Fortis is a Swiss watch manufacturer known for its rugged, purpose-built tool watches engineered for aviation, diving, and space exploration. Established in 1912, Fortis has a long-standing reputation for producing reliable timepieces with clear legibility, robust construction, and functional design. The brand made history as one of the first to mass-produce automatic wristwatches and later became internationally recognized for its space-tested watches, officially worn by Russian cosmonauts aboard missions to the Mir Space Station and the International Space Station. Built to perform under extreme conditions, Fortis watches emphasize practicality, precision, and endurance—values that have earned them a loyal following among pilots, divers, and explorers. From the utilitarian Flieger collection to the technically advanced Cosmonauts and Stratoliner series, Fortis continues to innovate while staying true to its no-nonsense, mission-ready DNA. Each Fortis timepiece is a testament to Swiss engineering tailored for the skies, seas, and beyond.
