Patek Philippe introduced the reference 5370 in 2015, and it made an immediate impact thanks to its classic design (that not so subtly recalls the Patek 130, the ref. 1563, and even ref. 1436) and refined in-house manually winding caliber CHR 29-535 PS, the base caliber of which made its debut in 2009 as the brands first entirely in-house manually winding chronograph movement. The black or blue enamel dial features applied Breguet numerals, oversized registers on either side of the hand stack to track the running seconds and totalize the minutes, and a prominent tachymeter bezel running the perimeter. This is a pure split-second chronograph with no superfluous complications at work, and it’s an absolute wonder.
The reference 5370 represents a new generation of an important lineage for Patek Philippe. It also establishes the brand’s mechanical prowess with its own highly impressive (not to mention beautiful) caliber, no longer relying on Lemania-based movements. This watch is the best of the brand’s past while showcasing what to expect from the brand moving ahead. This purity of character draws people into the true magic of Patek Philippe, and it’s one of their finest modern references.
