Rather large ladies for 1931 I think. Probably the most etched/scrolled case I've seen for a Bulova ladies watch.
The dial is really cool with metallic designs. Sapphire type crown. I'm assuming 14k plate but I don't know.
A pretty wild 16 Jewel, 10 A movement.
I don't know this watch and will look in the ads but it's pretty usual.
