Patek Philippe Annual Calendar Chronograph 5960/1A-010

Patek Philippe 5960/1A-010 is a rare fusion of technical sophistication and sporty elegance, housed in a stainless steel case that marks a departure from the brand’s traditional use of precious metals for complicated watches. Its 40.5 mm case frames a striking black opaline dial, where three apertures display the day, date, and month in a clean annual calendar layout. At 6 o’clock, a monocounter chronograph subdial integrates 12-hour and 60-minute registers, accented by a red chronograph seconds hand that adds a dynamic touch. The dial also features a power reserve indicator and a subtle day/night display, underscoring its practical complexity. Powered by the automatic Caliber CH 28-520 IRM QA 24H, the watch offers flyback functionality and a vertical clutch system for smooth chronograph operation. Paired with an integrated stainless steel bracelet.
