ECO DRIVE (THE LIGHT POWERED WATCH)

Owning a watch usually means putting in a new battery every few years. Not any more. The battery that goes into Eco-Drive is so efficient it never has to be replaced. One less change to worry about, one more reason why Citizen is at the forefront of watch making.

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.
