Catalogue Essay
A worthy heir to the Patek Philippe split-seconds chronographs of yesteryear, the reference 5370 was first introduced in 2015 to vivid enthusiasm from Patek enthusiasts. The 41mm platinum case draws inspiration from the most classical of vintage Patek Philippe chronographs, the reference 130, famously rendered in a split-seconds version as the reference 1436 (for an example of a vintage reference 1436, please see lot 106). The architectural cues remain in the elongated lugs, polished bezel, while boasting an increased diameter and prestigious platinum case material with sapphire caseback, by which the superbly finished caliber can be viewed. Interestingly, the hand-polished case has an inset brushed panel, and the location that would normally feature a lug hole instead has a platinum cabochon. According to Patek Philippe, the entire case finishing process takes one artisan three hours to complete.

At first featuring a black enamel dial, the fully in-house manufactured and finished caliber CHR 29-535 featured a brand-new isolator that uncouples the split-seconds wheel from the chronograph wheel thus eliminating friction. Furthermore, the brand developed an ingenious system allowing the chronograph and split seconds hands to perfectly align upon resetting to zero. In 2020, the black enamel dial was discontinued and the reference was relaunched with the intense cerulean blue dial of the present example, and this is the first of its kind to grace the auction market.

Retaining all of its original accessories, including additional solid caseback, this is the first-ever opportunity to acquire a 5370P-011 publicly, and for many, a very rare opportunity to acquire one at all considering its extremely low production numbers.
