For pilots, who spend their lives above the clouds, the equipment for their everyday flying life must be useful and easily readable. The worldwide use of squadron watches, in civil and military aviation and by pilots of aerobatic formation teams, is a proof that the FORTIS watches fulfill their exacting criteria. Good legability, robustness, user friendliness, functionality and water resistance have led to the award, in 2004, of "European Aviation watch of the Year" for the Fortis Flieger and Pilot models.
