Citizen Eco-Drive Watches

In 1976, Citizen invented the world’s first light-powered analog quartz watch that runs using only light as a power source. This technology, now known as “Eco-Drive,” can generate power from any light source, artificial, natural and even dim light to keep watches running without ever replacing batteries.

Darkness Is not a Concern. 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
