The first Grand Complication in the Nautilus collection (2018), this white gold perpetual calendar features an original blend of sportiness and technical sophistication. Thanks to the presence of the famous ultra-thin self-winding Caliber 240 Q, the case retains the exceptional slimness that makes it the thinnest Patek Philippe perpetual calendar. Maker: Patek Philippe. Reference: 5740/1G-001. Available through ELITA's private desk — verification review, discreet handling and storage. Price on request.
