From the Perpetual Chrono A-T Collection. The best-selling Perpetual Chrono A-T watch from CITIZEN® has been updated with new features without losing its original appeal that made it stand out from the crowd. Some of those features include our proprietary Eco-Drive technology, so the watch will never need a battery, as well as atomic timekeeping in 24 time zones, a chronograph, perpetual calendar, and power reserve indicator. The two-tone stainless steel bracelet is offset by the black dial with gold-tone accents for a sleek, sophisticated look that won’t be out of place in the boardroom, at the beach, or anywhere in-between.
