Patek Philippe Perpetual Calendar Moonphase Chronograph Reference 5970P

Partially verified

The Patek Philippe reference 5970P is a perpetual calendar chronograph wristwatch featuring a 40mm platinum case. Produced in 2010, this model represents the fourth installment in the Patek Philippe Grand Complications perpetual calendar chronograph line, succeeding the reference 3970. The timepiece is characterized by a slate black dial with platinum markers and square-shaped pushers for the chronograph function. It is powered by a modified non-in-house caliber movement, which the source notes was replaced by in-house movements in subsequent references. The case design incorporates a diamond stud at the 6 o'clock position to signify the use of platinum. The watch is accompanied by an original black crocodile leather strap with a platinum deployant clasp, a chocolate brown alligator strap, and a complete set of accessories including a secondary solid platinum case back, the Certificate of Origin, and additional factory packaging.

Object description

Case and Dial Design

The reference 5970P features a 40mm platinum case, which the auction description reports remains unpolished. The case geometry includes square pushers that serve as an aesthetic reference to the 1941 reference 1518. A singular diamond stud is set into the side of the case at the 6 o'clock position, acting as an identifier for the platinum construction.

The dial is slate black with applied platinum markers. Functions include day and month apertures positioned below the brand signature, a 30-minute totalizer with a leap year indicator at 3 o'clock, a running seconds and 24-hour indicator at 9 o'clock, and a moonphase display combined with a radial date scale at the 6 o'clock position.

Evidence for this section
  • “The platinum case is simply phenomenal”
  • “The square pushers are original as is the winding crown adorned with the Patek Philippe cross”
  • “The original slate black dial with platinum markers is flawless”

Movement and Series Evolution

The reference 5970 marks the fourth generation of the Grand Complications perpetual calendar chronograph series. It serves as the bridge between the 3970 and the 5270. According to the provided information, this reference is one of the final models from Patek Philippe to utilize a modified, non-in-house movement before the transition to the reference 5270 in 2011.

The movement employed in the 5970 line is derived from the Lemania 2310, an architecture noted for its history with the NASA Apollo missions. Patek Philippe performed significant modifications to this base movement to include the perpetual calendar functionality and to meet their own internal finishing requirements.

Evidence for this section
  • “The fourth installment of the Patek Philippe Grand Complications Perpetual Calendar Chronograph is the reference 5970”
  • “The Lemania cal. 2310 is widely regarded as one of the greatest movements ever created”
  • “This transition makes the ref. 5970 very likely the last Grand Complications reference made with a modified non-in-house movement”
