BMR seeks community expertise in his quest for a Patek Philippe 5110P, specifically focusing on the challenges of finding a full set in excellent condition. His post highlights a particular watch with unusual wear patterns, prompting a discussion on authenticity, condition assessment, and the value of original documentation in the vintage Patek market.








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.
Hi BMR, I'm no expert and will look forward to other members' opinions as to what to look for when considering this particular Patek, but since it has a deployment buckle, one explanation is that some of the scratches come from the previous owner's ring(s) if he was not careful while scraping the watch on. Nice project BTW !!! good luck in your search. BR,
It is possible that they did a minor polishing on the front and leave the back alone to avoid polishing the hallmark. Anyway, no one ever wear a box or a certificate on the wrist. As long the watch is not a stolen piece , which an archive paper will ease that fear, it is good in my book. I will choose a great piece with no original paper and box then one that's not that great.
This is certainly the other side of the argument, and, likely, the more logical side. After another exchange with the seller, they believe a light polishing was done on the front while the back was left alone. They estimate the watch to be in 80% condition if 100% is new. To further complicate the issue, I have spoken with another seller that has this watch at 95% and is awaiting on an extract. That one would come with extract only, but it is priced 20% less... I think I know which one you would
The seller of this one guesses that the scratches may have come from placing it on a table. I could see that since that would push the deployant buckle up into the case back. I actually don't have any watches with a deployant buckle so I'm not sure if this is a common issue or not.
I will go with the one with only the extract :P The longer you are in this hobby, you will realize the box and paper are over stated. They take up unnecessary space.
going to use the box? If not, the extract signifies that it is not stolen... But there is no right or wrong if you are buying the watch to enjoy and not as an investment Good luck
