The Tissot 3112 watch movement, produced between 1963 and 1966, features a ball-bearing rotor with a peripheral gear positioned off-center. It is likely equipped with 5 ruby balls, and boasts a relatively large balance. The movement's ratchet is located on the dial side, and it incorporates a crown mechanism with a rocker bar. The Tissot 3112 movement offers automatic winding, a sweep second hand, and a date function that can be adjusted by changing the time between 22:30 and 24:00.
