Patek Philippe Ref. 5960P-016 Platinum Chronograph

Partially verified

This Patek Philippe reference 5960P-016 is a self-winding chronograph wristwatch housed in a platinum case measuring 40mm in diameter. The movement is the automatic calibre CH 28-520 IRM QA 24H, which incorporates 40 jewels, an integrated column-wheel chronograph with a vertical clutch, and an annual calendar mechanism. This calendar function automatically manages month lengths of 30 and 31 days, requiring a manual adjustment only once per year at the end of February. The dial layout includes a concentric display for the chronograph registers and a power reserve indicator. The timepiece is signed on the case, dial, and movement. The current example is accompanied by its original documentation, including a Certificate of Origin dated 5th March 2014, along with a fitted presentation box, outer packaging, leather wallet, booklets, and a setting pin.

Object description

Case and Dial

The timepiece is presented in a platinum case with a 40mm diameter. The exterior configuration includes the characteristic Patek Philippe chronograph pushers positioned on the case band alongside the winding crown. The case material is identified as platinum.

The dial is black and features applied baton-style hour markers. Central to the display is a concentric arrangement for the chronograph function, which integrates the hour and minute counters. Positioned at the 12 o'clock area are the day, date, and month windows associated with the annual calendar, with a power reserve indicator located below the Patek Philippe signature.

Movement and Technical Features

The internal mechanism is the automatic calibre CH 28-520 IRM QA 24H, containing 40 jewels. This movement powers the chronograph, which uses a column-wheel and vertical clutch system.
