The Jaeger-Le Coultre Master Compressor blends the classic look of Jaeger-LeCoultre (JLC) watches with multiple modern dial designs that take Swiss timekeeping to a new level of sophistication. Jaeger-Le Coultre Master Compressor watches are as handsome as a Swiss watch can get - often made from the finest materials including crocodile leather straps, pink gold, titanium, in addition to the standard stainless steel construction of many Swiss timepieces. The Jaeger Le-Coultre Master Compressor is offered in multiple case sizes, ranging from 41.5 millimeters up to 46 millimeters.

Jaeger-LeCoultre is based in Le Sentier (in Le Chenit), Vaud, Switzerland and was founded in 1833 by Antoine LeCoultre in his small workshop, which was to become the Manufacture Jaeger-LeCoultre. His son, Elie LeCoultre, understood that it in order to control quality, it was necessary to control the entire assembly of Jaeger LeCoultre watches. Within 30 years after founding, Jaeger-LeCoultre had created more than 350 calibers for a variety of chronographical and repeater functions.
