Eco-Drive How It Works

CITIZEN created the world's first light-powered analogue quartz watch in 1976. We named the technology Eco-Drive in acknowledgement of its eco-friendly origins. It converts any kind of light into energy to power a watch and stores 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. As a light-power pioneer, we continue exploring new possibilities. https://www.citizenwatch-global.com/technologies/eco-drive/
