After posting the Duchess the other day I found this one from the same ad so I picked it up. I was really pleased when I got it to find it is in nice condition. I believe this is Doris, a very pretty little watch. The ad with the Duchess has it at $50 and I found an ad for $37.50 so there might have been a solid gold and a gold filled version. At least those price points seem to indicate that. This one is gold filled with 2 emeralds, one triangle on each end. The movement is a 17 jewel not a 15 jewel as the ad states.
The full ad is pretty cool The_Berkshire_Eagle_Thu__Nov_21__1929

That's a beauty, a nice addition to your collection. I agree,
1930 Doris she is.

Thank you Bob : ) These older models are really cool and I don't have very many so it is nice to add to them. Only my second with emeralds.
Doris gets my vote too.
Dandy watch Kathy- I like it
