Can anyone identify this model?

I’ve recently serviced my vintage omega watch and I can’t seem to properly identify it. I’ve found many similar dials but none exactly like this one. Is the watch legit? The movement picture is a little blurry because it was taken when it was being serviced, but from what i can gather the serial number is 11746551 and the cal. Is 265.

The case reference is stamped inside the caseback. Probably a 2639.

Not all models have names

DON

And if they do, at least the ones I'm familiar with, they usually have names like Candy. Tiffany, Jade, Amber, etc. 😁

So the conclusion is that the model of the watch is stamped inside the case back..reference number..and not all the Omega watches are called "seamaster" "speedmaster" etc..
