Citizen Eco-Drive Technology

It starts with a simple, yet revolutionary concept; a timepiece that never needs a battery change.

Citizen Eco-Drive technology harnesses the power of light - from any natural or artificial light source - and converts it into energy which is stored in an Eco-Drive energy cell.

It charges continuously an any kind of light to run forever.

How Citizen Eco-Drive Works

Sunlight and artificial light are absorbed through the crystal and dial

A solar cell beneath the dial converts any form of light into electrical energy to power the watch

A lithium-ion rechargeable battery stores enough energy to power the watch from 80 days to 5 years
