Citizen Eco-Drive. Powered By Light

Draws power from a single source; Light....any light. Not only bright sunshine, but cloudy days, or even artificial light. Eco-Drive converts light into electrical energy which is stored in a rechargeable power cell, driving the motor, gears, and hands. On a single full charge, the Eco-Drive watch can run for over 6 months - even when stored in the dark, resulting in never having to change your battery.
