Jaeger LeCoultre Q1666520 Master Grande Tradition Tourbillon Platinum Grey Dial

The Jaeger-LeCoultre Q1666520 Master Grande Tradition a Tourbillon represents a pinnacle of horological refinement from the storied Le Sentier manufacture, first introduced in 2011 as a limited edition of just 200 pieces. Crafted in solid platinum, this 43mm case houses the automatic Calibre JLC 978, notable for its impressive 48-hour power reserve and high-precision tourbillon escapement—a technical marvel and cornerstone of haute horlogerie.

The watch's complications, which include a tourbillon and date, are thoughtfully integrated without disrupting the dial’s classic symmetry. Water resistance up to 50 meters and a substantial alligator leather strap further underscore the robust yet elegant design philosophy. Collectors value this reference both for its exclusivity and for its central place in the evolution of the Master Grande Tradition series. The Q1666520 serves as an essential chapter in Jaeger-LeCoultre’s exploration of complex mechanisms, offering a blend of historical reverence and contemporary watchmaking prowess.
