Eco-Drive Photon

This year marks the 50th anniversary of CITIZEN introducing the world’s first analogue light-powered watch (now known as Eco-Drive). Light-powered Eco-Drive technology, which drives watches using light that shines equally across the world, embodies CITIZEN’s corporate philosophy of being “loved by citizens, working for citizens.”

In the early 1970s, the world was in the midst of an energy crisis, and the engineers at CITIZEN looked to sunlight as an innovative, non-polluting energy source, with the aspiration of creating an environmentally friendly watch that eliminates the need for regular battery changes. In 1976, CITIZEN launched the world’s first analogue light-powered watch. Since then, for half a century, CITIZEN has evolved the functionality and design of Eco-Drive technology, which converts even the smallest amounts of light into energy. Today, Eco-Drive watches are worn in approximately 140 countries and regions worldwide.

Through Eco-Drive PHOTON, CITIZEN conveys the message that, just as Eco-Drive converts any light into energy to keep time moving forward, the unique brilliance of each wearer has the power to illuminate the future and society, driving progress.
