The TIME X® Model1 08 Movement
SHOWN ACTUAL S IZE
The Model108 movement is a 13 ligne self-wind movement featuring the Timex
"V-Conic ® " bearing system , two plate design and a fast change system for
setting the date . The Model108 contains a planetary gear self-winding system.
The
routine movement of the wrist of a normally active person is sufficient to
keep the watch running without manual winding.
The basic movement is similar to the Timex Model104.
The Timex code number appears on the edge of the diai. The code number
shows the catalog number, movement number, and year of manufacture for the
watch (see page 1.1 of the Timex Service Manual for explanation).

is
disassembled
as
follows
:
Remove the case back. Loosen and
remove
two
rotor
plate 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
assembly, posi-
tion

slicd
the
assembly
along
the
movement
plate, (toward the

until
it
is free of the
rocker
arm and
then
lift
the assembly
out
of
the
case.
CAUTION: Any
attempt
to

Loosen the set lever screw and raise

sufficiently to release the stem
and pull the Crown and Stem
Assembly free of the movement and
the case (see figure 3).
Some Timex self-wind watches are
designed so the Movement and Dial
Assembly is removed only through
the back of the case. This type of
watch can be identified by removing
the case back and checking for a re-
taining ring on the inside of the bezel
instead of the flange shown in
figure 1.
When watch has retaining ring,
do not try to remove the crystal.
Carefully free retaining ring from
case groove and remove. Movement
and Dial Assembly may then be
removed through the back of the
case.
When watch does not have retaining
ring, turn the assembly over and
remove crystal using a crystal
remover. The Reflector Ring and the
Movement and Dial Assembly can
then be removed through the front of
the bezel (see figure 4).

movement as
described
starting
on
page 108.8
Replace

is held
out
of
engagement
(through the hole in the Date Frame

With
the above
parts
removed, the
basic movement
of
the Model 108
may be cleaned and relubricated as
outlined
for
the
Model104
movement.
Other
metal parts may be cleaned in
the same manner as
the
movement.
CAUTION
Extreme care
must
be exercised in
cleaning
dials
and hands. Solvent
type cleaners
will
often
damage the

After the ba sic movement has been
cleaned,
lubricated and reassembled
as
outlined for the Model 104 move-
ment , the Model 108 movement
reassembly is completed as follows:
Apply grease (Moebius special lubri -
cant is used in the factory) to 3 points
on the Rotor Frame Assembly as
noted on
figure A. Apply grease to
Rotor cam (surface A) . Force grease
beneath
Rotor Staff Head (at B) and
underside of Rotor Cam (at C).
Assemble ratchet wheel and Date
Frame (see p 108.5) and
secure with
screw. Rotate crown until mainspring
and slip tail are positioned as noted
on figure B. Apply drop of spreading
type oil (Woods
AAAA oil is used in
the factory) In space between
mainspring and inside diameter of
barrel, or between slip tail and inside
diameter of barrel through opening in
the date frame.
Rotate crown so that
mainspring and slip tail make 2 com -
plete
revolutions within the barrel to
distribute the oil properly. Release
mainspring power slowly as noted on
page 108.5 and
then remove screw ,
Date Frame and
Ratchet Wheel.

side; apply spreading type oil to bear-
ing
surface between barrel hub and

Reassembly of the Model108 Movement
Check assembly to be sure date changes as follows:
Turn crown so hands rotate clockwise until date advances one position. (This
should occur about midnight) . Rotate hands counterclockwise to 9 then
clockwise until date advances again.
Rotate hands
clockwise through 24 hours and date should advance one
position.
Loosen the set lever screw and remove the crown and stem. Position the Dial
and
Movement Assembly in the bezel; insert the Reflector Ring and replace the
crystal.
Insert the Crown and Stem Assembly through the bezel and into the movement
and retighten the set lever screw.
Reassemble
the Rotor Assembly by sliding it into the movement under the
rocker arm as shown in figure 2. (Notch in the rotor frame points towards the
Balance
Assembly.) Secure the rotor to the movement with two screws as
shown in figure 1. (It is sometimes easier to assemble the Rotor Assembly to
the movement first when Movement and Dial Assembly is to be assembled
through the back of the case and secured with a retaining ring.)
Position the caseback so the crown is to the left when the words are upright.
Recheck watch for proper function of the date setting mechanism .
