Eco-Drive is the series name of a line of mainly light powered watches manufactured by the Citizen Watch Co., Ltd. In 1995 Citizen introduced the Eco-Drive line to Asia, Latin America and Europe. In the United States the first Eco-Drive watches were sold in April 1996.
The Eco-Drive concept introduced several major technical refinements over previous solar powered watches. The combination of these refinements for the first time gave watch designers the opportunity to design light powered watches without the need to incorporate conspicuous solar cells on the watch dial.
