Railroad Grade
During World War II, production of consumer watches was stopped, with all watches manufactured being shipped to troops. More than one million watches were sent overseas. The company was extremely successful in producing marine chronometers and deck watches in large numbers to fill the needs of the United States Navy, and other Allied navies as well. The Model 21 Hamilton was built first and had a chain drive fusee and then followed by the Model 22, this model had a traditional main spring this was in a traditional double box and in a deck watch. The Model 21 & 22 had a two day power reserve and the movements of both were marked U.S. Navy Bureau of Ships. The model 22 was also used by the U.S. Army and on the back of some it is marked U.S. Army, but all the model 22 movements are marked U.S. Navy Bureau of Ships. The Model 23 was a 16 size pocket watch case with a black dial, but this was a stop watch.
