How it works
In 1976, we invented the world's first light-powered analog quartz watch that runs using only light as a power source. This technology, now known as "ECO-DRIVE," can generate power from any light source -- artificial, natural, and even dim light -- to keep watches running without ever replacing batteries.
CITIZEN’s proprietary light-powered technology, was called “Eco-Drive“. A name that, not only represent our exceptional technological achievements, but one that reflect our concern for the natural environment. Most importantly, the name and the logo mark shows our continued dedication to be a brand for people all over the world.
