Patek Philippe 5960P Annual Calendar Chronograph Platinum Blue Dial

The Patek Philippe 5960P‑015 Annual Calendar Chronograph in 950 platinum with a striking blue sunburst dial was introduced circa 2010 as the platinum variant of the groundbreaking 5960 series, the first regular-production in-house automatic annual calendar chronograph from Patek. Its 40.5 mm case, measuring approximately 13.55 mm thick, houses the calibre CH 28‑520 IRM QA 24H, a column‑wheel flyback chronograph with vertical clutch, annual calendar, power‑reserve indicator, and day/night display, all hallmarks of Patek’s technical mastery. The blue dial, with its large date at 12 o’clock, day and month apertures, and a combined 60‑minute/12‑hour monocounter at 6 o’clock, offers superb legibility and elegant balance. The platinum case features a sapphire display back and a discreet diamond at 6 o’clock, underscoring its luxurious execution. Paired with a blue alligator strap and platinum folding clasp, this reference blends robust functionality with refined aesthetics. Discontinued in 2014, the 5960P‑015 remains highly sought after by collectors for its pioneering movement and limited production window, representing both horological significance and enduring elegance. Excellent Condition with Patek Philippe box, setting pin, and papers dated 2010.
