Jaeger-LeCoultre (JLC) is a luxury watch and clock manufacturer based in Le Sentier, Vaud, Switzerland. In 1833 Antoine LeCoultre (1803-1881) founded a small workshop, which was to become the Manufacture Jaeger-LeCoultre. In 1844, LeCoultre measured the micron for the first time; he created the world's most precise measuring instrument, the millionometer (a device capable of measuring to the nearest thousandths of a millimeter).
In 1847, LeCoultre created a revolutionary system that eliminated the need for keys to rewind and set watches. A push-piece activated a lever to change from one function to another. In 1851, at the first Universal Exhibition in London, LeCoultre was awarded a gold medal in recognition of his collective works in the fields of precision and mechanization.
Cartier, a client of Edmond Jaeger for several years signed an exclusive contract with the Parisian watchmaker in 1907 under which agreement Jaeger, LeCoultre & Cie crafted the stunning watch creations of
Cartier.
