Hamilton Pocket Watch – Military Issued G.C.T. Grade 4992B

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 1944, 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 to1952, 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 is gently worn (battle-tested?), but the dial, hands and movement are immaculate. The 22 jewel engine is a perfect example of form following function – beautifully. A rare find. A delight forever.

All our treasured timepieces are completely disassembled, expertly cleaned and oiled using the finest quality watch oil and gear grease, and adjusted for accuracy. Full one year warranty.
