Citizen didn't just adopt solar power — it invented it for watches. The 1976 Crystron Solar Cell was the world's first light-powered analog watch, and the technology behind it evolved into Eco-Drive, which fifty years later still powers the majority of Citizen's lineup and generates energy from artificial light as well as sunlight.
This BM8180-71W carries that technology in a conventional three-hand dress watch — steel case and bracelet, day display, and a 100-meter water resistance rating, with no battery to ever replace.
