[Citizen] CITIZEN Watch ECO-DRIVE Perpetual Calendar Chronograph BL5551-14H Men's Black

Citizen’s unique light-powered technology “Eco-Drive” is installed, generating power by receiving light with the solar cell built into the watch, which drives the watch. Also, excess electrical energy is stored in a secondary battery, eliminating the need for regular battery replacements, and the secondary battery used does not contain harmful metals. Furthermore, harmful substances are not used in the manufacturing process, and as such, it receives extremely high praise from an ecological standpoint, and is the first watch to be certified as an “Eco Mark Product.”
