Patek Philippe 5235/50R Regulator Annual Calendar 18K Rose Gold Gray Dial

The Patek Philippe 5235/50R-001 is a defining example of the brand’s technical prowess and creative daring, originally released in 2019. Crafted in luxurious 18K rose gold, the 5235/50R-001 stands out within Patek Philippe’s collection as a regulator: the hours, minutes, and seconds are each displayed on separate subdials, echoing 19th-century observatory clocks used for benchmark precision. The vertically satin-brushed two-tone gray and ebony black dial creates a sophisticated yet modern aesthetic, while the annual calendar complication—powered by the in-house automatic caliber 31-260 REG QA—demonstrates mechanical ingenuity, requiring manual correction only once per year. Collectors prize the off-center micro-rotor with 22K gold, a solution rarely seen and revered for its slimness and winding efficiency. This reference showcases Patek Philippe’s commitment to horological artistry and technical innovation, offering unique wrist presence and historic regulator heritage. Highly sought-after since its debut, the 5235/50R remains one of the most distinctive modern Patek dress complications. Like New with Patek Philippe box and papers dated 2021.
