Hmmm. One screw on the winding wheel. When did Hamilton abandon the 2-screw winding wheels? Nice watch Jerry! (Good to see you last weekend too!) | ||||
Jerry, Thanks for sharing the nice 992. Would you care to share the movement s/n? It's not clear on my ageing monitor. Robert | ||||

Jerry, Thank you very much. Your movement was one of a thousand unit lot (1088001-1089000) that went to the "Finishing Dept." in two separate groups on 1/31/1914 and 2/7/1914, and probably was completed one to three months later. Peter, The conversion from the "2 screw" winding wheel to "1 screw" took place somewhere in between, 1062921 and Jerry's movement, 1088081. Keep in mind, there may have been some overlapping of the serial numbers during the transition period. Others may have this narrowed down more closely. Robert | ||||
