POWERED BY LIGHT Eco-Drive 40 Years

40 Years of Eco-Drive

In 1976, 40 years ago this year, CITIZEN created the world’s first analogue light-powered watch.

We called the technology Eco-Drive. With Eco-Drive, our watches generate energy even from dim light and run for months, even in the dark.

We went on to create a whole series of watches—watches with multi-functions; watches that are smaller, thinner, and more beautiful; watches that everyone can relate to, even love.

The challenge, however, goes on. Because we believe it is always possible to make something better.

As a light-power pioneer, we will continue to explore new possibilities for the future of the watch and to craft timepieces that inspire people everywhere.

Eco-Drive “How it Works”

Eco-Drive is a CITIZEN core technology. It generates energy even from dim light and stores the surplus on a power cell, eliminating the need to replace batteries.
