I've searched the data base and the closest I can come is in the second page of the adverts' slide #10 but I can't make it out well enough to tell. It has a hinged case that say's Pat. Jan. 11 1927, Bulova 14K Gold Filled, New York. Case measures 26.75mmx26.75mm. The 9AT movement has a dust cover.
Looks like a Ladies Sports model called "Wimbledon"

I saw that one but didn't think that the side engraving was the same. The top and bottom engraving do look the same.
Dennis - I like it,
Stephen, I'm not sure I see a Wimbledon here though, I think the sides are different.....
Agree, the engraving on the verticals looks different.

Wow you are good, This is what I think I see on the second page of 1928 Adverts' #10, and it looks like it say's Senator.
Thanks Fifth

However after looking at your advert again I see that the sub second hand box doesn't go up on the dial as far as the one on my watch?
Subject Watch has most likely had its Dial refinished.
Matches on all other points.

I will check the dial, do they always mark them on a refinish?
