Introduced in 2018, the Patek Philippe Nautilus ref. 5740/1G-001 is the first Nautilus to feature a perpetual calendar. Its ultra-thin self-winding calibre 240 Q, with a micro-rotor, keeps the 40mm white gold case remarkably slim. The blue gradient dial, with its signature horizontal embossing, displays day, date, month, leap year and moon phase. This 2022 example comes as a full set in excellent condition. Rare and elegant, the 5740/1G is one of the most accomplished complications in the modern Nautilus family.
