Founded in 1865 by Georges Favre-Jacot, Zenith became one of the most prestigious Swiss watch manufacturers, notably due to the development of the legendary El Primero movement.
For over 148 years, the values of the Zenith Manufacture have been authenticity, daring and pleasure. This obsession with precision has led Zenith to earn 2,333 chronometry prizes and 8 medals, as well as to register 300 patents and to introduce 600 movement variations.
For Only Watch 2013, the Manufacture Zenith will introduce a unique piece, the Felix Baumgartner Stratos Prototype I/I.
One-of-a-kind model developed by the Manufacture and the only prototype ever produced to develop and test the El PrimeroStratos designed for Felix Baumgartner and which has become the first-ever supersonic watch.
In 1969, Zenith effectively launched the El Primero calibre by placing it on the landing gear of a Boeing 747 on the famous Paris-New York flight. Fully living up to the high expectations for this legendary movement, the watch was running as smoothly upon arrival as it had at the time of departure.
In 2012, it was from even higher, on the very edge of space, that Manufacture achieved a new historical feat as the creator of the very first watch to break the sound barrier (attaining a speed of Mach 1.25) in direct contact with the exterior.
Resistant to sudden changes in pressure and temperature, as well as to extreme vibrations, this exceptional watch is a concentrated blend of the brand’s identity codes: the three colours of the iconic counters are all there; the mechanism beats at the high frequency of the El Primero movement, the world’s first automatic chronograph calibre; and the model also features the Flyback and Striking 10th (displaying tenths of a second via the sweep seconds-hand) functions.
