A major player in watchmaking history since 1833, Jaeger-LeCoultre is the first Manufacture to have been established in the Vallee 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 the watchmaking development of the entire region. The Manufacture has an impressive range of world firsts, superlative creations and legendary models to its credit, including the Reverso, the Duoplan, the Master Control, the Memovox Polaris, the Gyrotourbillon and the Atmos. 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 178 years of expertise, calls for the exercise of no less than 40 professions and 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 1,231 calibres and 398 registered patents, Jaeger-LeCoultre remains the reference in high-end watchmaking.
