Have you ever walked into a Patek boutique just to talk to the sales associate and perhaps look around at what's on display - not interested in any watch in particular? I did this a few years ago in Qatar. Since I don't live full time in Doha I don't expect to be offered a watch so there's absolutely no stress. It's a wonderful frame of mind to visit a Patek boutique with no motivation to hunt or buy. I simply wanted to be in the presence of Patek Philippe, enjoy a coffee and talk watches with the outstanding staff - maybe some current events, light hearted politics, etc. On this particular visit I noticed a 5370P in the most lux showcase area of the boutique. Having nothing to lose and feeling very loose and happy I asked if I could see the watch.

What an absolute treat! I would've preferred looking at the black enamel dial version but the blue was ELECTRIC, deep and mesmerizing.

Does anyone own this specific reference? Do you get to wear it often and is it fun to wear?

Best,

Robert

About the Patek Philippe Split-Seconds Chronograph Ref. 5370

The Patek Philippe Reference 5370 is a split-seconds chronograph, a complication highly regarded in horology. It stands out in the Patek Philippe collection for its focus on a technically demanding chronograph mechanism without additional complications, presented in a classic and refined aesthetic. This reference appeals to collectors who prioritize mechanical complexity and traditional watchmaking.

The watch features a 41 mm case, available in either 18k white gold or 18k rose gold, with a polished bezel. It is equipped with the manual-winding caliber CHR 29-535 PS, a movement known for its innovative split-seconds mechanism and column-wheel control. The power reserve is approximately 65 hours. A sapphire crystal protects the dial and offers a view of the movement through the case back. Water resistance is rated at 30 meters.

This reference is notable for its enamel dial, offered in black or white, which provides a depth and finish characteristic of high-end watchmaking. The 5370 appeals to collectors seeking a pure expression of a grand complication chronograph from Patek Philippe, valuing its technical execution and understated design. It represents a significant offering within the brand's complicated watch lineup.

Key Points from the Discussion

The Patek Philippe 5370P, while a lovely watch, can feel top-heavy due to its platinum case, 41mm diameter, and 13.56mm thickness, despite the movement being commensurate with the case size.
The blue enamel dial of the 5370P is considered by some to be the best blue dial available, consistently tempting collectors who have tried it on.
Despite its substantial feel, the 5370P is described as a versatile watch that gets significant wrist time, feeling modern and casual, making it fun to wear.
Aesthetic preferences vary, with some collectors initially favoring the black dial but later reconsidering the blue, while others suggest the watch would be 'perfect' if the subdials were sunken and aligned at 3 and 9 o'clock.
The visual impact of the 5370P is difficult to capture in photographs, as its 'pops' and must be seen live to be fully appreciated.
For collectors with smaller wrists (e.g., 16 cm), the 5370P, despite being a 'grail-level' watch, may be perceived as too large.

What a beauty...

I don't own one but, for me, it has the best blue dial. Tried it on many occasions and always very tempted.

Hi Robert, I saw this piece in the metal previously and the blue dial really

POPS ! Hard to describe because it must be seen live 😇

Funny thing (with me) about super attractive subjects...

in the moment I think this thing is so beautiful that it's impossible to take a bad foto. Then later when I'm looking at the foto I took - I'm disappointed that I didn't take more effort to capture it better. Best, Robert
