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 existence. 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.
