TIMEX IS AN EASY WATCH TO ADJUST AND REPAIR
rr MEANS BUSINESS — MORE BUSINESS — FOR YOU
lake any watch you may carry in your line, the Timex will
require occasiomd repairs and adjustments. As a matter of
fact, you will probably be called upon to repair and adjust
more Timex watches during the course of a day than any
other brand. After ah, more people buy Timex than any other
watch in the world. In the United States, alone, one out of
every three watches sold is a Timex.
Understandably, Timex owners will turn to you. The Timex
movement is very easy to repair. As a reputable jeweler in
your community, you are the logical man to do the job. They
know you. They have confidence in your ability. They appre
ciate your work. And, while these repairs and adjustments
may be of little imme^te value, they do offer you an un
usual opportunity to build store traffic — and make more
sales now and in the future.

SERVICING A TIMEX
MODELS 22, 29, 23
Already many million Timex watches are in service through
out the world and each year this quantity is rapidly increasing.
With so many in circulation, a large proportion of repairs taken
into jewelers will consist of Timex watches. An effective and
efficient repair service is essential, based on techniques formu
lated after many years of factory servicing.
Even with the most rugged of .watches, as with all mechan
ical devices, sometime it will require a servicing operation to
cover for mishandling, damage, oiling or wear, etc.
To present the Timex servicing procedure in as few words
as possible for persons who are already skilled in watch repair,
we have prepared a series of illustrative drawings showing those
areas in which you may need guidance.
Cases
The Timex waterproof, self wind and non-waterproof range
of watches all feature conventional designs of watch case with
which all jewelers are familiar.
As these styles change each year to meet changing tastes of
customers, detailed methods of uncasing are not shown. Although
styling changes, the basic method for casing and uncasing watches
remains the same.
It is important to note that every Timex, when completed
at the plant, is subjected to electronic timing tests and is run
tested in several positions, including horizontal and vertical posi
tions, to establish accurate timekeeping. In addition, all water
proof cases are individually tested to 35 pounds per square inch,
which is equivalent to immersion in water to a depth of 82 feet.

Every watch is dust protected by means of a dust seal which is
located around the winding stem. Sketches showing the various
types used are included in this service manual.
Every Timex is fi tted with a crystal which has been devel
oped to resist crazing and shrinkage.
Every watch has an unbreakable mainspring which gives a
consistent torque output and an average running time of 42 hours.
Movements
Illustrations show the Timex movement is of two plate
design, whereas most conventional watches feature the bridge
design.
The two plate design is most important as it ensures inter
changeable accuracy for gear train and escapement, no further
adjustment of escapement is necessary, the correct locking engage
ment between pallet pins and escape wheel is ensured, thereby
facilitating servicing.
The use of individual bridges may require selective fi tting
and special adjustments.
However, should it be necessary to completely dismantle
the movement, the illustrations in this booklet will guide further
servicing.
In the event that complete dismantling is required, it is
recommended that the front frame be removed, thus fully ex
posing the gear train and associated parts. To reassemble, start
with the back frame. Normal care should be exercised to ensure
proper location of the pivots in their respeaive hole positions
in the plates.
As described later, it is necessary only to remove the balance
wheel assembly, cannon pinion, ratchet wheel bridge, ratchet
wheel and click.

In the event that it is necessary to remove the pallet lever
and escape wheel, illustrations are included showing this opera
tion, indicating removal and replacement.
Timex has found through long and careful research the best
method of cleaning the movement is with only the forementioned
parts removed (i. e. with barrel and mainspring in place). The
cleaning method, while removing any contamination from the
movement will also remove oil from the train holes and bearings.
Since the mainspring is not capped, oil will also be removed from
this area and re-oiling is required.
In the case of the barrel, special holes are provided to ac
complish this. For the self-wind movement, it is essential that
oil be applied to the slipping tail of the mainspring to ensure
correa function.
It is seldom necessary to remove other parts except those
mentioned. However, these parts must always be removed for
movement cleaning.
Research and development are continually in progress, in
vestigating new materials, new processes, etc. As these new fea
tures become thoroughly tested under simulated long term fi eld
conditions, they will be introduced into the movement as part
of the Timex program, to ensure that latest technical develop
ments are incorporated in these products.

