Patek Philippe Ref. 5170

The genesis of a new classic

It takes audacity to call a new watch a classic, but in the case of the Patek Philippe chronograph Ref. 5170J, the attribute is justified. Although it debuts at Baselworld 2010, it has already been at the top of the wish list of many collectors and aficionados for many years – and a popular topic among specialized publications. Now, the time for speculation is over and the object of desire has become reality: the classic men’s wrist chronograph developed entirely by Patek Philippe and crafted exclusively in the manufacture’s workshops.

Patek Philippe Ref. 5170Patek Philippe spared no effect to exceed all expectations with its new classic wrist chronograph. Indeed, the development of the CH 29-535 PS movement took more than five years, spanning several stages that also embraced further chronograph calibers including, in 2005, the CHR 27-525 PS with a height of just 5.25 mm: it holds the world record as the thinnest split-seconds chronograph movement with column-wheel control. The new chronograph movement inherited its chronograph wheels with the patented tooth profiles. In 2006, the workshops presented the self-winding Annual Calendar chronograph with a disk clutch that delivered further important insights regarding power flows and amplitude characteristics in chronographs. Finally, five further inventions were incorporated in the new caliber CH 29-535 PS to achieve the desired degree of perfection.
