Exceptional Hamilton Master Navigation Grade 4992B with Hackable Sweep Second Hand

Like many American watch companies, Hamilton provided timepieces for the U.S. armed services in the time of war. This Hamilton G.C.T. military pocket watch was produced around 1941, at the very beginning of World War II. [The G.C.T. designation stands for Greenwich Civil Time, used by the U.S. military from 1924 to 1952, when they adopted the term Greenwich Mean Time.] The Hamilton G.C.T. is all present and correct: black dial, 24-hour indices, stem set hackable sweep second hand (stops for group synchronization), nickel finish movement. It's one of a production run of thirty-thousand pieces – the majority of which have not survived to present day. The coin-edged case, dial, hands and movement are in exceptional condition. Perhaps never issued or carried in the field. The 22 jewel engine is a perfect example of form following function – beautifully. A rare find. A delight forever.
