　　Introduction to the Zenith El Primero Stratos Flyback Rainbow watch

　　The 1997 edition of the El Primero Stratos Flyback Rainbow watch

　　Zenith has always been bold in embracing technical challenges, designing the Rainbow Flyback model in 1997 according to specifications established for the French Air Force. This timepiece offered exceptional performance and durability, operating seamlessly even under extreme conditions. Today, Zenith draws inspiration from this highly precise timepiece to design a sporty model: the El Primero Stratos Flyback Rainbow watch. This watch is released as a limited edition of 250 pieces, available exclusively at Zenith boutiques.

　　In 1865, the manufacture's founder, Georges Favre-Jacot, brought all watchmaking crafts under one roof to continuously develop and update production techniques, aiming to design the most precise and reliable watches of the era. The first integrated manufacture in watchmaking history was thus born, establishing Zenith's relentless pursuit: to push precision timekeeping to its absolute limit. More than 150 years later, the brand still upholds the founder's visionary spirit, remaining a leader in the field of precision timekeeping with a total of 2,333 awards. Zenith's timepieces embody cutting-edge technology, serving as milestones in contemporary watchmaking history. To date, the brand holds over 300 patents and has developed more than 600 movements, all of which are developed and produced in-house by the manufacture.

　　The world's most precious chronograph

　　In 1969, Zenith launched the El Primero chronograph, creating a legend. This was the first automatic chronograph in the manufacture's history, with a high frequency of 36,000 vibrations per hour, capable of measuring time to one-tenth of a second. To this day, it remains the world's most precious chronograph. Therefore, when the French Ministry of Defence requested the development of a pilot's watch suitable for fighter jets, it was only natural for Zenith, which had been renowned in aviation since the early twentieth century, to take on the task.

　　The specifications were very clear: to develop a watch capable of maintaining precise timekeeping under all extreme conditions, such as sudden acceleration from 9G to 11G, rapid changes in pressure and temperature, intense vibrations, and magnetic field influences. Faced with such a severe challenge, the manufacture once again pushed boundaries to perfect the watch's reliability and robustness. In 1997, the manufacture introduced the Rainbow Flyback model.

　　Today, the manufacture reinterprets this legendary watch in a limited edition of 250 pieces, available exclusively at Zenith boutiques. This El Primero Stratos Flyback Rainbow watch is powered by the El Primero 405 B column-wheel automatic mechanical movement, which operates silently. This chronograph has a high frequency of 36,000 vibrations per hour, measuring time to one-tenth of a second, and features a date display, a telemetric scale, and the flyback function, which is particularly crucial during flight. While a standard chronograph requires three button presses to stop, reset, and restart, the flyback function on this watch completes all three operations with a single press.

　　The case is crafted from lightweight and robust black Alchron titanium-aluminium alloy, measuring 45.5 mm in diameter, and features a scratch-resistant aluminium ring on the rotating bezel. The curved sapphire crystal is inspired by the fuselage windows used for navigation in aircraft. Through the transparent sapphire crystal caseback, the inner workings of the world's most precise movement are fully visible. The dial features a coloured minute counter at 3 o'clock, identical to the original model used by fighter pilots, ensuring clear readability even at night in an infrared-lit cockpit. Additionally, the hour counter is located at 6 o'clock, and the small seconds are at 9 o'clock. The white Super-LumiNova hour markers contrast sharply with the black dial and case, while the chronograph seconds hand is finished in a striking red. A telemetric scale is engraved on the outer edge of the dial, adding depth to the overall aesthetic. The El Primero Stratos Flyback Rainbow watch possesses a unique, masculine style, paired with a highly sporty black rubber strap and a black PVD-coated folding clasp.
