Master Navigational GCT Watch MS28076-1 4992B 24 Hour and Carrying Case
This is an authentic US Military GCT (Greenwich Civil Time) Master Navigational Watch MS28076-1 (Post WWII), Hamilton Part No 33106, Grade 4992B 22 jewel movement, suspended within an original WWII-era metal Carrying Case. Watch serial number is 27125.
The watch rests suspended on shock-springs within the carrying case, and can be viewed through a glass window by rotating the metal door to reveal the watch. The metal case was also intended to shield the watch from possible magnetization set up by stray electrical currents within the airplane.
The watch winds but runs intermittently, thus requires service by a qualified watchmaker. The watch crystal has a slight crack along the edge between 35-40 min position, see photo.
