Timex 25 - TIMEX Model 25 Movement Overview; Movement Construction Details

the TIMEX Model 25 Movement
The Timex Model 25 is on 11
1
/4 '" x 9 1;4 "' calendar movement utilizing the
basic construction of the Model 24 . Like the Model 24 it features a "V-Conic"
Bearing system and rugged two plate design. The entire Calendar mechanism
is efficiently housed between the dial plate and dial.
Whereas most watches utilize bridges, TIMEX has constructed the Model 25
movement with full plates to toke advantage of the accuracy inherent in this
type of design. This accuracy insures complete interchangeability for the escape-
ment and gear train without the need for selective fitting and adjustments which
complicate the repair of most watches .
To clean the TIMEX Model 25 it is necessary to remove only the sweep second
hand, dial, dote ring, dote wheel assembly, ratchet wheel, and balance . The
illustrations on pages 25.3 through 25.5 show proper procedures . TIMEX has
found through long and careful research that the best method of cleaning is
with only the above mentioned ports removed. The cleaning fluid, while remov-
ing any contamination from the movement will also remove oil from the gear
•rain, pivots and holes.
If
further dismantling is required, removal of the movement plate will expose the
gear train and associated ports . Re-assembly should start with the dial plate,
exercising normal core to insure proper positioning of pivots in their respective
holes.
The exploded view of the movement on page 25 .2 will guide re-assembly.
