IWC

Founded in 1868 by American watchmaker Florentine Ariosto Jones, International Watch Company (IWC) has established itself as a pillar of Swiss watchmaking excellence. Their Pilot's Watch collection, dating back to 1936, has set industry standards for aviation timepieces, with the Big Pilot becoming an icon of the genre. The Portugieser line, originally commissioned by Portuguese merchants seeking pocket-watch accuracy in a wristwatch, demonstrates their mastery of precision chronometry. The brand's innovative approach is evident in their perpetual calendar mechanism developed by Kurt Klaus, while their commitment to sustainability in luxury watchmaking sets new industry standards. Each collection, from the elegant Portofino to the robust Aquatimer, showcases their dedication to engineering excellence.
