Service Guide CAL. Y482F - Seiko Watch Movement
Service guide for the Seiko caliber Y482F quartz watch movement, providing complete technical specifications and repair information for authorized service centers and skilled technicians. Movement dimensions are 18.4mm outside diameter, 17.8mm casing diameter, and 2.8mm height. The Y482F uses a two-hand time indication system driven by a step motor with load-compensated driving pulses, ensuring accurate timekeeping across varying conditions. An electronic reset switch enables accuracy checks, while a 10-second measuring gate supports precision testing. The movement runs on a 1.55V battery—either SR621SW or 364 type—with typical life expectancy around 2 years under normal use and current consumption below 1.2µA. The guide covers winding stem replacement procedures and hand installation techniques, essential knowledge for completing movement service and restoration on this caliber.
