Citizen Better Starts Now In 1976, Citizen invented the worlds first light-powered anolog quartz watch that runs using only light as a power source. Eco-Drive technology converts light into electrical energy which is stored in a rechargeable lithium ion power cell to keep the watch running forever. The ultimate convenience to the wearer is never having to change your watch battery again. Eco-Drive watches are designed so that any light source, no matter how dim, will generate the energy needed to power the watch. Even in total darkness, Eco-Drive watches keep running for more than six months on a full charge.
