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.

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.
