Patek Philippe Nautilus 5740

The Patek Philippe Nautilus 5740/1G-001 is the first Grand Complication introduced in the Nautilus collection, combining a perpetual calendar with the collection's sporting case design. The case is made of white gold with an octagonal shape and measures 40 mm, paired with a sapphire crystal and a blue dial. It is powered by the self-winding Caliber 240 Q, an ultra-thin movement that allows the watch to remain the thinnest perpetual calendar in Patek Philippe's range, offering 48 hours of power reserve and water resistance to 30 meters. Functions include the perpetual calendar with date, weekday, and month displays, along with a moon phase indication.
