Dear TexasLady, your watch is the Catherine. We only have newspaper ads for this watch.
Alex I went though the partial ads for the 20s and 30s twice and must be missing the ad. Would you be able to post it here if you know where it is please? : ) I know this is your specialty and I am still learning, thanks.
I got the ID from the Watchophilia website.
Thank you Alex. Catherine it is. I can see the shield on the movement for 1931. Ad from Watchophilia from a 1931 newspaper ad.
1931 Bulova Catherine
1931 Catherine it is.
