Jaeger-LeCoultre Master Calendar Meteorite Dial Moonphase Q1558421

The Master Calendar Q1558421 marries celestial artistry with Swiss horological sophistication. At its heart, a rare and mesmerizing meteorite dial graces a 39 mm stainless steel case—each dial presenting a singular Widmanstätten pattern that evokes the vastness of space with delicate, natural geometries. The harmonious layout showcases a full calendar, with subtleties like twin apertures for day and month at 12 o'clock, a gracefully arc-shaped date ring indicated by a slender pointer hand, and a combined small-seconds and moon-phase subdial at 6 o'clock.

Powered by JLC’s in-house Calibre 866—an automatic movement delivering approximately 43 hours of power reserve—this timepiece ensures accuracy and reliability behind its sapphire-crystal case-back. Completing the package is a refined leather strap, elegant dauphine hands, and a polished bezel, all while preserving a water resistance up to 50 meters—blending everyday wearability with artisanal elegance and technical finesse.

History of Jaeger-LeCoultre

Jaeger-LeCoultre, founded in 1833 in Switzerland's Vallée de Joux, began as a small workshop established by Antoine LeCoultre. Driven by innovation and precision, LeCoultre's company quickly gained recognition for its high-quality timepieces and movement production. In 1903, a partnership with Parisian businessman Edmond Jaeger led to the formation of Jaeger-LeCoultre, combining Swiss watchmaking expertise with French elegance.

Throughout the 20th century, Jaeger-LeCoultre solidified its position as a leader in watchmaking innovation. The company's milestones include the creation of the world's thinnest pocket watch (1925), the self-winding Atmos clock (1928), the iconic Reverso watch (1931), and the Master Memovox alarm wristwatch (1950). Today, Jaeger-LeCoultre continues to operate as a true "Manufacture," designing and producing its timepieces entirely in-house, while maintaining its legacy of innovation and exceptional craftsmanship.
