Timex M64

Description

This is the earliest “Quartz” movement from Timex. Other than in later quartz movements, it is just an electromechanical movement, where the balance is controlled by a quartz-driven circuit. The quartz beats with 49152Hz, which is the result of the balance beating 6 amplitudes per second, and this multiplied with 2^13. This movement shall run within 1 second deviation per day. It can be corrected by a conventional hairspring regulator and by a variable resistor.

As many other Timex movements, it also has got a day-date feature with jumping day and semi-fast correction.
