Founded by Florentine Ariosto Jones

IWC Schaffhausen was founded in 1868 by American engineer Florentine Ariosto Jones, who chose Schaffhausen for its water-powered machinery — making it the only major watch brand in German-speaking Switzerland. Now part of Richemont, IWC is known for its Portugieser, Pilot's Watch, and Aquatimer collections, and for producing large, technically accomplished complications.
