The Jaeger-LeCoultre Master Control collection, introduced in 1992, was created to house the brand's new generation of calibres under the industry's most stringent testing protocol. It was the first collection to undergo the "1000 Hours Control," a six-week examination of the fully cased watch that far exceeds standard chronometer certification.
This process assesses precision through six positions, temperature changes, and power reserve function to guarantee superlative reliability. This modern reference is powered by the in-house Calibre 899, a high-performance automatic movement featuring a solid 22-carat gold oscillating weight.
Since its founding in Switzerland's Vallée de Joux in 1833 by Antoine LeCoultre, Jaeger-LeCoultre has established itself as a true manufacture, bringing nearly every aspect of watchmaking under one roof. This comprehensive in-house capability has earned it the esteemed title of "the watchmaker's watchmaker," as it historically supplied movements to many other prestigious brands.
The brand's portfolio is defined by both profound technical mastery and iconic design. Jaeger-LeCoultre is responsible for horological milestones such as the Calibre 101, which remains the world's smallest mechanical movement, and the near-perpetual Atmos clock, powered by minute changes in ambient temperature. Perhaps its most recognizable creation is the Reverso, a watch born from the need for a durable timepiece for polo players in 1931, which features a unique swiveling case that has become a celebrated icon of Art Deco design.
