For 2016, Citizen is celebrating the 40th anniversary of Eco-Drive, the brand’s pioneering technology of powering watches through light. 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.
The Eco-Drive One
The culmination of that effort is the Eco-Drive One, Citizen’s big reveal for Baselworld 2016. At a thickness just shy of 3mm, The Eco-Drive One is the thinnest solar-powered timepiece ever produced. Driving the watch is Citizen’s new caliber 8826—a movement made up of 85 components and just 1mm thick. Despite being so thin, the Eco-Drive One is capable of running a whopping 10 months on a full charge.
