Patek Philippe 5960P Annual Calendar Chronograph Platinum Gray Dial

This Patek Philippe Annual Calendar Chronograph reference 5960P-001 marked a turning point in the firm's modern complicated watches. It was the first Patek Philippe to unite an annual calendar with a self-winding in-house chronograph, a combination that gave the reference its place in the line from the start. Its automatic caliber CH 28-520 IRM QA 24H brought together a column wheel, a vertical clutch, and an annual calendar in one movement, which is much of why the 5960 still holds its own in the brand's recent history. For a collector drawn to watches that changed Patek's technical direction rather than simply extending it, this is the reference that set the pattern. In platinum, the case measures 40.5mm across and 13.5mm thick, giving the watch the broad, confident stance that defined complicated Patek Philippe design in this period. The gray dial keeps that modern character intact. More than a successful reference, the 5960P is where Patek Philippe's contemporary chronograph era properly begins. This Annual Calendar was just fully serviced By Patek Philippe in Q3/2026.
