Patek Philippe · Family: Complications
The Patek Philippe 5172G-001 is a 41mm hand-wound chronograph in white gold, with a blue varnished dial and the in-house CH 29-535 PS caliber — Patek's first chronograph movement built entirely in-house, introduced in 2009. It combines a column wheel and horizontal clutch with six patented innovations. Cazador has no verified price observations yet (n=0). Its standout detail: it remains listed on patek.com's active Complications collection as the manufacture's reference dress chronograph.

Patek Philippe introduced the CH 29-535 PS caliber in 2009, a milestone for the manufacture: it was the first chronograph movement designed and built entirely in its own workshops, after decades of modifying third-party bases (Valjoux, Lemania) for its own complications.
The caliber revives the classic column-wheel and horizontal-clutch construction, generally regarded as smoother to operate than the more modern vertical clutch, and adds six patented innovations aimed at improving the accuracy and reliability of chronograph timing, including a braking system for the chronograph seconds wheel.
Reference 5172, launched in 2010 on this caliber, is the collection's two-counter chronograph: a 41mm case that stepped up in size from the historic 5170, proportioned for contemporary wrists while keeping the three-tier lug design characteristic of Patek's Calatrava language.
The 5172G-001 execution, in white gold with a blue varnished dial, sits in the current catalog alongside the 5172G-010 with its rose-gilt opaline dial, both within the Complications family that Patek reserves for watches adding functions beyond hours and minutes — one tier below Grand Complications in the manufacture's internal hierarchy.

Hand-wound. Patek keeps this construction on its reference dress chronograph for its direct link to classic chronograph tradition.
Both share the case and caliber; the documented difference is the dial: blue varnished on the -001 versus rose-gilt opaline on the -010.
A minimum of 65 hours with the chronograph disengaged, thanks to the CH 29-535 PS caliber's mainspring barrel.
No, not in a sport sense: its 30-meter rating covers splashes and rain, consistent with its role as a dress chronograph rather than a tool watch.
Per the patek.com documentation we work from, the reference remains part of the active Complications collection.
