Help with this watch

I’m looking at buying this watch it’s from a private seller. I know the watch is 1964 by the serial number I can’t figure out much more. Any help to point me in the right direction on learning more or how much I should pay would be appreciated

The 26x series of handwinds was the final hurrah for the venerable 30mm series of watches created 25 years earlier. Search Omega 30 T2 to learn more. I’ve owned a 265 and a 267, both were a relatively larger size than many vintage handwinds, they’re rock solid runners, wind and set smoothly. As for the piece you show it has a nice patina on what appears to be an original dial, a large six-eater subseconds, a perhaps overly-polished stainless steel snapback case and a pretty clean movement. Personally I would ask for a higher resolution dial shot and a scan of the inside caseback. Price in the $500 - $750 range would seem reasonable.

Thank you for your advice I got some more pics

Now search 121.001 and you’ll learn quite a bit more of this reference.
