The Jaeger LeCoultre watch company was built upon principles of innovation. In 1903, Parisian watchmaker Edward Jaeger sought to establish a manufacturing relationship with a Swiss company to produce the ultra thin calibers he had invented. Antoine's grandson, Jacques-David LeCoultre, agreed to the collaboration. This resulted in a collection of thin, luxury pocket watches promptly purchased by Cartier, along with an agreement that the movements would be produced exclusively for the Cartier jewelry company for fifteen years. Thus, the Jaeger-LeCoultre company was born, a relationship that has resulted in over 1,000 different calibers, hundreds of inventions and some of the most prized, luxury watches in history.
