All-original 16-size 21-jewel 1st-model Hamilton 992

Hamilton's 16-size 21-jewel 992 debuted in 1903 with a pattern identical to the older and larger 18-size 940, which eventually became known as the First Model, even though there were two mechanical variants within the run that should have qualified as model changes but didn't. The Second Model appeared a decade later with the very same design but with pinstripes, which was entirely cosmetic, so it shouldn't have qualified as a separate model but did. The two variants within the first model were the number of dial feet, which went down from four to three, and the change from the two-screw crown boss to a single larger LHT one. This beautiful and original example is the earliest of all the variants and was just restored for the next owner with all twenty-one jewels still intact and all hardware present and correct, still in its original 25-year gold-filled Crescent clamshell case. The dial is the correct double-sunk light Arabic and is flawless behind blued moon hands and a new beveled glass crystal. Matching lanyard and display stand included.
