Jaeger-LeCoultre is known not only for building luxury watches, but also for producing the corresponding movements. The quality of these movements is so well regarded, that are also supplied to some of the most famous Swiss watch brands, such as IWC, Vacheron Constantin, Patek Philippe, and Audemars Piguet.
The ‘Reverso’, introduced in 1931, is the most important model for Jaeger-leCoultre, amounting today to approximately 40% of total production, with many variations introduced.
A very interesting addition is the Master Compressor series. These exclusive sport/diving watches are equipped with a compressor key system, invented by Jaeger LeCoultre as an alternative to the conventional screw-in crown.
