Please note that if you wear your new Citizen Eco-Drive timepiece on a regular basis, recharging will be virtually automatic as regular exposure to light will keep your power reserve unending. Recharge times will vary based on your timepiece and the type of light utilized; direct sunlight is the fastest, most efficient light source for recharging. Once fully charged, your Eco-Drive will continue running for approximately six (6) months.
