Item InformationCitizen Eco-Drive watches use the simplest, yet most technically advanced power generating and storage system in the Watch Manufacturing Industry. A Solar conversion panel and energy cell are the power provider for these Quartz Watches. Eco-Drive's ability to use light from any source to generate electrical power means that the supply is limitless and free. The absence of any added complex power generating machinery that would require additional upkeep is another big advantage.
The Eco-Drive watch uses a microns thin disc of amorphous Silicon under the dial to convert light energy into electrical energy through the photovoltaic process. The electrical energy is then stored in a special energy storage cell . The charging is done in a more efficient manner than was ever before thought possible. Because of this newly developed technology, it is now practical to use a wide variety of attractive dials.
A special Eco-Drive energy storage cell is used to store the electricity from the converted light energy. The high quality of the cell precludes it from being affected from the regular charge/discharge cycle as with an ordinary battery. With normal care and exposure to light, the owner can be assured of a lifetime of reliable and trouble free power. As an added benefit to the environment, the energy cell contains none of the chemicals used in ordinary watch batteries.
The rechargeble cell featured in Eco Drive watches is a highly specialized unit that will last a lifetime of use. Many times, it is incorrectly referred to as a "capacitor".
It is highly unusual for these cells to fail. Most commonly, if an Eco Drive is stopping it is more indicative of a low charge. If it is running slow, it may indicate it is time to have the movement serviced. *Stainless Steel Two-Tone
