Nice watch was one of 4 running ladies watch freebie "throw ins" with a Men's Bulova I purchased. 3 of the 4 were Bulovas. Case is yellow plate, while lug assemblies are white with a single diamond on either end. Band might be original, as it is yellow gold with the diamond shape on each link is white and matches the shape of the indices and hands. I gave it a preliminary cleaning. It's still pretty cruddy in the cracks and crevices, but in excellent physical condition.
I don't find another like it in the database. Runs and keeps time.
Looks like you have the Gaiety 'B'
1961 LB147

Good ad find, Ken. I went through the linebooks from 1961 to 1966 and apparently missed this one. Guess I didn't enlarge the photos enough.
1960 Gaiety "B" works for me.
1960 Bulova Gaiety "B" looks like a good match.
