The Citizen Men's Eco-Drive® watch pairs modern technology with bold features. The stainless steel case and bracelet with hidden, push-button fold-over clasp are plated in an elegant Grey tone which complements the handsome black dial. Grey-toned hands and hour indexes, a dual-time function, and a self-adjusting perpetual calendar are subtle yet eye-catching. The anti-reflective mineral crystal is scratch resistant. Powered by Japanese quartz movement and fueled by natural and artificial light, the watch is ecologically friendly and functions without a battery. Water resistant to 100 meters. This watch includes a five-year limited manufacturer warranty, with an additional one-year warranty upon registering your watch with Citizen. We are an authorized Citizen dealer.
