Other Details

NOTES:  This model has been identified by "Duo Wind" printed on the dial as well as the crystal listing in G-S Catalog No. 52, which identifies this crystal as used by the Duo Wind model.   The ad below shows this case but with a dial that reads "Self Winding", rather than "Duo Wind".  The watch has been seen with either configuration.  As shown below, I also have a 1951 version of this model with "Self Winding" on the dial instead of "Duo Wind".
