The Basics
This exceptional new model was inspired by the pocket-watch launched by Jaeger-LeCoultre in 1907, and which to this day remains the thinnest manually-wound mechanical pocket-watch in the world. Thanks to its “knife-shaped” case, which is only 4.05mm thick, it is the flattest manually-winding mechanical wristwatch in the Jaeger-LeCoultre collection. A perfect combination of simplicity and elegance, this timepiece is an ardent tribute to Jaeger-LeCoultre’s pioneering role in developing the category of ultra-thin watches. Unlike other versions, the Boutique Edition features a set of ‘feuille’ hands.

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.
