FS23 Citizen Miyota Watch Movement

The Miyota FS23 is a 0-jewel quartz chronograph movement featuring central hour, minute, and seconds hands, three sub-dials, and a suspended date window at 4:30. Sized at 10½ ligne (23.70 mm × 22.00 mm), it has a movement thickness of 5.10 mm and an overall height of 7.30 mm. As the high-hand execution of the FS20, it retains the same functional layout: a 24-hour indicator at 2 o’clock, a 60-second indicator at 6 o’clock, and a minute counter at 10 o’clock. Designed with slanted pushers for round cases, it uses hole sizes 120/70/17/26 (hour/minute/seconds/sub-dials), operates on a 377 battery, and uses stem part number 065-549 (tap 0.90 mm / tap 10).
