classical shape, fine materials, and extensive range of horological specialities, the Master Control timepieces have long been a favorite of those entranced by exceptional watchmaking. The range of models within the Jaeger-LeCoultre Master Control watch collection comprise a breadth of complications, from such practical offerings as a power-reserve indicator or dual-time display, to the most prestigious realms of the watchmaker's art--the perpetual calendar, the tourbillon, and the minute repeater. All of the mechanical movements that animate the Master Control timepieces are designed and crafted by Jaeger-LeCoultre and demonstrate the trademark technical innovation and aesthetic refinement of the brand; in addition, the movements found in the Master Control watch collection are distinguished by passing a gruelling in-house test program which lasts 1000 hours in total, ensuring both exemplary mechanical function, and precision.
