Description
In the late 1990s the French Ministry of Defence was seeking for a watch for its fighter pilots. The goal was to find a chronograph capable of maintaining excellent precision even in extreme conditions of use – including violent accelerations from 9 to 11 g’s, variations in pressure and temperature, as well as vibrations and magnetic fields.
Zenith responded the bid for tender launched by the French Ministry of Defence by presenting the reliable and resistant Rainbow Fly Back model in 1997.
Its steel case had a diameter of 40 mm, therefore the readability from the big dial was outstanding and the accuracy of the Zenith El Primero calibre 400 under all conditions at the level desired by the French Ministry of Defence.
Excellent original condition. Showing minor signs of wear for age. Not polished. Becoming increasingly rare to source early models. A great investment timepiece. An important part of Zenith history.
