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 three series. The dial features railway minute divisions combined with Arabic five minute divisions and was produced from 2011-2013. (The present example)

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 present example Patek Philippe ref. 5270G-001 from circa 2012 belongs to the highly desirable first series. Featuring a brushed silvered dial with blackened white gold baton indexes and leaf hands, the appeal of the present timepiece is arguably one of the most attractive configurations of the reference. Offered in excellent overall condition, this fresh to the market example is further complete with its full set of accessories including its additional solid numbered caseback and setting pin.
