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.
In a first for a watchmaker, Eco-Drive products obtained Eco Mark certification, a label managed by the Japan Environment Association (JEA),
in recognition of their contribution to environmental sustainability in 1996. Eco-Drive went on to be awarded a
Gold Prize at the JEA's Eco Mark Awards 2014, a first in the watch business.
