Citizen Eco-Drive started with a simple, yet revolutionary 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.
