LeJour was a name used by the French maker Yema for its U.S. export watches. The Flygraf was an aviator’s chronograph featuring a uniquely styled dashboard dial with blue and silver slide rule bezel. The present example is extremely rare with the famed Valjoux 726 movement. The movement and caseback are signed JP Pingouin, Yema’s parent company.
