The ETA 902.101 H1 quartz watch movement is a ladies’ oval-shaped, three-hand movement displaying hour, minute, and seconds. It measures 6¾ × 8 ligne (15.30 mm × 17.80 mm) with a height of 2.35 mm and is configured with movement height H1. The movement features gold-colored plates, contains four jewels, and operates on a 364 battery. Hand sizes are 120/70/20 (hour/minute/seconds), and the H1 height is identified by an hour wheel height of 0.94 mm, which should be matched when replacing an existing movement.
