History & Legacy of IWC Founded in 1868 by American watchmaker Florentine Ariosto Jones, IWC was built around a simple but ambitious idea: bringing together American industrial efficiency and traditional Swiss craftsmanship. Over the years, IWC earned a strong reputation for producing precise, purpose-built tool watches — especially pilot’s watches. One of the brand’s most historic contributions came during the 1940s, when IWC produced the legendary oversized “B-Uhr” navigation watches, now considered some of the most iconic military aviation timepieces ever made.
