The Citizen Eco-Drive is the simplest, and yet the most technically advanced power generating and storage system in the Watch Manufacturing Industry. Powered by a solar conversion panel and energy cell, the Citizen Eco-Drive can use light from any source to generate electrical power. Thus the Citizen Eco-Drive's power supply is both limitless and free, and will last for a lifetime of use.

The mechanics behind the Eco-Drive are truly remarkable. A microns thin disc of amorphous Silicon under the dial converts light energy into electrical energy through a photovoltaic process. The electrical energy is then stored in a special energy storage cell. The high quality of this cell precludes it from being affected from the regular charge/discharge cycle as with an ordinary battery. As an added benefit to the environment, the energy cell contains none of the chemicals used in ordinary watch batteries.

Fueled by light, the Citizen Eco-Drive watches are unstoppable--just like the people who wear them.
