The FS27 Miyota Quartz Watch Movement is a dual-time chronograph featuring four central hands—local 12-hour, home 12-hour, minute, and chronograph seconds—along with three sub-indicators and a suspended date window at 4:30. This 0-jewel, 10½-ligne round movement measures 23.70 mm by 22.00 mm, with a movement thickness of 5.10 mm and an overall height of 7.28 mm. Its sub-dial at 2 o’clock displays a 24-hour local-time indicator, the 6 o’clock sub-dial shows small seconds, and the 9 o’clock sub-dial records up to 60 minutes. Designed for straight-walled cases, the pushers are parallel rather than slanted. Hole sizes are 120/70/17/26 for the hour, minute, seconds, and indicator hands. The FS27 uses a 377 battery and is compatible with stem part number 065-549 (tap 0.90 mm / tap 10).
