What reference do we have here? Unfortunately I don’t have a photo of the inside of the caseback but everything looks correct except perhaps the crown. Serial dates watch to early 1950s.

 

That would be my thought as well. I've seen/had these in 14k solid gold as well.

 

but definetely a nice looking dial!

 

Why do you believe it’s a US case? Is it because of a type of screw on caseback design?

 

Typical for watches known to be of US origin.

 

And the lug type is typically found on US watches, in my experience. I don't believe I've seen a 12-sided screwdown caseback before on a Swiss case either.

 

Any guess as to the possible case manufacturer? I know there were a number of them such as Dennison, Wadsworth, etc.

 

I believe this is a Wadsworth case. Steel retainer ring on the back indicates a gold-filled case, solid gold would have a gold ring.

 

Mine says Hi! I also don't know the reference but mine is 14k gold filled. Crown also wrong I believe and has a couple marks on the dial - but not a terrible example nonetheless

 

Very nice. How did you acquire it?

 

e-bay about 4 years ago. Very small so I never wear it but just keeping it for the collection at the moment.

 

Isn’t it 35 mm? If so, it’s not necessarily very small for a dress watch
