Patek Philippe Grand Complications 5236P-001 In-Line Perpetual Calendar

The Patek Philippe 5236P‑001 introduces a groundbreaking approach to perpetual calendar design with its patented in-line display. Housed in a 41.3 mm platinum case, the watch features a vertical satin-finished blue dial with a black-gradient rim. At 12 o’clock, a single elongated aperture displays the day, date, and month in a panoramic view, enhancing legibility and elegance. Additional indicators include leap year and day/night apertures, with small seconds and moon phases positioned at 6 o’clock. The case is further distinguished by a brilliant-cut diamond set at 6 o’clock, and it is complemented by a shiny navy blue alligator leather strap with a platinum fold-over clasp.

Powering this timepiece is the self-winding Caliber 31-260 PS QL movement, a new development by Patek Philippe. This 34 mm movement comprises 503 components and operates at 4 Hz, offering a power reserve between 38 and 48 hours. It features a platinum off-centre mini-rotor, Gyromax balance, and Spiromax balance spring. The movement incorporates several innovations, including overlapping date discs and a security system to prevent double-jumps of the date, all under the Patek Philippe Seal. This watch represents a significant advancement in both design and mechanical engineering.
