A major player in watchmaking history since 1833, Jaeger-LeCoultre is the first Manufacture to have been established in the Vallée de Joux, Switzerland. It played a pioneering role by uniting the full range of technical and artistic professions under one roof and made an indelible imprint on watchmaking development by developing legendary watches such as the Reverso, the Duoplan, the Master Control, Geophysic, the Memovox Polaris, the Gyrotourbillon, as well as the Atmos clock. Guided by time-honored know-how and a constant quest for technical enhancements, the master-watchmakers, engineers and technicians craft each watch in harmony with the same passion. Each masterpiece, heir to more than180 years of expertise, benefits from cutting-edge technologies while being crafted in harmony with the noblest traditions of the Vallée de Joux. Building on a vast heritage encompassing 1,242 calibres and 398 registered patents, Jaeger-LeCoultre remains the reference in high-end watchmaking.
