The Inventors of the Valle de Joux.

A leading player in watchmaking history since 1833, Jaeger-LeCoultre is celebrating its 180th anniversary. At a time when the Swiss horological industry was still built around home-based workshops, Antoine LeCoultre and his son Elie decided to unite under one roof the many forms of expertise involved in making a watch. LeCoultre & Cie thus become the first Manufacture of the Valle de Joux. It now houses the over 180 skills required to develop and produce the most prestigious timepieces.
