That's a variant of the gold-filled version of the Hamilton Case Model No. 12 (pendant shoulders).

It's an uncommon case and would be correct for a 992B circa 1942-1948. It would make a nice combination with a Signature Type 2 992B, which is what I have in my example.

The more common version of the Case 12 is base metal (chrome-plated brass), which I have never seen with pendant shoulders.


Here are Case 12 Examples w/o Shoulders

Thank you Edward mine 992b is from 1941/42
and here is the picture of it in salesman case now.

IMHO that movement would be fine in your case 12.

From the diamond crossbar hands I'm guessing it's a Signature Type 2.
