The International Watch Company was established in 1868 by Florentine Ariosto Jones, an American engineer and watchmaker, in Schaffhausen, Switzerland, with the assistance of manufacturer and industrialist Johann Heinrich Moser. Its location in Schaffhausen makes the IWC the only major Swiss watchmaker to set up shop in eastern Switzerland.
Their Ingenieur model of watches -- a design based on the classic IWC Pilot Watch, a line made for the British Royal Air Force in the 1940s -- are specifically designed to counter the effects of external magnetic fields, making them ideal for pilots. The company's Portuguese line is designed for the avid boater; the Da Vinci family of watches pays tribute to the Renaissance inventor; the classic lines of the Portofino line recall Hollywood of the 1950s and movie stars' love for the Italian fishing village; and the IWC's Aquatimer series, along with their support of the Charles Darwin Foundation's preservation efforts, shows the company's history and respect for the diving community.
