Notes

G.C.T. watches were used for navigational purposes. in original advertising literature they are promoted for use by aviators, explorers and scientists because of their accuracy. naturally they were also used by the military. american watch manufacturers such as Hamilton, elgin and Waltham also made similar watches. the watches were normally fitted with a black dial for ease of reading. the movement?s eccentric regulator allows for extremely accurate timing.
