Two Advanced Research Titans From Patek Philippe

Patek Philippe established its Advanced Research department in 2005 to focus on innovative movement components, enhancing the functionality of its timepieces. This initiative reflects the brand's commitment to blending tradition with modern advancements. The Advanced Research collection showcases two notable models: the 5650G Aquanaut Travel Time and the 5550P Perpetual Calendar. The 5650G is designed for sporty functionality, featuring a water-resistant case and a tropical rubber strap. It incorporates the Advanced Research Calibre 324 SC FUS, which includes the Spiromax balance spring made from a proprietary silicon derivative. This innovation significantly improves accuracy, rivaling that of Patek Philippe's Tourbillon escapements. In contrast, the 5550P is an automatic perpetual calendar housed in a 37.2mm platinum case. It showcases a balanced dial with three subdials for calendar functions. The watch is powered by Calibre 240 Q Si, which features a Silinvar balance wheel that minimizes friction and eliminates the need for lubrication. A loupe on the sapphire crystal caseback allows wearers to admire this advanced escapement. Both models exemplify Patek Philippe's dedication to horological excellence, merging cutting-edge technology with the brand's rich heritage. The limited production of the 5550P, with only 300 pieces made, further emphasizes the exclusivity and desirability of these timepieces among collectors.
