251-491 ETA Watch Movement

The ETA 251.491 quartz watch movement is a sophisticated, slim-profile caliber featuring a two-hand main display (hour and minute) with a small seconds sub-dial positioned at the 6 o'clock mark. It measures 10 ½ lignes in diameter with a height of only 2.45 mm. This movement uses hand sizes 120/70 and provides a high-quality, precise Swiss quartz solution for elegant watch designs that require a classic sub-second layout within a compact and low-profile architecture.
