Congrats, this watch is incredibly beautiful.... are you French? I was registered to bid hoping it would stay under the radar but it exceeded my limit by several fold...

I have no doubt the dial is original.

As for the “PGF” mark, the author of “Vintage watch ressources” website heard from a jeweler that it could refer to a case maker named “Paul Frank”.

Is that the one to which you are referring @François Pépin and @dodo44 ?

As has already been said, some gold cases with that logo also bear the Longines and Omega markings.
See the pictures and links below.

Yes it's already done, I'm waiting for their reply.

To @DirtyDozen12 : you're right about the movement... it seems there are at least two versions of 23 M movement : one version for central second and one other for the small second at 6 o'clock... and maybe others...

with small second :



with central second :




To @Syrte : Yes I'm french
And thanks for your interesting information about Paul Frank !!

 

Update after receiving an email from Longines this morning :

"Originally, the serial number 7'467'151 identifies a mechanical Longines movement with manual winding, caliber 23M. It was invoiced on May 18, 1948 to our Longines subsidiary in France.
The other parts of the watch were manufactured locally under Longines license. Unfortunately, since we do not have the records in our possession, we are not able to give you more information about your model."

So it's a caliber 23M (congrats @DirtyDozen12 )

According to the email of Longines I conclude the watch is all original : all is well that ends well !!

Again, thanks a lot for your help !

 

Incredible watch, as others have stated. Congrats!

 

As I said a week ago

 

gorgeous piece. great find

 

wow, what a stunning watch, great size too !

 

Holy shit, this is one of the best watches I've ever seen!

Did the original owner put it in an airtight box, in bank vault?

 

What a stunner!

 

I realize I commented on this before but I had a look at it again and noticed I couldn't close my mouth. What a beauty. A real time capsule.

 

Concerning PGF... Actually I made an intensive research concerning that maker. Funnily I saw sometimes signs other OF members did the same (@mondodec)!

I have not identified this maker. But I have reached the following conclusions:

i) PGF made cases for many brands, including Omega, Longines, Cyma. The case back could have the brand logo (the old one for Omega) or not.

ii) PGF is, actually, not PFG but PF with a maker logo. I have searched in the French official data base for gold makers. No PGF. Plenty of PF. And it is normal practice to put a logo between the initials. Having a logo was mandatory and it has to be registered.

iii) I have checked all the registered PF and could not find the correct one. But for many of them I had only a description of what the logo was supposed to represent, but no pic of this logo. So not easy! I have tried to google all the names of the makers whose initials were PF (about 15 names), but could not find our guy.

iv) I have spent too much time looking for this info, but will very likely continue!

 

As amazing as it seems, here’s another one of those hitting the market.... it would be interesting to see if the case is made by the same maker.

 

Longines signed case according to the seller.

 

Wow! That's a supernice Longines, congrats to OP

 

A correction, I found out the IG user named @vintage_watch_longines who posted this is not the author of the website, even though he puts up the link in the « bio » section of his profile.
The website author is a friend of his (in California).

 

Beautiful vintage timepiece! Wear in good health.

 

Let’s start with NFW - congrats!
