Patek Philippe 5107 Case Number Location??

 

Hi all,.....I have a Patek Philippe 5107-J Calatrava that I wish to extract an "Extract from the Archives", as I can't seem to find the original certificate since we moved back in 2005.

 I may be selling this over the next several months is the reason I wish to get "some" paperwork on it,.... to alleviate any potential purchaser's question as to authenticity.

 I had assumed the movement number was likely to be the same as any case number (like on some vintage Patek's),  but I can't seem to find any case number showing from anywhere visible without opening the case.

However, I did see a copy of a Patek Philippe  "Extract from the Archives" on a current ebay offering of this model, and there IS definitely a spot shown on that document with a case number that is different from the movement number.

So just WHERE is the case number located on this model?  (and of course only accessible with back removal which is unnecessary and impractical imo! :-( 

thanks,
Joe T

This is a very nice Calatrava model you have. Well, concerning your question, the case number seems well hidden indeed. I never heard about it and I guess you already looked between the lugs, otherwise it might indeed be inside the case... I don't know wh...

Just to confirm from another source. I have a 5107g with an extract from the archives, the case number is indeed different from the movement number. I also cannot locate the case # on my watch. When you do resolve this issue please share it with the forum... 

Hope you'll get the answer when Joe gets it.

And welcome on our forum! By the way, the movement number is based on a different sequence and is always different from the case's. Please feel free to share some pictures if you can, it is a rare reference :) Cheers, Mark

Thanks,...and some pics

Thanks for the responses,......even though I was hoping there was "some" place on the outside or visible on the inside of the case through the saphire back that would allow seeing the case number required to get an Abstract from the Archives. Geeze,.....I...  

Those pictures are great Joe

The watch looks gorgeous and in very good shape. Thanks for having taking the time to share some pics so quickly :) As for you case number, it seems difficult indeed. At least you can call them to be sure the number is inside. Then, finding someone with t...

On my 5146, the case number is stamped on the inside of the caseback/sapphire glass ring. It's possibly the same with the 5107 and most other newer Pateks with sapphire backs. ...  

So is that the back side of the case back ring or......?

Hi,...it looks to me as if your pic is showing the reverse side of the gold ring that holds the sapphire back crystal in place,.... is that correct? If so that surprises me, because then the "case" number actually follows a removable ring. So I don;t thin...
