special Depositor's Account.  Such directions shall
      identify the Securities, if any, to be sold or distributed
      in kind and shall contain, if the Trustee is directed by
      the Depositor to sell a Security, instructions as to
      execution of such sales.  If a Unit Holder redeems Units




<PAGE>

                                    -5-



      prior to full payment of the Deferred Sales Charge, the
      Trustee shall, if so provided in the prospectus, on the
      Redemption Date, withhold from the Redemption Price
      payment to such Unit Holder an amount equal to the unpaid
      portion of the Deferred Sales Charge and distribute such
      amount to such special Depositor's account or, if the
      Depositor shall purchase such Unit pursuant to the terms
      of Section 5.02 hereof, the Depositor shall pay the
      Redemption Price for such Unit less the unpaid portion of
      the Deferred Sales Charge.  The Depositor may at any time
      instruct the Trustee to distribute to the Depositor cash
      or Securities previously credited to the special
      Depositor's account.

                  -----------------------------------

Gentlemen:

            We have acted as special counsel for you as Depositor
of the Dean Witter Select Equity Trust, Select 10 Industrial
Portfolio 96-2 (the "Trust"), in connection with the issuance
under the Trust Indenture and Agreement, dated September 30,
1993, and the related Reference Trust Agreement, dated
March 29, 1996 (such Trust Indenture and Agreement and
Reference Trust Agreement collectively referred to as the
"Indenture"), between you, as Depositor, and The Bank of New
York, as Trustee, of units of fractional undivided interest in
said Trust (the "Units") comprising the Units of Dean Witter

            Based upon the foregoing, we advise you that, in our
opinion, when the Indenture has been duly executed and
delivered on behalf of the Depositor and the Trustee and when
the certificate evidencing the Units has been duly executed and
delivered by the Depositor and the Trustee in accordance with
the Indenture, the Units will be legally issued, fully paid and
nonassessable by the Trust, and will constitute valid and
binding obligations of the Trust and the Depositor in
accordance with their terms, except that enforceability of
certain provisions thereof may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other
similar laws affecting creditors generally and by general
equitable principles.

            We hereby consent to the filing of this opinion as an
exhibit to the Registration Statement (File No. 333-01235)
