Other Details


NOTES:  This watch has been tentatively identified via G-S Crystal Catalog No. 60, which specifies this crystal as being used only by the Ambassador H.  The case on this watch is very similar, if not identical, to the earlier DuoWind.  There were several models of DuoWind, which bore that name on the dial, and later went by other model names, with the "DuoWind" on the dial replaced with "Self Winding". The former DuoWind model that was later called the Spencer is another example of this sequence of events.
