We have always seen different hallmarks on various Patek watches, especially the old ones. hey are usually placed under the lugs, on the case side or on 6 o'clock case side. I'm curious how important are the hallmarks to you when you acquire a piece. And when it is not as important. For example, when I purchased a Patek 2526, I was focusing on the perfect enamel dial and give less priority on the case hallmarks. When I research on 3448, my focus will be on the lugs' sharpness and the chamfered edges. But what about you?

Also, I have attached an image of these lugs. What do you think? Are they considered prominent and deep?

About the Patek Philippe 2526 Ref. 2526

The Patek Philippe Reference 2526 is notable as the brand's first serially produced automatic wristwatch. Introduced in 1953, it marked a significant technical advancement for Patek Philippe, housing a self-winding movement at a time when manual-wind mechanisms were still prevalent. This reference is recognized for its clean aesthetic and robust construction, establishing a foundation for future automatic timepieces from the manufacture.

The watch features a 35 mm case, available in 18k yellow gold, 18k rose gold, or platinum. It is powered by the caliber 12-600 AT, an automatic movement with a Gyromax balance and a solid gold rotor, offering a power reserve of approximately 40 hours. The crystal is acrylic, protecting a silver dial that often features enamel. The case design is characterized by its smooth bezel and often includes a screw-down case back, contributing to its water resistance.

For collectors, the Reference 2526 is highly sought after due to its historical significance as Patek Philippe's inaugural automatic model. Variants exist with different dial configurations, including those with applied indexes and small seconds, which can vary between the gold and platinum versions. The presence of original bracelets, particularly on rose gold models, can also add to its collectibility, as these were less common than leather strap configurations.

Key Points from the Discussion

The prominence and depth of hallmarks can vary even on unpolished watches, as they were hand-stamped and could differ in crispness by year of production or case metal (e.g., less prominent on platinum than gold).
Assessing case condition, especially on references like the Patek 3448/3450 with their unique lugs, requires close examination of sharpness and chamfered edges to detect polishing, which can round out original features.
Many vintage watches on the market, especially those from the 80s and earlier, come with issues like over-polished cases, missing paperwork, incorrect boxes, or dubious service history, making due diligence crucial.
The vintage watch market is susceptible to hype and unscrupulous practices, including dealers who 'age' dials or auction houses that misrepresent condition or create 'ultra rare transitional versions' to inflate value.
Collectors should be wary of dealers who make false claims about a watch's condition, as many watches described as 'Like New' arrive with significant scratches, underscoring the importance of trustworthy sellers.
Auction houses often prioritize consignors over buyers, and some have been known to dispute legitimate claims about misrepresented items, making them risky avenues for acquisition.
Inexperienced collectors are often targeted by dealers as 'fresh meat' due to their lower demands and faster decision-making, highlighting the need for extensive knowledge before purchasing vintage pieces.

That's considered a somewhat polished out.

I wouldn't consider those hallmarks to be deep.

Thanks...

Is this considered bad or acceptable? My 2526's hallmark has no detail at all. In naked eyes, these hallmarks look deep and prominent. Only upon marcro photograhy we start to sense more. So do we judge hallmarks y naked eyes or do we use extreme closeup? What's the usual practice?

"Bad or Acceptable" is an opinion...

It depends on who owns the watch, if they find it acceptable or not. I find it to be a beautiful watch from what I can see, but I'd just be concerned if any of the other sharp corners have been "rounded" from the polishing and wear over the years. That's all. My Patek Philippe Nautilus is perfectly acceptable to me. It's never been polished but might have a few fine hairline scratches. It might be deemed "bad" by some people. But it's good in my eyes. You also need to compare it with identical w

Hand stamped...interesting. Thank you.

Always wonderful to learn something new . I'm pretty confident at checking corners and edges... just no experience in seeing hallmarks as I rarely look at them these closely. I usually just inspect it with naked eyes and if I can see the shading and shadow of the engraving, I just move on.

Details of hallmarks could only be deciphered by a loupe and not with naked eye

The pic you showed would be consistent with nice clear hallmarks If this were a piece from 60s, 70s and evening 80s in my opinion

This example is from 90s.

Those I had seen recently in the 70s and 80s all look soft when I see with a loupe. Now I will always use a loupe and see these hallmarks
