Patek Philippe 5960/1A-001

Patek Philippe

This stainless steel model is the first Patek Philippe watch to feature an annual calendar chronograph, introduced in 2014. The self-winding Cal. CH28-520 movement, manufactured in-house, minimizes the wear on the gears caused by chronograph operations and can be run continuously like a small seconds hand, while the subdial at 6 o'clock is a totalizer with a 60-minute counter and a 12-hour counter hand set on the same axis. The fan-shaped annual calendar displays, from left to right, the day of the week, the date, and the month.
