The serial number dates the movement to the late 1940's, but I can't find any mention of reference number W160706. It's a nice looking watch. I'm hoping to determine which model it is.
Thanks in advance,
TQ

US-cased watches don't have the usual Swiss reference numbers.

I think that W number is Wadsworth case SN.

They made pocket watch cases for US brands such as Hamilton and Elgin.

It's a US cased watch and won't have a particular "model", simply a "Ladies" or "Gents" watch.

How long were Omega watches cased in the US? It didn't occur to me that it's an American case until just now. Are there a lot of US-cased Omegas around? I've only owned a dozen or so Omegas, and I don't recall seeing any that weren't "fab suisse".

From the 1920’s until the 1970’s at least. The U.S. models tended to be either 14K gold or gold filled, as these were not popular case metals in Europe.

It was also done to avoid heavy customs on 18K gold cases.

Ok, I went back through my photos and I found several of my Omegas, mostly women's models, were actually cased in the US.

If you live in the US then the chances of having US cased models (vintage) may be higher than Swiss cased.
Same as in the UK where locally cased watches were more prevalent (especially gold models).
