Another fantastic solid gold ladies with the wingnut aka orchid design.
Indon't know if I know her right off hand.
14K solid white gold, 4 emeralds, 2 diamonds
Beautiful watch, and unknown.
For those interested, the movement is most likely a replacement. The probably year of the subject watch is 1929. This is based on the following observations for this type of wing lug models:
- in 1928, they were just signed with Patent date and 14K
- in 1929, “Bulova” was added to the signature as in the subject watch
- in 1930, the “rail track” on the bezel changed from crosses like on the subject watch to “two crosses + rectangle” rail track (let me look for a link)
Here's an Ad but no name, I have one too, except mine is with Sapphires & Diamonds.

Nice one Plains, sweet find. Alas, 1928 Bulova Unknown
