Mark in Paris shares his detailed impressions of the Patek Philippe Ref. 5170J chronograph after experiencing it in person. Initially skeptical, Mark's hands-on encounter transformed his perception, leading him to appreciate its timeless design, exquisite dial finish, and refined movement. His review offers a valuable perspective on how a watch can evolve in a collector's esteem once seen beyond photographs.







The Patek Philippe reference 5070, part of the Complications collection, marked a significant return for the brand to large-format chronographs. Introduced in 1998, it was the first non-perpetual calendar chronograph produced by Patek Philippe since the reference 1463, which ceased production in the early 1960s. Its design drew inspiration from a unique Patek Philippe aviator's watch from the 1940s, characterized by its prominent case and dial layout, yet reinterpreted for a contemporary audience. This reference established a new aesthetic direction for the brand's chronographs, moving towards more substantial case dimensions.
The watch features a 42mm case, initially offered in 18k yellow gold, housing the manual-winding Caliber CH 27-70. This movement, based on a Nouvelle Lémania ébauche, was extensively finished and modified by Patek Philippe, meeting the brand's stringent quality standards. It provides a power reserve of approximately 55 hours. The dial, in this specific configuration, is black, protected by a sapphire crystal, and the watch is water-resistant to 30 meters. The fixed bezel frames the dial, and the watch is typically fitted with a leather strap.
Reference 5070 appeals to collectors interested in modern Patek Philippe chronographs that combine traditional movement architecture with a more contemporary case size. Its limited production run and the subsequent introduction of variants in other precious metals contribute to its collectibility. The reference represents a distinct period in Patek Philippe's chronograph history, bridging vintage inspirations with a new era of larger watch designs.
As for the movement, I still don't know what to think, but the case, dial and hands on the 5170 don't convince me at all. The 2 subdials seem to be not centered, a bit lower than the " middle lane ". The hands are less refined than those of the 5070, as well as the case. But we are not obliged to have the same tastes, sometimes. ;) Thank you spo much for this excellent article, Mark. Best, Nicolas
I like 5170 more and more and the movement is a real marvel. What I do not like are the Roman numbers on the dial. I have been tempted to get this watch but I have decided to wait till some white versions are coming to the market. Thank you for a great post! Best, Kari
The 5070 gets my vote by far But that doesn't mean I don't like the 5170. In fact I love it. I saw it more than once irl and if it was not so expensive I would start saving. But today Patek watches became too expensive for me :-( But like Nicolas said, the case, dial, hands of the 5070 are imo better and I also don' t like these sunken subdials. But than again, I would be VERY happy if I could ever afford a 5170. Imo much better than the Dato, much better than the 5980 and much better than any c
I am speechless and can't stop watching the screen... Its amazing watch and which is most important its a everyday watch for any occasion
write your thoughts & observations regarding the 5170J. :) The photos were nicely taken. Now, the question is did you buy it? Regards Tony
It is a great watch and mine gets quite a lot of "wrist time". Thanks for sharing those cool pictures! Best regards Georg
