Founded in 1833 by Antoine LeCoultre in the Vallée de Joux, Switzerland, Jaeger-LeCoultre began as a modest watchmaking shop. From the outset, the Manufacture revolutionized watchmaking by uniting all crafts under one roof, driven by an obsession with accuracy that led to innovations such as the Millionomètre in 1844, the first instrument that measured to the micron (one-millionth of a meter). In 1903, LeCoultre partnered with Parison watchmaker Edmond Jager, forming what would become Jaeger-LeCoultre.
Often called “the watchmaker’s watchmaker,” Jaeger-LeCoultre earned this reputation by supplying movements to other leading houses, including Patek Philippe, Audemars Piguet, and Vacheron Constantin. With hundreds of inventions, over one thousand movements, and landmark achievements in ultra-thin engineering and mechanical complexity, the Manufacture has continually pushed the boundaries of what is possible. Rooted in the Vallée de Joux and defined by fully in-house mastery, Jaeger-LeCoultre embodies precision, creativity, and technical excellence at the highest level of watchmaking.
