The Citizen caliber 7871 (7871A) is a solar-powered quartz movement manufactured in Japan and introduced in 1990. It powers various Citizen Eco Drive watches, using a capacitor as its power source rather than a conventional battery. The movement was discontinued but remains notable as one of Citizen's earlier solar quartz calibers.
