Part of the Richemont group's Haute Horlogerie division, Jaeger Le Coultre is a fully fledged Manufacture, whose in-house movements grace not only their own prestigious timepieces, but often lend their prestige to other high-end brands. Antoine LeCoultre founded the brand in 1833 but it was not until 1866 that his son would transform the workshop into a manufacture. Paris watchmaker Edmond Jaeger did not join his name to the company until 1903. He brought with him ultra-thin movement calibers as well as a prestigious customer for the movements, Cartier. Today, the company is well known for a number of achievements, including the Reverso, the Memovox automatic alarm watch and the Atmos clock.
