This men's Citizen Eco-Drive® Perpetual Chrono A-T watch is constructed in stainless steel and features a black dial, a non-reflective crystal, luminescent hands, chronograph and daily alarm in a 42.0mm case. Citizen Eco-Drive® technology harnesses the power of any light source so it never needs a battery. The perpetual atomic-time feature means the watch automatically adjusts for odd and even months and leap years through the year 2100. The radio-controlled accuracy receives signals both automatically and on-demand from the USA, Europe and Japan. This watch is water-resistant up to 200 metres and secures with a polished link stainless steel bracelet with hidden push-button fold-over clasp. 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.
