Patek Philippe’s 5960 is the first self-winding chronograph with an Annual Calendar and the manufacture caliber CH 28-520 IRM QA 24H. The Latest platinum version with the blue dial emphasizes the dynamic personality of this timepiece.
This is definitely not your Dad’s Calatrava; it is not even just a watch. The reference 5960 is a statement; a testament to Patek’s heritage, a reflection of Patek’s confidence in its leadership position in the industry, and a glimpse at the future, all in one spectacular wristwatch.
Where do I even start, in describing Patek’s newest masterpiece: the reference 5960 P annual calendar chronograph? Let’s start with history: this is Patek Philippe’s first automatic chronograph in their 167 year blue-ribbon history. It’s also Patek’s first flyback chronograph. And, due to the caliber’s unique construction, the central chronograph seconds hand can be operated continuously (to serve as a conventional seconds hand) without harming the mechanism or adversely affecting accuracy.
The reference 5960 also features the first completely in-house chronograph caliber from Patek since the early 1980s. (In the interim years, all of Patek’s chronograph calibers have been built from Nouvelle Lemania ebauches). Finally, this chronograph is the first to feature the 30 minute and 12 hour chronograph indicators in the same subdial. So clearly, Patek has innovated meaningfully with their new automatic winding Caliber CH28-520. But we’ve only covered the chronograph so far…
This newest Patek Philippe masterpiece also provides an annual calendar, with the day, date and month displays arranged in an arc from 10 o’clock to 2 o’clock. Within the chronograph subdial there is a small aperture which displays a day/night indicator. To round out the complications, a power reserve indicator is located just underneath the date window.
