One of the early selfwinding DuoWind; date code is located on the rotor ; SS case ; note the US Pattern marked on the movement dial side ; 17 jewels breguet hairspring ; no anti-shock
I can't really understand why it is a "challenge", Mark. You say we see the watches called the Duo Wind, then Spencer and Duo Wind then Thayer.
This watch is none of the above, it's movement is a Duo Wind, and the watch is clearly a Watertite, or a Watertite Duo Wind, not a Duo Wind. As you named it.

This one was kinda challanging to think through, for me anyway. Had to go to model list for name confirmation. Determine then apply dates of ads, and think through the things we've discussed. Rule out one ad as a possible "mistake" etc... But it was a fun one, and helps me learn more about this series.

Like OT says, don't the duo-winds all have snap on backs?
What is this about? Familiar Duo-Wind "G" with the easily recognisable lugs, then below it mentions the Watertite "E" as being similar?
EDIT:- 1952 ad. I say we put the name exactly as it says on the nearest dated ad, and walk away!
Thank you Bobbee. That is my watch from the lugs down to the dial and hands mentioned at the bottom of the ad. Not luminous.
I did notice the change in the cases from the lugs on the subject watch to the lugs on my watch (duo wind F). How common is it to find an ad for a watch two years after the mfg date on the case and watch which both match and say 1950?
See Will, this is the confusion I mentioned and the rest shall follow.
