Solar Eco-Drive Watch
Citizen’s Eco-Drive watch uses sunlight and any artificial light, absorbed through the crystal and dial. A solar cell beneath the dial converts any form of light into electrical energy to power the watch for a lifetime of use. The watch automatically sets the correct time using its Radio-Controlled feature but you can force a radio synchronization on demand or let the watch do the synchronization automatically.
