Nautilus Men’s - 5726/1A 40.5 mm, stainless steel, 324 S QA LU 24h automatic manufacture caliber with moon-phase display and annual calendar | Reference Number PP400034

With a new blue dial inspired by the color of the first model from 1976, Patek Philippe adds a fresh touch to the athletic aesthetics of the Nautilus. The quintessential horizontal embossing toward the edge is emphasized by the design’s subtle black gradient. The calendar indicators and moon phase, which include a 24-hour display, merge harmoniously into an ensemble featuring applied gold hour markers with a luminous coating. The case is water-resistant up to 120 meters and measures 40.5 x 11.3 millimeters, while inside it there is a 324 S QA LU 24H/30 automatic caliber.
