Hamilton has a great history in producing naval watches. Before World War I, Hamilton was one of the largest manufacturers of pocket watches. After WWI, production shifted towards wrist watches and during World War II, production of consumer watches was stopped completely. Hamilton was extremely successful in producing marine chronometers in large numbers to fill the needs of the United States Navy, and its allies. The current Khaki Navy collection consist of stylish re-interpretations of the nineteenfourties chronometers as well as well as nineteenfifties style and modern diving watches for the adventurous Hamilton fan.
