Patek Philippe

I don't think it is a replacement dial.

 

Usually when one has an official replacement dial, it will be of a later model. What I am afraid is it is a swap dial from dealer. For example, I have seen late Patek 570 (1969) watch with early 570 raised enamel signature dial (before 1966). Dealer insists that it is authentic and real. After some deep investigation, I found the picture of that exact watch before the dial was swapped. They share same archival extract.
Then again, yours could be an early 3rd series and they decide to use the remaining 2nd series dial on yours. I would think this is the case. I honestly don't think any dealer would want to swap a dial that belongs in the 90s.There is nothing to gain. In short, I think this dial is legit on your watch and nothing to worry about.

3940 Question/Concern

 
By: GUZZ : April 19th, 2020-14:25
Hey all! I recently read a great article on Watch Brothers London about the differences between the series of 3940. This got me looking at my own 3940G which I've had a few years. According to the article all 3rd series watches have the sigma markers in l...  

Did you check your serial number?

Your Sigma belongs to first series and second series. Does the '9' in your watch connect? If it does, it belongs to series 1. Are you the first owner?

Mine’s from 2004 and has the APRIOR inline with the minute markers, so it is indeed odd that yours does not. However, based on my humble opinion... (1) you sent it in to Patek for a service, and if it didn’t come back with any remarks, I think you’re good... 

Zero cause for concern.

I've seen plenty just like yours. As Mike said, there's a lot over overlap between series. The only rule is there is no rule.

Sam is correct

J without the top lid is indeed an indication of later examples. Like how you will see on the 5140 and thereafter

Thank you for these articles!

The ACM and Watch Brothers London articles have been a great help as I begin my search for a 3940. I'll pose questions and thoughts in a separate post.
