In 2013, Jaeger-LeCoultre celebrates its 180th anniversary and presents the Master Grande Tradition Gyrotourbilon 3, the tenth work in the Hybris Mechanica series dedicated to the Grande Complication models from the Manufacture.
The spherical tourbillon immediately catches the eye at first glimpse of the face of this Master Grande Tradition Gyrotourbillon 3 Jubilee model. Nonetheless, even for certain devotees of horological innovation who have already attempted to probe the secrets of the first two spherical tourbillons developed by the Manufacture, this mechanism appears in an entirely new light: for the very first time, the absence of an upper bridge invites the gaze to wander freely through this entrancing miniature universe.
It is composed of two carriages, respectively rotating in one minute and 24 seconds (meaning 2.5 times a minute) and does not owe its existence exclusively to the inventiveness of the engineers and watchmakers of the Manufacture, but also to the use of cutting-edge equipment such as the five-axis machining centre. It is impressive to think about the fact that such a complex ensemble of around one hundred parts weighs less than one gram.
The latest of the 1,242 calibres built by the Grande Maison in the Vallée de Joux is named Calibre 176. Developed, crafted and assembled in the Grande Complication workshops of the Manufacture, it combines the gyrotoubillon with a chronograph function.
Jaeger-LeCoultre has developed an instantaneous digital-display chronograph boasting extraordinary precision that destine it to become a new watchmaking legend, since it is the first chronograph to be associated with a flying spherical tourbillon.
It is also worth noting that the chronograph function of the Master Grande Tradition Gyrotourbillon 3 Jubilee is of the single push-piece type, an historical feature reflecting that characteristic of late 19th century models.
The hours and minutes dial is characterised by its traditional opaline silvered decoration. It is swept over by new Dauphine-type hands entirely in harmony with the other features of this timepiece. Meanwhile, the chronograph display has a sunray rhodium-plated finish endowed with a classic aesthetic entirely dedicated to ensuring immediate readability; while the dial displaying the day/night indication features a hand-punched background and the night section has been coated with a translucent blue lacquer.
The Master Grande Tradition Gyrotourbillon 3 Jubilee comes in a new extra-white platinum case measuring 43.5 millimetres in diameter and 15.5 millimetres thick. The superbly elegant bezel and lugs are adorned with a polished finish creating a delicate contrast with the satin-brushed case sides.
The Master Grande Tradition Gyrotourbillon 3 Jubilee is fitted with a white gold folding clasp comprising a device enabling millimetre-accurate length adjustment according to the temperature and the humidity rate in order to guarantee a perfectly comfortable fit in all circumstances.
This model in the “Tribute to Antoine LeCoultre” Jubilee collection will be produced in a limited edition of 75.
