Considering a purchase of a 2639-13, need advice/help please

I am considering a purchase of the following watch and could use some advice as my knowledge of vintage Omega's is poor to none. I would greatly appreciate any input.

I have only recently been looking at vintage Omega's and my reason for looking at this particular watch was the year is special to me and I like the style of the watch. I have seen watches of that year in better condition but are out of my current price range. I actually like the patina on the dial but should the oxidisation on the dial be a concern?

My main concerns are, am I over-paying for the watch by a huge amount and are there any obvious alarms bells that would make this a bad purchase.

Thanks in advance for any responses.

The watch details are as follows:

Price is $750
Omega 2639-13
Year 1952
Case size 36mm
Last service 2020

if you really like the watch then you should go for it.
you are going to loose money but i does not matter if you are going to keep it for a long time

Thanks all for the considered advice.

Think I will exercise some patience and wait for something better.
