This tiny movement was found in almost all, at least in all small, mechanical ladies’ watches without seconds indication. As most of the Timex movements, it used no jewels and was riveted on the front plate. On the dial side, there were the usual screws to dissect and service the movement.
Over the years, the movement was modified. On this old version from 1963, the movement plate had a justage inscription.
