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.

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.
