Carrying Case for Master Navigational GCT Watch AN-5740
This is an authentic WWII-era Carrying Case made specifically to protect the Master Navigational GCT Watch used by navigators of aircraft such as bombers and transports of the US Army Air Corps and US Army Air Force. (Watch is not included).
The primary purpose of the Carrying Case was to protect the Master Navigational GCT (Greenwich Civil Time) Watch, whose accuracy was critical during aircraft navigation. The case opens by gently lifting the retaining band from the small retaining peg, and turning the top counter-clockwise. The watch is installed and 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 case is in good condition given its age. Measures 4 inches diameter and 2 inches deep. If you own a GCT stopwatch, this is an essential companion piece.
