Patek Philippe

Following ten years of predominantly dress-watch-like annual calendars, the Reference 5960P was launched in 2006.

On this occasion, the manufacture introduced its first industrially finished automatic chronograph movement. The calibre CH 28-520 IRM QA 24H (with Patek’s Spiromax spiral), which was created entirely in the Patek ateliers, from development of the movement to the finished calibre.

The Ref. 5960P unites a mechanical flyback chronograph and an Annual Calendar, two of the most popular complications in timekeeping. The calendar mechanism is based on a patent granted to Patek Philippe in 1996 for the Annual Calendar.

The upper half of the dial of the Ref. 5960P is dedicated to the Annual Calendar that displays the day of the week, the date, and the month in three apertures arranged along an arc from 10 to 2 o’clock. The date at 12 o’clock is very prominent. With its polished white-gold frame, the date aperture creates a subtle visual balance with the totalizer that dominates the bottom half of the dial. Depending on the state of wind of the mainspring, the small hand of the power-reserve indicator below the date aperture moves between the plus and minus symbols.

The present example, cased in platinum, is complete with all accessories and is presented in good condition
