The Patek Philippe reference 5740 is the ultimate expression of the Nautilus collection, combining the iconic Gérald Genta-inspired sports-luxury design with one of the manufacture's most celebrated complications. Introduced in 2018, the 5740 was the first Nautilus to feature a perpetual calendar, powered by the ultra-thin automatic Calibre 240 Q with micro-rotor construction. Despite incorporating one of watchmaking's most sophisticated complications, the movement allows the case to remain remarkably slim, while the dial elegantly displays the day, date, month, moon phase, leap year and 24-hour indication in a beautifully balanced layout.

Produced in white gold at launch and later in rose gold, the reference 5740 represents the pinnacle of Patek Philippe's contemporary sports watch collection. Combining the practicality of a luxury sports watch with the prestige of a Grand Complication, it has become one of the most desirable modern Nautilus references, admired for its exceptional mechanical sophistication, elegant proportions and seamless integration of timeless design with haute horlogerie.
