About the Watch
Originally built in 1997, the El Primero "Rainbow" was made to specs set forth by the French Air Force. They had requested a chronograph capable of withstanding forces of up to nine to eleven G's, wide variations in pressure and temperature, and a dial that was extremely easy to read. This particularly colourful version is considered popular with collectors and offers a flyback function that allows zeroing and the immediate start of a new stopwatch measurement.
About the Brand
Whether exponents of the more artistic crafts or of ultra-technical skills, all are engaged in the task undertaken by Georges Favre-Jacot 150 years ago: that of mastering each gesture to enable free-spirited creation of mechanical marvels combining noble watchmaking traditions with avant-garde innovations. Famed for its legendary 1969 El Primero calibre enabling short-time measurements accurate to the nearest 1/10th of a second, Zenith has since developed over 600 movement variations. In this third millennium, based on this same DNA, but with renewed energy, the brand has blazed the trail for fascinating new vistas in time measurement with the launch of the Defy El Primero 21 and the Defy Lab. The former opened the world of hundredth of a second timing, a quantum leap in terms of performance and engineering, impressively combining the historic heritage of Zenith with the future of watchmaking; while the latter, winner of the Innovation Prize at the 2017 Grand Prix d’Horlogerie de Genève, challenged the very foundations of traditional watchmaking with the most accurate mechanical watch ever made. Energised by newly reinforced ties with a proud tradition of dynamic, avant-garde thinking, Zenith is writing its future… and the future of Swiss watchmaking.

5 Reasons for Vintage
Watches that only a few wearReason Nr. 1Nowadays, many high-quality watches are mass-produced. Vintage watches were often made in very small series with skilled craftsmanship instead of robots.
Quality that endures generationsReason Nr. 2In earlier eras, watches were designed to last forever, including the components. There is no such thing as obsolescence. That is what we consider quality at Zurichberg.
Polarizing and characteristic designsReason Nr. 3Today, only a few watch manufacturers can afford to launch polarising products and therefore produce watches that are aesthetically pleasing to all.
Value for MoneyReason Nr. 4Vintage watches are overall cheaper than new watches. This is because new watches fulfill the essential financial objectives for the manufacturers, whereas vintage watches are financially "depreciated", so to speak.
Longevity that feels greatReason Nr. 5We believe that in order to move towards a more sustainable future, it is absolutely necessary and logical to develop a sense for the quality of the past and to reuse products instead of producing new ones.
