It starts with a simple, yet revolutionary concept: A watch that never needs a battery.
How It WorksEco-Drive
The watch that never stops, wherever you are.
Inventing a technology to ensure watch that never stops anywhere in the world was one of the challenges for CITIZEN. 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, we set new challenges for ourselves to bring forth the full potential of power generation using light. CITIZEN’s Eco-Drive technology has won acclaim in Japan and other countries for its contribution to environmental protection. In 1996, an Eco-Drive watch was nominated as the first watch to qualify for the Eco Mark, a label managed by the Japan Environment Association (JEA). In 2014, CITIZEN became the first watchmaker to earn a Gold Prize in the JEA’s Eco Mark Awards.
