What is the ideal source of power for a watch?
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.
