Patek Philippe Nautilus Perpetual Calendar

About this reference

The Patek Philippe Nautilus Perpetual Calendar 5740/1G-001 was introduced in 2018 as the first grand complication in the Nautilus collection and remains in current production. It features a 40mm case and integrated bracelet crafted from 18k white gold, housing the ultra-thin self-winding caliber 240 Q. This movement allows the case to maintain a profile of 8.42mm, making it the thinnest perpetual calendar in the brand's catalog. The dial is finished in blue sunburst with horizontal embossing and features three sub-dials indicating the day, date, month, leap year, 24-hour cycle, and moon phases. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often fluctuating between $210,000 and $260,000 depending on condition and provenance. A notable production detail is the inclusion of the fold-over clasp with four independent catches for improved security compared to earlier Nautilus iterations.