As stated previously, with only the balance assembly, cannon
pinion, ratchet wheel bridge, ratchet wheel and click removed
from the movement it is possible to clean thoroughly and effic
iently without further dismantling. For this purpose the use of
a cleaning machine is advantageous but not an absolute necessity.
The movement should be placed in the cleaning basket with
the front frame upwards to accomplish proper draining of fl uid
from mainspring barrel; it should be well swirled in the cleaning
fl uid after which at least two sets of rinsing fl uid should be used,
of which the final, especially, must be absolutely clean. The
movement then should be thoroughly dried.

If a cleaning machine is not available the same procedure
can be followed by holding the movement fi rmly around the
winding stem with a pair of tweezers and shaking it in the clean
ing and rinsing fl uids to ensure that they pass to all parts of
the movement.
The balance assembly should be cleaned in a small jar to
prevent damage to the hairspring. Only standard watch cleaning
fl uids should be used. It should be remembered that when re-
oiling the movement only high grade watch oil should be used
and carefully metered. (Oil used in factory assembly is Elgin
#M56B.) Before the balance assembly is replaced in a repaired
movement the balance cups should be oiled no less than % full.
Before replacing the cannon pinion, apply grease to the center
arbor.
MODEL 29 SELF WINDING ATTACHMENT
The Model 29 self winding watch uses the Model 22 move
ment, details of which have already been given. To this is added
the self winding attachment which winds the watch during the
time the watch is worn; when taken off the wrist of a normally
active person, the reserve power in the mainspring is sufficient
to run the watch for a full day.
In this booklet will be found sketches showing the follow
ing:
Plate XI) Completely exploded view of movement.
Plate XII) Oiling mainspring slipping tail.
When the Model 29 is cleaned as a movement, the main
spring and the mainspring slipping tail must be re-oiled to re
place the oil and grease washed away in cleaning.

The mainspring can be re-oiled through the two holes in
the back frame as perviously described and should be done with
the mainspring approximately half wound.
To introduce oil between the slipping tail and the inside of
the barrel, it is necessary to hold the movement at about 45°, the
barrel and front frame uppermost, and using an oiler, wipe oil
into the space between the outside diameter of the barrel and the
barrel sweeping in the back frame. This oil will work up between
the slipping tail and the inside of the barrel.
On later models one of the oil holes in the back frame has
been moved specifically to facilitate oiling of the slipping tail.
On models where it has been done, this can be clearly seen.
MODEL 23 MOVEMENT
6-3/4 X 8 LIGNE
This new miniaturized version of the Model 22 movement
is available in both men's and ladies' models. Basically the dis
mantling, cleaning and repairing of a Model 23 watch is similar
to that already shown for the Model 22. There are some design
features of the Model 23, however, which slightly alter the pro
cedure. This is shown on the descriptive drawings attached.
Plate XIII) Completely exploded view of movement.
Plate XrV) Changing crown and stem.
The movement may be cleaned after removal of the cannon
pinion, balance wheel, ratchet wheel bridge, ratchet wheel and
click.

USEFUL HINTS
1) Although it has been stated in an earlier page that
reassembly for the Model 22 movement should be carried out on
the back frame, it is possible to reverse the procedure for the
Model 23 movement and build the watch on the front frame,
held in a conventional jewelers assembly block.
2) Oiling. When oiling the front frame balance cup, to
facilitate the precise entry of the oil to the bottom of the cup, un
dertake this operation through the balance screw hole before
the balance screw is assembled.
3) A drop of oil applied to the stem wind pinion before
assembly will hold the pinion and its bridges together, thus
facilitating assembly.
USEFUL HINTS
MODEL 29 SELF WINDING ATTACHMENT
1) Examine the action of the rotor on the winding frame,
that the staking is secure and that the rotor is free to make
complete revolutions without interference against winding frame,
movement, winding stem, case spring and case. Check that the
case spring is properly located in the groove of the bezel.
2) Check the freeness of the bell crank lever and the
straight lever on the winding frame assembly; the freeness of the
rollers on these levers when they roll over the eccentric cam
on the rotor and the correct action of the two small clicks against
the winding ratchet wheel.
3) Check the action of the winding ratchet wheel. By each
revolution of the rotor, the winding ratchet wheel should be
moved forward approximately six teeth.
4) Check the action of the mainspring in the barrel, that
the mainspring tail is gripping properly in the lancing of the
sliding tail. The mainspring should have fi ve to six full turns
before the sliding tail starts to revolve in the barrel.
5) Oil all the moving parts of the winding attachment
sparingly.
