DESCRIPTION

  • ZENITH El Primero Stratos

    The flight instruments in the cockpit of a fi ghter jet are subjected to abrupt variations in pressure, intense vibrations and violent accelerations – from 9G to 11G. Thanks to its robust construction, the ZENITH Stratos can withstand it all. As the faithful heir of the Rainbow Flyback model developed for the French Air Force in 1997, the Stratos is equipped with the world’s most accurate automatic chronograph movement – the mythical El Primero – as well as the Flyback function. Accuracy and reliability have been the watchwords of the Manufacture ZENITH since 1865. Very early on, this obsession with accuracy and precision played an important role in aviation and transport. Today, this Manufacture timepiece is becoming established in the fascinating world of military and sporting aviation, where performance and absolute confi dence in one’s team members take center stage. Clear for take-off !

    El Primero Stratos Flyback

    The Stratos Flyback comes in four other models: a steel version, a highly resistant black Alchron version, and two different black Alchron and gold versions. Alchron was specifi cally developed for the aeronautical industry and for automobile racing, but this hi-tech alloy is now being used in watchmaking. Its magnetic permeability is 50 times lower than that of steel. This material is also especially resistant to corrosion and boasts very impressive mechanical characteristics. Its Vickers hardness number is 210 HV. Before being integrated into the design of the Stratos, the Alchron was subjected to a battery of tests: its corrosion-resistance was tested in saline mists, tropical climates and artifi cial perspiration were simulated, and its impact-resistance was tested with a pendulum striker (a hammer-like steel pendulum fi xed to the end of a swinging arm that drops down and hits the case head-on at full force). It goes without saying that the true goal of these tests was to provide the high-precision El Primero caliber with the best high-strength alloy technology available.

    The Manufacture ZENITH : loyal to a visionary concept

    ZENITH has remained faithful to the visionary concept of its founder: to ensure that all its timepieces are entirely produced in-house. Each of its watches has been produced from start to fi nish by the Manufacture: over approximately nine months, craftsmen from eighty different trades work on each one in turn to guarantee that each watch benefi ts from expertise that has been handed down and perfected by ZENITH for the last one hundred and fi fty years. The fi ve different ZENITH Stratos models, all hand-crafted, are heirs to the watches and fl ight instruments that have equipped the instrument panels of Europe’s greatest military air fl eets.
