Ulysse Nardin Marine Acqua Perpetual Calendar

The Ulysse Nardin Marine Acqua Perpetual Ref. 333/55 is a sophisticated nautical timepiece that combines professional sports-watch character with one of haute horlogerie’s most practical complications. Crafted in stainless steel, the watch features a robust rotating bezel, integrated steel bracelet, and a black textured dial with luminous hour markers for strong legibility.

Its automatic UN-33 calibre powers a perpetual calendar display with big date, day, month, year, and small seconds indications, offering exceptional mechanical refinement within a bold marine-inspired design. Distinguished, technical, and highly collectible, this timepiece reflects Ulysse Nardin’s deep connection to precision chronometry and maritime watchmaking.
