CITIZEN ECO-DRIVE

In 1976, CITIZEN 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 their exceptional technological achievements, but one that reflect their concern for the natural environment. Most importantly, the name and the logo mark shows their continued dedication to be a brand for people all over the world.
