Master Grande Tradition Tourbillon à Quantième Perpétuel is a luxury wristwatch by Jaeger-LeCoultre introduced in 2009.

Tourbillon model in the series Master Control, which, rare for this type of complication, is driven by a self-winding movement. Like all pieces of the Master Control series, it must also subject to the infamous 1,000 Hours test before delivery. In addition to the already extremely complex model Master Tourbillon the watch has the additional complication of a perpetual calendar.

The technical characteristics of the automatic calibre: titanium tourbillon cage, balance with variable inertia and high frequency, weight segment on ceramic ball bearings. The completely manually decorated movement affirms the perfect mastery of rare crafts that are exercised in the manufacture. The refined aesthetics and the unique elaborations are a tribute by Jaeger-LeCoultre to the traditional high watchmaking art.
