In 1976, we invented the world’ s first light-powered analogue quartz watch that runs using only light as a power source.

Watches Powered by Light Eco-Drive is designed to convert both natural and artificial light into energy to power watches. Watches with Eco-Drive do not require any battery replacement, charging or winding to maintain constant operation.

One of the factors that distinguishes CITIZEN’ s Eco-Drive from other methods of keeping watches running at all times is its “power life.” Eco-Drive watches continue running for more than six months on a full charge, even in total darkness. Thanks to our power saving function, CITIZEN makes it possible to develop watches that can operate for up to seven years without light.
