Citizen One AR5050-51L
Timeless design, breakthrough technology. This hand-assembled masterpiece is what happens when elevated engineering and next-level innovation come together. The Eco-Drive One is the thinnest, analog, light-powered watch in the world. This new addition to the collection features a blue dial with Duratect Alpha-coated steel for lightweight durability—and five times the hardness of stainless steel. Powered by the Eco-Drive Caliber 8826 and sporting an ultra-thin 39mm case just 2.98mm thick, this incredible timepiece features a sapphire crystal with “Clarity” coating, 3 bar of water resistance, and 12 months of running time on a full charge with an accuracy of +/- 15 seconds per month. This collection has since come to define the marriage of advanced, light-powered movement technology and ultra-thin watchmaking in the 21st century. When paired to a 0.15mm synthetic sapphire dial and crystal, with a brand-new, rechargeable 3.7V power cell from Maxell, the result is a breakthrough watch the world has never before seen.
