Patek Philippe 5172R-001 houses the manually wound Caliber CH 29-535 PS, featuring a column-wheel chronograph system with horizontal clutch. The 41 mm rose gold case is paired with a black dial incorporating a tachymeter scale and applied gold Arabic numerals. The movement operates at 28,800 vibrations per hour and provides a power reserve of approximately 65 hours, supporting precise chronograph engagement and reset.

With its warm rose gold construction and mechanically robust movement, the 5172R-001 delivers both performance and visual strength. It is suited for collectors seeking a chronograph that combines technical consistency with a more pronounced presence.

Alternative References & Configurations

The 5172 family has been produced in several documented configurations:

* 5172G-001 — 18K white gold; blue varnished dial; navy-blue calfskin strap; Calibre CH 29-535 PS.
* 5172G-010 — 18K white gold; later dial/strap configuration; Calibre CH 29-535 PS.
* 5172R-001 — 18K rose gold; silvery opaline dial; brown alligator strap; Calibre CH 29-535 PS. Primary configuration.
* 5172R-010 — 18K rose gold; later brown-dial configuration.
* 5172R-001B — documented bracelet configuration of the 5172R family.

The primary 5172R-001 should therefore not be confused with the later 5172R configurations, particularly where dial and bracelet/strap execution differ.
