With an illustrious heritage in crafting some of the most revered chronograph wristwatches in history, Patek Philippe once again captured the spotlight in 2010 with the introduction of the reference 5170: the firm’s very first in-house chronograph caliber, CH 29-535 PS. Replacing the earlier reference 5070 (which was fitted with Patek Philippe’s last Lemania-based caliber, CH 27-70), the new movement took five years to develop and incorporated six innovative patents, all while preserving the traditional column-wheel architecture.
The ref. 5170 features a refined Calatrava-style case measuring a comfortable 39.5 mm in diameter, compared to the larger 42 mm case of its predecessor. The present example is cased in yellow gold and notably fitted with a pulsometer scale on the dial — a charming nod to doctor’s watches of the 1940s that lends the piece a touch of vintage character. Despite its reduced practicality, the ref. 5170 remains a timeless classic distinguished by its excellent legibility, elegant proportions, and versatile appeal suitable for both formal and casual wear.
