The technical characteristics of its automatic calibre – including a titanium tourbillon carriage, high-inertia and high-frequency balance and an oscillating weight mounted on ceramic ball-bearings – enable it to achieve remarkable levels of performance. Entirely decorated by hand, it testifies to the mastery of rare crafts cultivated within the Grande Maison. Its refined aesthetics and exceptional finishes are a tribute paid by
Jaeger-LeCoultre to traditional fine watchmaking.
