The Hamilton Watch Company increased its production of precision watches following the entry of the United States into the Second World War in. Its 16-size 992b railroad quality pocket watch formed the basis for their Watch, Master Navigational, most of which, 73,285, found their way into Air Force use, while 21,152 were assigned to the US Navy, with 312 going to the Royal Canadian Navy. The movement was designated 4992b. And 1969, with US Government marked bridge when production ceased, about 140,000 had been made.
While it retained the fine quality of the 992b, it differed from it in having a sweep second hand , a 24 hour dial reading GCT (Greenwich Civil Time which later will become Greenwich Mean Time) and a hacking function, allowing the movement to be stopped easily by pulling out the crown so that the time shown could be set precisely to GMT. This watch runs well, it has been cleaned and serviced keeps good time and is in excellent condition you can still see some of the military engraving on the back of the case it might have wore off or it was polished off some people did that?
