El Primero Stratos Flyback
Zentih Watches, a Manufacture for which accuracy and reliability have been the watchwords since 1865, has recently launched the ZENITH El Primero Stratos Flyback, Rose Gold which follows in the tradition of military chronographs and is the faithful heir of the Rainbow Flyback model developed for the French Air Force in 1997.
The watch implements the movement with 36’000 vibrations per hour, a movement that has been developed and manufactured in-house for over 40 years. It has an automatic column wheel chronograph with a power reserve indicator. It is made of black Alchron, a high tech material that was specifically developed for the aeronautical industry and for automobile racing, but 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 of very impressive mechanical characteristics. Its Vickers hardness number is 210 HV.
Before being integrated into the design of the ZENITH El Primero Stratos, the Alchron was subjected to a battery of tests: its corrosion-resistance was tested in saline mists, tropical climates and artificial perspiration were simulated, and its impact-resistance was tested with a pendulum striker (a hammer-like steel pendulum fixed 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 ZENITH El primero Stratos Flyback is available with a steel case and black dial on a black alligator-leather and metal strap; with black Alchron case and black dial on a black alligator leather strap; with two-tone black Alchron and pink-gold case and black dial on a black alligator-leather strap.
ZENITH has remained faithful to the visionary concept of its founder: to ensure that all its timepieces are entirely produced in-house. The Stratos models are all handcrafted and heirs to the watches and flight instruments that have equipped the instrument panels of Europe’s greatest military air fleet.
