Worn by devotees of Fine Watchmaking in general as well as by exceptional athletes and by stars such as the Rolling Stones, the El Primero Chronomaster choose Las Vegas as the venue to unveil its latest interpretations. Alongside the generous palette of new dial colors and a reaffirmed concern for elegance, the famous opening revealing its mechanical treasure is the must-have feature for any discerning collector.
This design has been embedded in the Zenith DNA since 1969, when the Manufacture overlooking Le Locle (a watchmaking city in the Neuchâtel mountains) presented the legendary El Primero caliber, the world’s most accurate series-made chronograph movement. The epitome of performance and reliability, the El Primero Chronomaster asserts itself as a sports chronograph beating at the impressive rate of 36,000 vibrations per hour and displaying tenth-of-a-second precision.

"The cult “king of chronographs” El Primero caliber opts for a blend of strength and elegance"
Now equipped with a silicon lever and escape-wheel, it guarantees its wearer COSC certification, synonymous with ever appreciable reliability. Visible through the back of the brushed steel case, the oscillating weight of the self-winding movement adorned with a Côtes de Genève motif stages a perpetually moving show. It can also be admired in action through the 10 o’clock opening on the skilfully structured sunburst dial, featuring a timeless yet modernized design that now comes in three elegant and eminently seductive versions: blue with two snailed tone-on-tone counters; anthracite with two-tone blue and silver-toned counters; and blue with anthracite and silver-toned counters.
Individuals with refined tastes can also adopt these colors on the new El Primero 36’000 VpH models, as well as the new Elite range, of which the more classically understated aura and slender refinement are much appreciated by Zenith aficionados.
