The Patek Philippe reference 5170 was introduced twelve years ago, as the latest chapter in a legacy of manually wound, two-register chronographs. Replacing the Lemania-powered 5070, the reference 5170 was originally produced exclusively in yellow gold, as the 5170J, before later adopting the grey-gold case featured in this example, the reference 5170G-001*.

Reminiscent of a vintage Patek Philippe ref. 130, the reference 5170G-001 is designed in a similar vein to admired Patek Philippe chronographs of the 1940s, displaying straight hands, with a white dial and applied, oversized Breguet numerals. The watch is also classically sized at 39.4mm in diameter, fitting neatly underneath a cuff.

Notably, the reference 5170G-001 displays a pulsometer, a feature used in early “doctor’s” watches, further adding to the watch’s vintage appeal. Overall, the dial layout is cleanly designed, with the chronograph highly legible in a variety of lighting conditions. The 5170G-001 also has a stop-seconds feature, making accurate synchronisation easier when the crown is pulled.

The watch integrates Patek Philippe’s very first in-house chronograph movement, boasting several patented innovations and technical refinements, designed to improve functionality and dependability, over that of previous Lemania-based calibres. The calibre CH 29-535 PS movement is based on the classic architecture of column-wheel control – a hallmark of many great mechanical chronographs.

Closer look

This Patek Philippe 5170G is in very good condition overall, with a few minor superficial marks visible on the case consistent with light wear over time. The most notable of these imperfections is a small hairline imperfection seen on the outer left lug at the 7 o’clock position. The dial, hands and movement are otherwise free of any blemishes.

The watch comes with a two-year warranty from A Collected Man, alongside a lifetime guarantee of authenticity.
