The quest for perfection has always been linked to ideals of functionality at Jaeger-LeCoultre. Sheer technical innovation is of little value when not relevant to everyday life. Hence why these considerations have impacted the design of the Master Tourbillon.

In a true expression of ‘haute horology', Jaeger-LeCoultre produced the first classic Master Control to be fitted with a tourbillon regulator. The magnificent timepiece, dressed in the Master Control's classic lines and characteristically subtle design, returns the tourbillon to its original function - ensuring that the watch movement operates with ultimate precision.

Manufactured to be uncompromisingly precise and reliable, the Master Control tourbillon regulator bears all the creative hallmarks of the house of Jaeger-LeCoultre.
