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 a US space mission. In 1994 Fortis introduced strict endurance tests. This same year the Star City Training Center chose the Fortis Official Cosmonauts Chronograph as part of its issued equipment. Fortis automatic wristwatches have proven their space capability inside and outside of the protection of the space station. Since 1994 Fortis has been the exclusive supplier of manned space missions authorized by the Russian Federal Space Agency. In 1997 the same watch, the Fortis Official Cosmonauts Chronograph, became the official watch of the German-Russian space mission MIR 97.
