Citizen Eco Drive Chronograph - Model E870-s015278-HST-790467 – Vintage Watch Specialist

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.
