About IWC
The International Watch Company (IWC) has a rich history dating back to 1868 when American watchmaker Florentine Ariosto Jones founded the company in Schaffhausen, Switzerland. Jones aimed to combine advanced American manufacturing techniques with the skilled craftsmanship of Swiss watchmakers. Despite initial challenges, IWC quickly gained a reputation for producing high-quality pocket watches and, later, wristwatches.
Throughout the 20th century, IWC was a force of innovation and expand its repertoire accordingly. In the 1930s, they introduced their first pilot's watches, which would become an enduring part of their identity. During World War II, IWC produced these watches for both civilian and military use. The post-war period saw the introduction of iconic collections like the Ingenieur in 1955 and the Aquatimer in 1967. In the 1970s, IWC collaborated with Ferdinand A. Porsche to create the first watch with a built-in compass. The company's commitment to technical innovation and classic design has persisted into the 21st century, with IWC remaining a respected name in luxury watchmaking.
