Good second ad Bobbee. It conflicts with the first ad in the root record, but based on the second ad above, it looks like the Duo Wind is a feature stated on the dial, and the model was indeed a Watertite. I was thinking the other way around based on ad in root record. Wonder how this impacts other records named Duo-Wind based on dial. I'm checking Duo-Wind ads now, and I gotta check the lugs on Thayer ads/records too, but I think Thayer was different and a later date :)
Digging a little further, the 1955 Model Price Lists show there's a model named "Watertite E" and one named "Watertite Duo Wind E". Both w/ same price and SAME unique internal Bulova model numbers.
Do the watches in the two ads above both show Duo Wind on the dials? It looks like the second ad graphic also has Duo Wind? The watches in the ads look the same. We only have a price for the second ad stating Watertite "E", but the price missing in the first ad would only come into play if it were not $55.
I'm back at unknown now, and we have confilcting ads.....although I'm thinking it's just not known which of the two models it is.
EDIT: Watertite Duo Wind "E" ad dated 1951. Watertite "E" ad dated 1950.
