Citizen’s first light-powered analog watch, the Crystron, was released in 1976, and in the four decades since that initial offering Citizen has painstakingly refined the technology, creating watches that are not only more efficient, but also far more refined.For 2016, Citizen is celebrating the 40th anniversary of Eco-Drive, the brand’s pioneering technology of powering watches through light.
