defy classic zero-g

Trouver le système qui sera à la montre bracelet ce que fut le Tourbillon aux montres de poche est un des grands défis de ce XXIème siècle.
Véritable révolution technique, la manufacture Zenith a imaginé le système Zero-G, autrement dit zéro gravité !
Son Tourbillon à cage gyroscopique comprend un échappement monté sur cardans à l’image des chronomètres de marine. L’organe, sensible aux variations des positions, est maintenu en position horizontale constante, garantissant une amplitude optimale au balancier-spiral. La coordination est assurée par une invention brevetée Zenith : un deuxième train d’engrenage sert de référence au basculement des axes de l’échappement et un engrenage différentiel à inverseur compense tous les mouvements relatifs des bâtis.
Le Tourbillon Zero-G, dont la cage totalise à elle seule 166 composants, 10 roues à engrenages coniques à dentures spiroïdales et 6 roulements à bille, a été développé sur la base du calibre automatique El Primero

defy Xtreme zero-g

In a veritable technical revolution, ZENITH Manufacture has devised the Zero-G system, in other words zero gravity! The gyroscope cage Tourbillon comprises an escapement mounted on cardan joints rather like marine chronometers. The instrument, which is sensitive to changes of position, is kept in a constant horizontal position, thereby ensuring optimal amplitude for the spiral balance-wheel.
Coordination is provided by an invention patented by ZENITH: a second gear train is the reference point for the swinging of the escapement axles and a differential gear with inverter compensates all the relative movements of the framework. The Zero-G Tourbillon, whose cage alone comprises 166 of the 294 parts that make up the device, 10 conical geared wheels with spiral teeth and 6 ball-bearings, was developed from the El Primero automatic caliber that beats at the record speed of 36,000 vibrations an hour.
