1951 watch - Could be a Duo-Wind "F"; 1951 Ad and 1952 Ad. Not finding a Thayer ad before 1952.

I'm not finding a Thayer ad from 1952.

1955 Thayer ad does show similar dial w/ wording selfwinding (vs Duo Wind on two ads linked above).  Here's a 1953 Thayer ad w/ selfwinding on the dial.

1950 Duo WInd "F" ad w/ a couple variants of this case (mounts appear to be the difference). Another 1950 Duo Wind "F" ad, but I can't make out wording on bottome of dial. 

All Duo Wind ads linked by Andersok and the others I've found so far say Duo Wind (or nothing) on dial vs selfwinding as in subject watch (and the 1953/55 Thayer ads).

Case also similar to December 1951 Ashford ad.

Three 1952 Thayer records in watch database.  All say selfwinding on dial (vs Duo Wind).  Geoff's 1952 example has Thayer hangtag, and a clamshell case saying "self winding".  
Wondering if there was some wiggle room on when Duo Wind ended and Thayer began? 
Also wondering with so many 1953 ads showing selfwinding on the dial of Thayer and earlier Duo Wind ads showing Duo Wind on the dial....
I did find a Thayer ad dated 1952, but its a postcard I think.

EDIT: I just found a 1952 Thayer ad with Duo Wind on the dial from this watch record.... and Plains 1951 Duo Wind watch record w/ selfwinding on the dial.  This shoots down my thinking above.

I would call this beauty a Duo Wind F based on what we have. Interestingly, my Thayer (linked above) came in a  box with Duo Wind documentation. I always wondered if it belonged, now I tend to think it does.

I agree. I think your watch did come with the documentation. Kind of a subset of Duo Wind, at last at the watch function level anyway.  
I was hoping for a clean break in years of advertising btwn Duo Wind and Thayer, including wording appearing on the dials, but that didn't pan out based on ads and "selfwinding" printed dials.  Cross over btwn ads and years.

I now agree w/ the duo wind ID vs Thayer, and think the break is btwn 1951-52 with some possible overlap.
