Walter Vogt founded Fortis in 1912 in Grenchen, Switzerland, as a wristwatch manufacturer. Through the 1910s and 1920s Fortis built a reputation for robust Swiss mechanical watches for the German and Central European markets. Its major technical contribution came in 1926: Vogt commissioned British watchmaker John Harwood to industrialise Harwood's 1922 self-winding mechanism, and Fortis produced the world's first serial automatic wristwatch, the Harwood 1926. Approximately 30,000 Harwood automatics were produced by Fortis through the early 1930s before the model was discontinued.
The brand's modern identity was forged by aviation and space. Fortis produced pilot watches for the German Luftwaffe through the 1930s, the Swiss Army through the 1960s, and then, in a 1990s alliance that defined the brand, became the official supplier to the Russian Federal Space Agency (Roscosmos). The partnership was established in 1994; Fortis was tested against the rigorous specifications of orbital spaceflight (shock, vibration, vacuum, temperature extremes, radiation) and approved for Russian cosmonaut use.
Every subsequent Soyuz mission, including the long-duration ISS expeditions from 2000 onward, has included a Fortis Cosmonaut Chronograph on the wrist of at least one crew member. Specific references: the Official Cosmonauts Chronograph (matte steel, Valjoux 7750-based chronograph, 42mm), the B-42 Official Cosmonauts Chronograph (titanium for weight savings), and the Spaceleader. Fortis references have been worn on approximately 100 manned missions in total, more than any other watch brand to date, including the first Russian ISS mission in 2000.
Fortis remains independently owned. In 2018, German entrepreneur Jupp Philipp acquired the brand from its previous owners and recapitalised the operation. Under Philipp, Fortis has reaffirmed its independent status, continued the Roscosmos partnership, and expanded into the Flieger pilot-watch line (a classical Luftwaffe-style revival) alongside the space references. Retail runs from approximately CHF 2,500 (Flieger three-hander) to CHF 5,000 (Cosmonauts Chronograph) and CHF 10,000+ for limited-edition mission-specific commemoratives. The brand produces approximately 8,000 watches per year and remains Swiss Made throughout.
