the
TIMEX
Model
33
Movement
The
Model
33
movement
is
a 13 ligne serf-winding movement with
day
and
date
features. The
Model
33 utilizes the same basic construction
as
the
Model
31
except
that
a
day
and
date
mechanism has been added. A plane-
tary
gear
winding
system located on the Front Frame provides a compact
method
of
obtaining
the necessary
gear
reduction between the self-winding
weight
and
the mainspring.
The reserve
power
of
the mainspring when the watch
is
worn
by
a
normally
active person
is
sufficient
to
run the watch
for
a full
day.
The
day
and
date
mechanism
is
similar
to
that
used
in
the
Model
27.

The Model 33 movement is dis-
assembled as follows: Remove the
case
back . Loosen and remove two
Rotor Frame Screws (see figure 1 ).
Lift the rotor assembly slightly to
free the dowels. Since the Rocker
Arm fits between the Rotor Frame
and the Rotor Weight, position the
rotor weight as shown in figure 2
and slide the assembly along the
movement
plate (toward the bal-
ance wheel) until it is free of the
rocker
arm and then lift the assem-
bly out of the case.
CAUTION: Any attempt to lift the
weight before it is free of the
Rocker Arm
will result in damage to
the movement.
Pull crown
out into the set position.
Loosen the Set Lever Screw
and
raise lever sufficiently to release
the stem
and pull the crown and
stem assembly free of the move-
ment
and the case (see figure 2).
With tweezers, carefully remove

DATE RING INDEXING
A
tab on the underside of the Date
Wheel engages the Date Lever and
moves the Date Lever
tab backward
one tooth on the Date
Ring . At a
predetermined time (about mid-
night) the date lever
is released
and
moves the date ring forward
one space.
The Date Click Spring
engages the Date
Ring to prevent
backward motion when the Date
Lever
is being moved.
DAY DIAL INDEXING
A
tab on the upper side of the
Date Wheel engages the Day Dial
Pinion. Rotating the
Day Dial Pinion
moves the Day Dial

There is no need to remove the
Fl GURE 3 planetary gear assembly from the

The
Model 24 procedure for remov-
ing the balance, cleaning, lubricat-
ing and reassembling the balance
described on pages 24 .5, 24.6, and
24.7 should be followed for the
Model 33 movement.

FIGURE 4
To reassemble the
Model
33 movement into a watch
after
the basic
movement has been cleaned
and
oiled, the
following
procedure should
be
followed.
Refer to the
exploded
view
on Page 33.2 as a guide.
Assemble the Cannon Pinion Assembly
onto
the Center Post
of
the move-
ment.
Apply
a small amount
of
fine
watch
oil
to
the center hole in the
Cannon
Pinion. Assemble the
Hour
Wheel
and
Hour
Wheel
Washer
onto
the
Cannon
Pinion Assembly.
Remove the short Pillar Screw (if assembled)
and
the
long
Pillar Screw
from
the movement.
Be
sure the bushing is in place in the rocking
bar
and
then
po
sition the lubricated Date Frame Assembly on the movement
as shown
on
Page 33.2
and
in Figure
3.
Hold
Date
Frame assembly in
plac
e
and
check
proper
Date
Wheel
engagement
by
testing
with
tweezers.
Secure the
Date
Frame assembly
to
the movement
with
the
long
and
short
pillar
screws. Reengage the Rocking
Bar
spring
as shown in Figure 2.
Check
for
proper
engagement
and
function
of
the crown
and
stem
assembly. Rotate crown enough
to
move
finger
on
the
Date
Wheel
away
from
the
cut
out
at
the center post (
see
Page 33.4).
Position the
Date
Ring on the Date Frame
so
it
is
engaged
with
the
finger
on
the
Date
Lever
and
the Detent Spring.
Test the
lubricated
Day
Frame Assembly (see Page 33.6)
for
free
rotat
i
on
of
the
Day
Pinion against the
Day
Detent
Spring
.
Note
the
two
smafl
locating
holes, the boss
and
the cut
out
on the underside
of
the
Day
Frame Assembly
(see
center
view
on Page

lubricated
Day
Frame Assembly over the center
of
the movement
and
orient
the
assembly
on
the Date Ring
so
the
left
end
of
the cut
out
just clears the
tab
on the
Date
Lever.
Apply

Reassembly of Movement (Model 33)
Carefully orient the dial over the assembly and then, hold ing the dial
in place, turn the assembly over and bend the four tabs to secure the
dial to the Date Frame.
TO POSITION HANDS FOR PROPER DAY AND DATE CHANGE
First -Hold watch assembly with mov ement side up and crown and
stem at three o'clock position. Pull out crown and stem.
Next -Rotate crown and stem slowly and observe date lever at nine
o'clock position.
Date lever will then begin to move and a click
will be heard. After the click, rotate crown slowly until date
lever snaps back . At this time stop rotating .
Fi
nally-Turn assembly over and replace all hands at 12 o'clock position.
Check the
proper function of the bay and the Date change mechanism.
Loosen the set lever screw
and remove the crown and stem as previously
noted on page 33.3. Position the Dial
and Movement assembly in the
bezel, insert the crown
and stem through the bezel and retighten the
set lever screw.
Reassemble the Retaining Spring as shown in Figure
2. The end of the
spring should be inserted into the groove near the stem at the balance
wheel end of the movement. Insert the rest of the spring into the groove
being careful not to damage the balance ass embly .
Reassemble the
rotor assembly by sliding it into the movement under
the rocker arm as shown in Figure 2. Secure the rotor to the movement
with two screws as shown in Figure 1.
Position the case
back with the 'T' on "Timex" toward the crown and
snap it into the bezel.
