255-421 ETA Watch Movement

The ETA 255.421 quartz watch movement is a high-quality, slim-profile caliber featuring a three-hand display (hour, minute, and seconds) with both day and date complications. It measures 10 ½ lignes in diameter with a height of 2.45 mm. This movement uses hand sizes 120/70/20 and provides a robust, professional-grade Swiss quartz solution for mid-sized watch designs requiring a full calendar readout within a refined and low-profile architecture.
