CITIZEN's Eco-Drive technology has won acclaim in Japan and other countries for its contribution to environmental protection. In 1996, an Eco-Drive watch was nominated as the first watch to qualify for the Eco Mark, a label managed by the Japan Environment Association (JEA). In 2014, CITIZEN became the first watchmaker to earn a Gold Prize in the JEA's Eco Mark Awards.

The oil crisis in 1973 raised global awareness and interest around alternative sources of clean energy. CITIZEN responded to the challenge by starting to develop watches driven by a completely new energy source: light. And in 1976, they created the world’s first light-powered watch.
The technology was named Eco-Drive. This technology can generate power from any light source, artificial, natural, and even dim light to keep watches running without ever replacing batteries. As a pioneer of the field, Citizen set new challenges for themselves to bring forth the full potential of power generation using light.
