Its Jubilee collection, which CEO Jérôme Lambert says reflects the brand's key value of mechanical elegance, features three exceptional pieces - Master Grande Tradition Gyrotourbillon 3 Jubilee, Master Ultra Thin Jubilee and Master Grande Tradition Tourbillon Cylindrique à Quantième Perpétuel Jubilee.
As the watchmaker's 10th grand complication in the Hybris Mechanica series, Master Grande Tradition Gyrotourbillon 3, limited to 75 pieces, brings to light the best of the house's technical innovation and craftsmanship.
The novelty, a first chronograph equipped with a flying tourbillon, is a masterpiece in precision timing thanks to its spherical gyrotourbillon, which compensates for positional errors with its synchronised double rotation and a spherical-shaped balance-spring fitted with two terminal curves with a 14ct blued gold balance.
Inside its 43.5mm extra-white platinum case beats a Calibre 176, the latest mechanical heart researched and developed by Jaeger-LeCoultre engineers. The 592-part, manually wound movement features complications, including an instantaneous digital-display chronograph activated by a single push-piece and day-night and 24-hour indication on the three independent dials. The grand complication has a power reserve of 48 hours.
Its ultra-white platinum case is an innovation to substitute copper residues in the material to create an additional white and bright finish. Artisans have revived an ancient technique in which its main plate has been manually hammered, while its white gold folding clasp incorporates an additional mechanism to make it more adjustable and comfortable.
Jaeger-LeCoultre was one of the first master artisans to develop ultra-thin calibres for wristwatches, ensuring the Master Ultra Thin is close to the heart of the brand's spirit. The timepiece, powered by the manual-winding Calibre 849 housed inside an extra-white platinum case 39mm in diameter and 4.05mm thick, comes in a limited 880-piece series.
