A benchmark in fine watchmaking, Jaeger-LeCoultre has produced several icons such as the Reverso, the Duoplan and the Polaris. With its numerous collections, the Sentier factory is one of the major players in the history of watchmaking, particularly when it created the world's finest mechanical watch with complications in 1907.

Since its creation in 1833, the "Grande Maison de la Vallée de Joux" has produced more than 1,242 different calibers and registered about 400 patents.
