HANDS Original


G.C.T. watches were used for navigational purposes on military airplanes. These types of watches were typically ordered by the Royal Canadian Air Force and U.S. Army Corps from American watch manufacturers such as Hamilton, Elgin and Waltham. With increased demand due to World War II., Swiss companies like Longines and Agassiz supplied similar precision timepieces. The watches were normally fi tted with a black for ease of reading, and the silver dial versions are rather unusual. The movement?s eccentric regulator allows for extremely accurate timing.
