Introduced at Basel World in 2011, reference 5270 is the most recent addition to the legendary Patek Philippe perpetual calendar chronograph family starting with the reference 1518 from 1941.

With a thinner case and a 1 mm. increase in diameter over its predecessor (ref. 5970) the 5270 wears quite differently from previous Patek Philippe perpetual calendar chronographs. Another contributing factor to this is the new in-house calibre housed inside, which features a day/night indicator as well as dropped subsidiary dials altering the proportions of the dial.
