Story: 

The oil crisis in 1973 raised global awareness and interest around alternative sources of clean energy. CITIZEN responded to the challenge by starting to develop watches driven by a completely new energy source: light. And in 1976, we created the world’s first light-powered watch. The technology was named Eco-Drive.

Eco-Drive converts any kind of light into energy to power a watch, storing the surplus on a power cell. On a full charge, an Eco-Drive watch runs for months even in darkness with no need for regular battery replacement. It’s designed to charge from ordinary everyday light sources like indoor fluorescent lighting and desk lights. You can go about your everyday life confident that your watch will never stop.
