Reverso grande complication à triptyque
Displaying three dimensions of time on three faces, the Reverso grande complication à triptyque is a world first and a unique expression of the Manufacture's total mastery of both traditional finewatchmaking tradition and avant-garde technology. A few years ago Jaeger-LeCoultre set itself a challenge: to bring together civil, sidereal and perpetual time in the legendary reversible case. But the Reverso grande complication à triptyque's achievements go beyond this: its manually wound mechanical movement offers some unique subtleties of construction as well as extraordinary horological complications. On its front face, it has a tourbillon endowed with an ellipse isometer escapement, a masterpiece of design and execution whose transmission system does away with the traditional Swiss pallet. Inspired by marine escapements, it offers peerless precision. Its back face features a zodiacal calendar with an astronomical chart, an equation of time and sunrise and sunset times. The watch's third face is remarkable for its unique location: a perpetual calendar in the Reverso carriage. A highly original patented mechanism makes it possible to transmit energy from the movement to the carriage. In total, the timepiece boasts 18 complications, and has six patents pending.
