Catalogue Essay
The serially-produced perpetual calendar chronograph is one of Patek Philippe’s most historic and iconic models to date. Its roots date back to 1941 with the creation of the reference 1518. The reference 5270 is the latest version of this complication by Patek Philippe, following the 1518 (1941-1951), the 2499 (1951-1987), the 3970 (1987-2004), and finally, the 5970 (2004-2011) that marked the end of the era of Patek Philippe’s use of outsourced – and superbly modified - movements for the base chronograph calibers.

The reference 5270 was a truly ground-breaking successor to the brand’s storied perpetual calendar line. With its launch in 2011, it was Patek Philippe’s very first perpetual calendar chronograph with a fully in-house movement. There are three recognized series of the 5270, which are as follows:

First series: the hands and numerals are blackened white gold, offering the highest legibility among all the three series. The dial features railway minute divisions combined with Arabic five-minute divisions and was produced from 2011-2013.

Second series: in production from 2013 to 2015, the hand and numerals are now a more classic white and the tachymeter scale has been added. The scale follows the contour of the subsidiary seconds counter.

Third series: The white numerals and hands are unchanged, but the tachymeter scale now stops where it intersects the running seconds subsidiary dials. The current production 5270 is no longer available in white gold.

The present first-series example is fresh-to-the-market, accompanied with its additional solid caseback, setting pin, certificate of origin, product literature, and original packaging in pristine condition. A part of the Ride the Wave collection, it was acquired directly by the collector at the Patek Philippe Salon in 2012 and is truly a superb example of the earliest iteration of this milestone reference.
