Seiko Calibre 2E20B Two-Hand Quartz Watch Movement
The Seiko 2E20B is a compact battery-powered quartz movement designed to display the hours and minutes. Its two-hand mechanism advances at 20-second intervals and provides reliable operation for compatible watches.
The movement features a train-wheel setting device and electronic circuit-reset switch. Powered by an SR521SW silver-oxide battery, it offers an estimated battery life of approximately three years under normal operating conditions.
Movement compatibility depends on the watch case, dial configuration, hand fittings, stem position, and movement holder. Please compare all specifications with the existing movement before ordering. Professional installation is recommended.
