Patek Philippe 5960P Annual Calendar Chronograph Platinum Gray Dial

Introduced in 2006, the Patek Philippe 5960P‑001 represents a landmark in modern haute horlogerie, being the first automatic chronograph entirely developed in‑house by the manufacture. Housed in a substantial yet elegantly restrained 40.5 mm platinum case, this reference blends a flyback chronograph with an annual calendar, a power reserve indicator, and a day/night display into a uniquely balanced and legible dial layout. The sunburst grey dial, punctuated by applied white‑gold markers and framed calendar apertures, conveys both technical sophistication and refined aesthetics. Inside, the CH 28‑520 IRM QA 24H calibre showcases Patek’s vertical clutch, column‑wheel chronograph architecture, and 21k gold rotor, all finished to Geneva Seal standards. Its exhibition caseback reveals the movement’s meticulous decoration—Côtes de Genève, polished bevels, and circular graining—underscoring the brand’s commitment to craftsmanship. As the debut model of the 5960 series, this platinum variant remains highly coveted by collectors for its historical importance, technical innovation, and enduring design. The combination of complication, in‑house movement, and noble metal construction cements its status as a modern Patek classic. Like New with Patek Philippe box and papers dated 2007.
