Switzerland · Founded 1868
IWC Schaffhausen
The psychiatrist Carl Gustav Jung was a co-owner of IWC until 1929.
IWC Schaffhausen was founded by an American, Florentine Ariosto Jones, in 1868 in Schaffhausen, far from the Jura watchmaking centres, and has belonged to Richemont since 2000. It is known for pilot's watches, the Portugieser, the Ingenieur, perpetual calendars by Kurt Klaus and early titanium and ceramic cases. Most new watches list between about €5,000 and €15,000.
History
Florentine Ariosto Jones, an American watchmaker who had been a director of E. Howard & Co. in Boston, founded the International Watch Company in 1868 to combine Swiss labour with American machinery for the US market. Rebuffed in French-speaking Switzerland, he found support in Schaffhausen from industrialist Heinrich Moser, whose hydroelectric plant on the Rhine could power a factory. Jones rented space from Moser in 1869, and a purpose-built factory by the river was completed in 1875. Tariffs, financing and machinery problems followed, and Jones returned to America that year.
Johann Rauschenbach-Vogel, a Schaffhausen machine manufacturer and shareholder, bought the company in 1880, and his family owned it for four generations. From 1884 IWC made Pallweber pocket watches with digital hour and minute displays, and in 1899 it sold its first wristwatches. After 1905 the firm belonged to Rauschenbach's heirs, whose husbands included Ernst Jakob Homberger and the psychiatrist Carl Gustav Jung. Homberger bought Jung's share in 1929 and became sole owner. The Special Pilot's Watch followed in 1936, the Portugieser in 1939 and the Big Pilot's Watch in 1940.
In the Second World War IWC supplied observation watches to the German Luftwaffe as well as watches to the British War Office. The Mark 11 of 1948, built for British military service, protected its calibre 89 with a soft-iron inner cage against magnetism. Albert Pellaton's pawl-based automatic winding appeared in 1950, the Ingenieur in 1955 and the Aquatimer in 1967. VDO Adolf Schindling took a majority stake in 1978. Under Günter Blümlein, IWC made titanium watches with Porsche Design from 1980 and launched Kurt Klaus's Da Vinci perpetual calendar in 1985.
In 1991 Blümlein placed IWC, Jaeger-LeCoultre and A. Lange & Söhne in the LMH holding, which Richemont bought in 2000 for CHF 2.8 billion. The seven-day Calibre 5000 appeared that year, the 46 mm Big Pilot's Watch returned in 2002 and the in-house 52000 calibre family followed in 2015. In 2018, its 150th year, IWC opened a Manufakturzentrum that brought movement and case production together. The Portugieser Eternal Calendar, a secular perpetual calendar, won the Aiguille d'Or at the 2024 Grand Prix d'Horlogerie de Genève.

Questions
- Who owns IWC Schaffhausen?
- Richemont, since 2000, when it bought the LMH group that also held Jaeger-LeCoultre and A. Lange & Söhne. Before that IWC belonged to VDO Adolf Schindling from 1978 and, from 1880, to the Rauschenbach and Homberger family.
- What does IWC stand for?
- International Watch Company. The American founder Florentine Ariosto Jones chose the name in 1868 because he planned to sell watches made in Switzerland to the United States.
- Where are IWC watches made?
- In Schaffhausen, in German-speaking northern Switzerland. The headquarters has stood on the Rhine since 1875, and a manufacturing centre opened in 2018 combines movement and case production.
- Does IWC make in-house movements?
- Yes, for much of the range. IWC manufactures calibre families such as the 52000, 82000, 69000 and 32000. Some entry models use the calibre 35111, based on a Sellita movement that IWC modifies.
