This is one of two Bulova watches that I purchased at an auction. The watch is running and appears to keep good time. I was planning to sell the watch, that is until my wife saw it lol.
Alex, I'll have another look at the advert as I think that it's part of my collection. However I suspect you are correct, which is worrying for a nation wide publication to get it wrong.
Here is another 1925 December newspaper clipping showing it as the Prudence.

Looks like in 1927 it was rebadged as 'The Ruth Elder'

In reply to Alex, I'll have another look by mybulova_admin
There's another ad with a 'Judith' in 1926 which looks nothing like the one in 1925.
I'm going with Prudence.
Prudence for me as well.
Well, guess I better get in line for Prudence, Well done Alex.
metwxman - nice watch. I have, on occasion had the same problem at my house, the one were my dear wife suddenly fancies one of my watches. Thanks for sharing this one.
