IWC Schaffhausen

IWC International Watch Co. AG, or IWC Schaffhausen, is a luxury Swiss watch manufacturer based in Switzerland. Founded by American watchmaker Florentine Ariosto Jones to combine Swiss craftsmanship with modern engineering technology from the U.S. to manufacture watch movements and other watch parts for the American market. The only watch manufacturers in north-eastern Switzerland at the time, The International Watch Company, previously known as the International Watch Chronology, was founded in Schaffhausen in 1868.

IWC established itself in 1893 with the invention of Calibre 52, later known as the Schaffhausen. It has specialized in the creation of complicated movement ever since reaching its peak with the pocket watch version of the Grande Complication. The "Probus Scafusia" stamp became the unrivaled mark of quality, prized by serious collectors.

During the quartz revolution, the brand continued to design complicated models such as the Da Vinci. It was also during this time that IWC pioneered new watchmaking technologies, notably the first titanium bracelets, developed in 1978. Then in 1990, Grande Complication was born, followed in 1993 by the IWC flagship model, the Schaffhouse Destrier, launched to marks its 120th Anniversary. This was succeeded by the Portugieser Uhr, a commemorative limited edition.

IWC has been a subsidiary of the Swiss Richemont Group since 2000.
