Zenith Baselworld Novelty: El Primero Revival A386 May 14, 2019 Jewelry 63 Zenith sets the crowning touch to the festivities honouring its legendary 1969 El Primero high-frequency chronograph with a solid gold “revival” trilogy. The 38 mm case of this watchmaking icon, which is celebrating half a century of avant-garde and precision, appears clothed in this precious metal. To mark this anniversary, the three unisex models in white, rose or yellow gold are issued in 50-piece limited editions with a 50-year guarantee. El Primero has been writing the epic Zenith saga since 1969. For this golden jubilee, the world’s most accurate automatic chronograph arrays its original attributes in the radiant glow of white, pink or yellow gold. Its revolutionary mechanics capable of tenth-of-a-second measurement, together with its three emblematic counters, have made it a legend. A cadence of 36,000 vibrations per hour; an integrated column-wheel construction; a ballbearing-mounted central rotor; and over 50 hours of power reserve (a real feat for such a high frequency) have been the signature features of El Primero creations for half a century. As a fitting tribute, Zenith presents three 50-piece re-editions of the original model, complete with a 50-year guarantee ensuring the bright future and heirloom stature of this anniversary series.
