Seems like a nice gold filled bumper. Wadsworth case as Dan mentioned so that reference won’t tell you much. Nice, nonetheless.
How do you find a reference number on these 3rd party cases?
14kt solid, can see the lug better here.
That number is a reference number but it’s a Wadsworth reference number. The watch has no Omega reference number.
Okay, I get ya. So Wadsworth would have ordered a dial and movement and built them in locally in the US with their own cases?
It was definitely a partnership between Omega and various local case manufacturers in different countries.
You might find this interesting. Doesn't have your watch in it, but similar.
A dome crown would suit your watch too.

Note how the straps are constructed. You can occasionall find NOS straps on eBay from J-B "Champion" or Kriesler. Note that the strap size to fit that case is likely 11/16 of an inch.
Oh wow, i didn't even think that the strap size wouldn't be metric. but cased in the US in the 50s, sure, that makes sense. I'll keep an eye out for those names.
Since it can be hard to find the strap you want in those odd sizes these days, people will often use a metric strap that is "close enough".

So this?
