Building a purposeful, powerful, and sustainable future. From the birth of its Eco-Drive light technology to today, Citizen looks for ways to support and celebrate the planet.

Eco-Drive is designed so that any light source, no matter how dim, will generate the energy needed to power the watch. Light itself is the only energy source required to tell the time with an Eco-Drive watch.

Our Citizen Mens Eco-Drive watches are powered by ANY light, not just solar powered, for the ultimate ease of ownership. 5-year limited warranty accompanies every purchase on the official Citizen website. | CITIZEN

Eco-Drive converts any kind of light into energy to power a watch, storing 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. It’s designed to charge from ordinary everyday light sources like indoor fluorescent lighting and desk lights.

Eco-Drive is a proprietary CITIZEN technology that converts any kind of light, from bright sunshine to dim indoor lighting, into the energy necessary to power a watch. It runs for over six months off a single full charge. CITIZEN released the world's first light-powered analogue watch in 1976.
