W&W 2022 Patek Philippe Ref. 5172G-010 Chronograph

The CH 29-535 PS caliber, the first classically built chronograph movement entirely developed and produced in-house by Patek Philippe (2009), has been successively offered in various ladies’ and men’s models. In 2019, the Manufacture presented the 5172G model in a white gold case with three-tier lugs, round guilloched pushers and sapphire crystal “box” glass, paired with a blue dial and strap.

Patek Philippe reinforces the vintage spirit of this model, which is by connoisseurs of fine mechanical watches, by introducing it in a new version with rose-gilt opaline dial.

The readability of the dial by day and night is ensured by applied Arabic numerals and charcoal gray syringe-shaped hour/minute hands with white luminescent coating, complemented by a small seconds hand at 9 o’clock. The chronograph features a central charcoal gray seconds hand and an instantaneous 30-minute counter at 3 o’clock. The tachymeter scale printed in black around the rim allows speeds to be measured in conjunction with the chronograph.

The CH 29-535 PS chronograph caliber is distinguished by its traditional architecture (manually wound, column wheel, toothed-wheel horizontal clutch enhanced by six patented innovations, including optimized tooth profiles, improved adjustment of gear penetration and self-regulating reset hammers).

This movement also features several technical features that contribute to the same concern for functionality and performance. Its aesthetics and meticulous finishing are visible through a transparent sapphire crystal case back.
