Jaeger-LeCoultre brings craftsmanship, artistry and imagination to life. The first Jaeger-LeCoultre workshop was founded by Antoine LeCoultre in 1833, but it was over 30 years of collaboration between the LeCoultre family and French watchmaker Edmond Jaeger that led to the official launch of Jaeger-LeCoultre in 1937. Still based in Switzerland’s Vallée de Joux, the pioneering brand has gone on to design and develop over 1000 different movements and counts more than 400 registered patents to its name. From its founder’s invention of the Millionmetre – the most precise measuring tool of its time – in 1844, to the creation of the Calibre 101, which weighs just one gram and was worn by Queen Elizabeth II for her coronation, every element of a Jaeger-LeCoultre watch’s mechanism continues to be created entirely in-house.
