Citizen Eco Drive Dive Watches

The watch that never stops, wherever you are.

Citizen dive watches are some of the best in the world and inventing a technology to ensure a watch that never stops anywhere in the world was one of the challenges for CITIZEN. In 1976, they invented the world’s first light-powered analog quartz watch that runs using only light as a power source. This technology, now known as “Eco-Drive,” can generate power from any light source, artificial, natural and even dim light to keep watches running without ever replacing batteries. As a pioneer of the field, Citizen set new challenges for themselves to bring forth the full potential of power generation using light.

Eco-Drive Features

Watches Powered by Light

Eco-Drive is designed to convert both natural and artificial light into energy to power watches. Watches with Eco-Drive do not require any battery replacement, charging or winding to maintain constant operation.

Easy to charge even in Dim Light

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.

Darkness Is not a Concern

One of the factors that distinguishes CITIZEN’s Eco-Drive from other methods of keeping watches running at all times is its “power life.” Eco-Drive watches continue running for more than six months* on a full charge, even in total darkness. Thanks to our power saving function, CITIZEN makes it possible to develop watches that can operate for up to seven years without light
