The ETA 803.161 quartz watch movement is a ladies’ round, four-hand movement featuring 24-hour, hour, minute, and seconds hands, with a date window positioned at 3 o’clock. The 24-hour hand can be used either as a standard 24-hour indicator or to track a second time zone. This 8¾ ligne movement measures 19.40 mm in diameter, has a height of 3.65 mm, and is configured with movement height H4. It features black-colored plates, contains no jewels, and operates on a 377 battery. Hand sizes are 160/120/70/20 (24-hour/hour/minute/seconds), and the H4 height is identified by an hour wheel height of 2.26 mm, which should be matched when replacing an existing movement.
