Timex M101

Description

The Caliber M101 was made in the very last years of mechanical Timex movements, in 1984. As all other movements of the series 100, it bases on the caliber M100. The caliber 101 only adds a date indication.

It is a very simple and rugged pin lever movement. Theoretically it can be serviced, but normally, defective movements are swapped and easily replaced by working ones.
