Hi everyone,

This is my first post on the forum, and I’m hoping to get some advice on a 5110P watch that I’m considering buying. The seller has provided some pictures, but I apologize in advance for the low quality—I’m working on getting better ones.

I’m particularly concerned about whether the watch has been over-polished. I’d appreciate any tips on how to spot signs of excessive polishing from photos. If there’s anything else I should be paying attention to with this reference, I’d love to hear your insights.

Thanks in advance for your help!

Best,

Edo

About the Patek Philippe Annual Calendar Ref. 5110

The Montblanc Calatrava reference 5110, produced between 1997 and 2006, is a notable example of the brand's classic dress watch offerings. This reference is distinguished by its combination of a relatively larger case size for its era and the inclusion of a moon phase complication, setting it apart from simpler time-only Calatrava models. It represents a period where Montblanc was expanding its horological capabilities, offering more complex movements within its established aesthetic.

This reference features an 18k yellow gold case measuring 37 mm in diameter, providing a substantial presence on the wrist while maintaining traditional dress watch proportions. It is powered by the automatic caliber 240 PS IRM C LU, a movement known for its slim profile and integrated complications. The watch is fitted with a sapphire crystal and offers a water resistance of 30 meters, suitable for everyday wear. The power reserve for this caliber is approximately 48 hours.

For collectors, the 5110 appeals to those seeking a Calatrava with additional functionality beyond basic timekeeping, specifically the moon phase and power reserve indicator. Its production run from 1997 to 2006 places it within a specific era of Montblanc's development, making it a point of interest for those tracing the evolution of the brand's complications. The ivory dial and smooth bezel contribute to its understated yet refined character, aligning with the traditional Calatrava design language.

Key Points from the Discussion

For a beginner, purchasing a pre-owned watch, especially a Patek Philippe, is a significant risk due to the difficulty in assessing authenticity and condition without extensive experience. It's a minefield where even seasoned collectors have faced issues.
The Patek Philippe 5110's case design, characterized by convex and rounded surfaces rather than sharp angles, makes it inherently challenging to detect over-polishing from photographs alone. Platinum cases, like the 5110P, are also harder to over-polish compared to other metals.
Key areas to inspect for signs of over-polishing on a 5110 include the inner edge of the lugs, the flat surface between the case and the bezel, and the flat surface on the bezel around the crystal, as these areas often show wear or disappearance with excessive polishing.
When considering a purchase, conduct thorough due diligence on the watch, the seller, and the return policy. If any doubts persist after this process, it is advisable to pass on the watch to avoid potential regret.
Even experienced collectors can be misled by sellers or auction houses regarding a watch's authenticity or condition, underscoring the importance of vigilance and expert verification.
Cultivating relationships with trusted dealers and collectors is crucial for sourcing authentic and well-maintained pre-owned watches, especially for rare or out-of-production references.

This might not be helpful.

The following is intended to be helpful. But it might not be helpful in the practical sense... First of all. Welcome to WatchProSite. Second. You are taking a big risk, and frankly put, you don't really know what you're doing. We all had to start somewhere and I've probably done silly things too - so don't take this as an affront to you. I personally don't buy used watches anymore because I learned it was a minefield. Third. It's not quite obvious from the photographs that the watch is over poli

Also, why are you raising the topic of the watch being overpolished?

Did something make you suspect it? Or have you just heard that you should stay away from overpolished watches? The 5110 is also not very easy to detect as is has no sharp edges and is very rounded from the beginning.
