Here's another Sears ad that shows the Duo-Wind.  It's from the Spring-Summer catalog 1950.

The dial reads "Automatic".

Wow! a Second ad Dated 1950 confirming the 'DUO WIND' ID.

And a second ad from 1950 that does not match your watch. Your watch remains a closer match to the Thayer ad.

And you're welcome.

IMO Lisa You are placing too much emphasis on what an artist has rendered completely neglecting the Dates of the Vintage advertisements in the process.

The Watch was manufactured in 1950, not 1952.

I am perfectly aware that your watch was manufactured in 1950.  So what?   The date of the ad is of minor importance to the discussion.  What matters is what the ad shows and describes. 

Two 1950 ads do not match your watch.  Four 1952 illustrations do match your watch. 

The idea that we shouldn't rely on an ad dated two years after the subject watch is silly and wholly inconsistent with practice on this site.

* note: The reference to Dr Ranftts site provided previously by Members participating in this discussion indicating an initial production Date of 1955 for the Movement showing is erronious, the link provided references the Bulova 11AC, 11ACA and the  11ACC.

The Movement found in the subject Watch is in fact an 11 AAC.

a 1951 database ad shows a 'DUO-WIND' with DUO WIND on the Dial.

Although designated as the 'DUO WIND' "G" IMO the subject is not the "G" variant as the Dial and Hands differ.

From this information  I will conclude that in 1950 and in 1951 this design was named the 'DUO WIND' as its bi-directional Movement suggests and in 1952 then becomes the 'THAYER' equipped with an omni directional winding automatic Movement as in the current database examples and ads Dated 1952 and beyond.

That more than works for me.

1950-51 = Duo-Wind

1952+    = Thayer

Bulova may have thought that putting this cool new function (I know it technically wasn't a new function, but for Bulova it was) name on the dial was a good marketing ploy in 1950, but then as more selfwinding/auto models started to be manufactured they then decided to give it an actual name like the Thayer (anyone know where the name may have come from).

Duo-Wind  >> Selfwinding >> Automatic

Leave it to Bulova to confuse me.  June 1953 ad for a Duo-Wind "F".
