ETA SA 450-111

The ETA caliber 450.111 is a quartz movement manufactured by ETA SA in Switzerland. It displays the date at 3:00 and contains 395 jewels, which is unusually high for a quartz caliber. A related caliber, the 450.121, adds day display alongside the date. The movement's gear train is exposed without a cover plate, which should be noted when servicing.
