The latest Chronomaster Sport collection marks the beginning of new era for the quintessential Zenith sporty-chic chronograph. Once again pushing the boundaries of high-frequency precision, the Chronomaster Sport is the culmination point in Zenith’s unequalled legacy of automatic chronographs that combines the spirit of the El Primero A386, the form of the Chronomaster De Luca and the high-frequency performance established by the El Primero calibre for over 50 years in a sporty chronograph like no other – in both style and substance. Always moving towards building the future of watchmaking, Zenith has built on the foundation of the El Primero caliber with a marked increase in performance directly perceptible by the user. The new El Primero 3600 calibre offers even more performance and precision than its forebearer, with its ultra-readable 1/10th of a second display etched directly on its black ceramic bezel - the only watch to do so.
