Service Manual TIMEX Model 52

13 1/2 lig. 30.5 mm 1.20 in. The Timex Model 52 is a 13 1/2 ligne electronic day-date movement. The Model 52 movement is similar to the Model 50 movement except that a calendar and a day mechanism has been added. The power to drive the movement is supplied by a miniature energy cell. Power from the energy cell drives the balance. The balance drives the time train which, in turn rotates the hands. The day can be changed either forward or backward by pulling the crown out to the set position and turning through 24 hours in either direction. The date can be changed only in the increasing direction by first pushing the crown into the run position and then turning the crown in a counterclockwise direction. The date will increase one number for each half turn of the crown. Do not attempt to turn the crown clockwise when in the run position. Basic servicing techniques are similar to those used for the Model 50 except that all hands must be removed prior to removing the dial.
