About Jaeger-LeCoultre
Antoine LeCoultre established his watchmaking workshop in 1833. LeCoultre was a horological inventor, having developed the pinion cutting machine, and a measuring device accurate to one micron. In 1903, a watchmaker named Edmond Jaeger challenged the Swiss manufactures to mass-produce an ultra-thin movement that he had invented. LeCoultre accepted and completed the challenge. This led to a partnership between the two watchmakers, laying the foundation for the company known today as Jaeger-LeCoultre. Jaeger-LeCoultre is part of the Richemont group.
