The ETA 210.001 H1 (ESA 210.001 H1) Swiss quartz watch movement is a ladies’ 9 ligne, ultra-thin design measuring 20.40 mm in diameter with a thickness of just 0.98 mm. It features gold-colored plates, contains eight jewels, and operates using a 346 battery. The movement uses hand sizes of 100/50 (hour/minute) and is configured with height H1, identified by an hour wheel height of 0.71 mm, which should be matched when replacing an existing movement.
