Its fascinating appeal originates from a surprisingly modern form with a gently rounded octagonal shape. The surface structure of the superbly finished landmark dial reflects the attractive texture of the strap. The complex construction of the case is underscored by the screw-down crown for extra protection on the wrist of active people. The Tropical strap, made of a high-tech composite, is soft, comfortable, resistant and hypoallergenic.
The Nautilus with perpetual calendar Ref. 5740/1, the first major complication in the Nautilus collection.
The 40mm white gold case with a Blue Soleil dial is water resistant up to 60 meters. Thanks to the presence of the famous ultra-thin 240 Q self-winding caliber it maintains an extraordinarily reduced thickness, becoming the flattest perpetual calendar in the Patek Philippe collections. The white gold bracelet is equipped with a new Nautilus folding claps which offers optimized security.
