The ETA E03-001 H1 (E03.001) quartz watch movement is a ladies’ oval-shaped, two-hand movement displaying hour and minute. It measures 5½ × 6¾ ligne (13.00 mm × 15.15 mm) with a slim height of 1.40 mm and features the H1 height configuration. The movement has gold-colored plates, contains six jewels, and operates on a 335 battery. Hand sizes are 100/55 (hour/minute), and the H1 height is identified by an hour wheel height of 0.71 mm, which should be matched when replacing an existing movement.
