caption_attribution_description: Deutsch: Modell Citizen CB0021-06E, H144
context_page_description: Eco-Drive is a model range of watches manufactured and marketed worldwide by Citizen Watch Co., Ltd., powered primarily by light. As of 2007, the company estimated the drive system had eliminated the disposal of ten million batteries in North America.
  Citizen introduced the Eco-Drive line to Asia, Latin America, and Europe in 1995 and to the United States in April, 1996.
  The Eco-Drive concept introduced several technical refinements over previous solar powered watches, including light-capturing cells that could be made virtually invisible behind the dial instead of highly conspicuous, enhancing the appearance of the watch.
