CITIZEN ECO-DRIVE. Never change a battery again! The electrical energy produced by the solar cell is stored in the rechargeable battery and serves as the watch's power source. A fully charged battery will power a standard Eco-Drive watch for up to 6 months, and a watch with the Power Save function for up to 10 years*. Sunlight isn't the only power source for Eco-Drive watches. Even dim visible light such as light from a fluorescent lamp can be used to generate power. MyWatchShop sells only the most stylish Citizen Eco-Drive watches in stainless steel, titanium, gold tone and two-tone styles. Buy an Eco Drive watch and you’ll not only look great, you’ll be doing good for the environment.
