I have been hoping one of these would come up because I am drawn to the lovely angles in this and the Gloria model. I believe this is Betsy Ross from the 1948 ad attached below. It was listed as yellow gold but it actually ended up being pink gold which is my favorite so I am happy about that.
It has a 1948 date serial #849848, and BULOVA O 14K GOLD O on the back of the case. Inside is swirls and service marks. It has a 5AB 17 jewel working movement and matching pink gold signed crown. The dial and crystal have average wear.
