Fortis was founded by Walter Vogt in 1912. Twelve years after its establishment, Vogt set up production with John Harwood, inventor of the automatic wristwatch. In 1926, Fortis released the patented Harwood Automatic, the first self-winding wristwatch at Baselword. By 1943 Fortis was introducing the world’s first waterproof watches with the Fortissimo models, which were increasingly popular. In 1962 the Spacematic Automatic was constructed to hold up in extreme conditions and temperature changes. The watch was tested by the seven members of an US space mission. Since 1994 Fortis has been the exclusive supplier of manned space missions authorized by the Russian Federal Space Agency. It have also supplied watches to many worldwide military squadrons such as the : Jagdgeschwader (Germany), Swiss 11 Fighters (Switzerland), Hellenic Tigers (Greece), NATO Forces (Hungary), Immelmann 51 (Germany), Thunder Tiger Aerobatic Team (Taiwan) and Papa Squadron (Hungary).
