If you are looking at the limited-production Ulysse Nardin Marine Chronometer Manufacture watch (888 pieces only). Its 43mm round case is made of 18K rose gold and features an exquisite, round fluted bezel, giving the watch an eye-catching look. Its strap is made from black alligator leather and sports a firm deployment clasp. The case is accented by a beautiful white enamel dial that uses black luminescent hands and a small seconds subdial at 6 o'clock to show time in hours, minutes and seconds. A power reserve indicator appears below 12 o'clock while the watch's date display appears infused together with the small seconds subdial at 6 o'clock. Ulysse Nardin's rigorous manufacturing standards and strict testing ensures the watch can be safely used up to a water depth of 100m, making it suitable for snorkeling and swimming.
