The Zenith El Primero Zero-G Multi-Dimensional Tourbillon will be debuting at Baselworld 2008 in April. 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.

Bringing the Tourbillon Zero G and the Defy Xtreme range together produces an unforeseen design, a perfect alchemy of engine and bodywork. A figure 8 on its side, symbolizing infinity or a lucky number, is drawn around the hours and minutes display at 11 o’clock and around the opening of the phenomenal Tourbillon at 5 o’clock.

A multi-layered dial of Hesalite glass, carbon fiber and aluminum beneath two sapphire glasses, a blackened titanium case that is waterproof at 1000 meters, a black shot-peened titanium case, a protected crown, helium valve and titanium bracelet with Kevlar inserts and high-temperature resistance are the features that make this an extreme sports timepiece.
