Patek Philippe Nautilus 5726

The Patek Philippe Nautilus 5726A-001 combines the Nautilus case design with an Annual Calendar complication that requires only one manual correction per year. The octagonal steel case measures 40.5 mm and features a sapphire crystal, with water resistance to 30 meters. The charcoal gray dial has a black-gradient rim and displays day, date, and month apertures alongside a 24-hour indication and moon phases. It is powered by the automatic Patek Philippe calibre 26-330 S QA LU 24H, offering a 45-hour power reserve.
