Timex M78


The Timex M78 is a direct relative of the “standard” movement Timex M100. The most important difference is, that on the Timex M78, the dial is directly mounted onto the base plate. Unlike many other timex Movements, it is even serviceable, since the top plate is not riveted but mounted with screws.

The Timex M78 offeres a center second indication, which is not used every time.

As all simple timex movements, it uses no jewels and beats with slow 18000 A/h.
