980-153 ETA Swiss Watch Movement

The ETA 980.153 H1 is a Swiss quartz ladies’ oval movement with three hands (hour, minute, small seconds). It measures 13.00 × 15.15 mm (5 1/2 × 6 3/4 ligne), has a total height of 2.20 mm, gold-colored plates, 7 jewels, and uses a 317 battery. Hand sizes are 120/70/20, and the H1 hour wheel height is 0.98 mm. For replacement, matching the hour wheel height is critical; the center-to-center distance from the hour wheel to the small seconds pinion is 4.25 mm, which ensures correct dial layout and hand alignment.
