Patek Philippe Perpetual Calendar 5040J – SEALED

Patek Philippe 5040J is a refined expression of classical watchmaking, distinguished by its rare tonneau-shaped case and perpetual calendar complication. Crafted in 18k yellow gold, the 5040J features a graceful 32.25 x 35.6mm case that departs from Patek’s more traditional round profiles, offering a subtle nod to Art Deco elegance. The silvered dial is adorned with applied Breguet numerals and leaf-shaped hands, framing three recessed sub-dials that display day and 24-hour indication (9 o’clock), month and leap year (3 o’clock), and date with moon phase (6 o’clock). At its heart is the ultra-thin automatic caliber 240 Q, featuring a 22k gold micro-rotor, Gyromax balance, and 27 jewels, ensuring precise timekeeping and seamless calendar transitions—including leap years—without manual correction for decades.
The watch is protected by a scratch-resistant sapphire crystal, paired with a black crocodile leather strap. Water-resistant to 30 meters, it balances everyday wearability with high complication.
