POWERED BY LIGHT. ANY LIGHT. A WATCH THAT NEVER NEEDS A BATTERY.
It starts with a simple, yet revoluitionary concept: a watch that never needs a battery. 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 a permanently rechargeable lithium-ion cell. It recharges continuously in any kind of light to run forever.
