Patek Philippe’s reference 5270 perpetual calendar chronograph was introduced in 2011 at Baselworld as the replacement for the reference 5970 first released in 2004. Both models evolved from a line of highly successful perpetual calendar chronographs, starting with the famed reference 1518 – the world’s first serially produced perpetual calendar chronograph wristwatch in 1941, followed by the iconic 2499 released in 1951, and modernized with the reference 3970 from 1987-2004. The reference 5270 broke ground from its historical past, and was Patek Philippe’s first perpetual calendar chronograph wristwatch with a fully in-house movement.

Four years after its launch, the model was introduced with an 18 karat pink gold case, like the present example, in 2015, following platinum-cased models released the year prior. Fitted within a very wearable 41mm diameter case, its dial has a symmetry reminiscent of vintage models, and modernised with a night and day indication. Applied rose gold hour markers and rose gold feuille hands perfectly match the case.

Since its introduction, the model has seen several iterations, as seen with so many of the brand’s past models. The changes have been observed with the dial over three series:

First series: Hands and hour markers are blackened white gold, offering the highest degree of legibility amongst all 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, a tachymeter scale that follows the contour of the subsidiary seconds counter was now added.
Third series: The tachymeter scale now stops where it intersects the timekeeping seconds subsidiary dial.

The present 5270R is presented in exceptional overall condition with all of its original accessories.
