The most iconic piece amongst Patek Philippe production is probably the perpetual calendar with chronograph.
The current model, the reference 5270 was first introduced in Basel in 2011. It is distinguished by the new in-house calibre CH 29-535 PS and the subisdiary dials located below the central axis of the dial. In comparison with the previous model, the reference 5970, it also has a larger case (41 mm). 

The 5270 is divided into three series:
- the first series, the "sleek", like the present lot, only available in white gold with satin silvered dial and black-oxidized gold hands and indexes was produced in 2011 and 2012. It is characterized by its excellent legibility thanks to the absence of tachymeter scale.

- the second series, the "chin", available in 2013 and 2014 only in white gold with silvered or blue dial is easily recognized by the shape of the date track looking like a face with a chin. It also features a scale for the seconds and the tachymeter.

- the third series, the "double scales", introduced in 2015, is available in three different combinations: in white gold with either a silvered or blue dial and in pink gold with a silvered dial. This series can be identified thanks to its two outer scales, for the seconds and the tachymeter. The date track is round as for the first series.

The Patek Philippe perpetual calendar with chronograph from all periods have become highly sought-after by collectors around the globe and the new reference 5270 is already considered as a modern classic. The present lot, from the first year of the introduction of the model with its very desirable "sleek" dial is a particularly appealing example.
