5740/1G – Nautilus

The first Grand Complication in the Nautilus collection, the Reference 5740/1 Nautilus perpetual calendar, offers a distinctive blend of sports appeal and technical sophistication. Thanks to the famous ultra-thin self-winding caliber 240 Q movement, the case (water resistant to 60 m) is remarkably svelte, making this watch Patek Philippe’s thinnest perpetual calendar. The bracelet is equipped with a new fold-over clasp providing optimized security.
