The idea of Eco-Drive starts with a simple, yet revolutionary concept: a watch that never needs a battery. Citizen Eco-Drive technology harnesses the power of light- from any natural or artificial light source ?and converts it into energy, which is stored in an Eco-Drove energy cell. It recharges continuously in any kind of light to run forever. Citizen 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. A special Eco-Drive energy storage cell is used. It is of such quality that the regular charge/discharge cycle affects it to such a small degree that it doesn't need to be replaced like an ordinary battery. With normal care and exposure to light, the owner can be assured of a lifetime of reliable and trouble free time-keeping. As an added benefit to the environment, the energy cell contains none of the caustic chemicals used in ordinary batteries Calibre 8700 Collection.
