Some of life’s most decisive moments happen in a fraction of a second. A tight race towards the finish line, a perfectly struck ball scoring a goal, or even an instinctive decision at the crossroads of life, these instances are what shape the future. Zenith accompanies those who are always on the move towards achieving their dreams with an equally fast-paced chronograph: the new Chronomaster Sport collection, capable of measurements with an accuracy of 1/10th of a second.


Rebirth of a Legend

The latest Chronomaster Sport collection marks the beginning of new era for the quintessential Zenith sportychic 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.


Built for Motion

A descendant of the Chronomaster lineage through and through, the unique heritage of this emblematic chronograph line unfolds with a more refined dial, an integrated steel bracelet with optimized comfort,
enhanced finishing details, an ever more accurate search for proportions and an extremely precise tenth of a second reading. Crafted in a sleek and robust steel case measuring 41 mm wide with pump-style pushers, the polished black ceramic bezel sets the new Chronomaster Sport apart from its predecessors. Graduated over 10 seconds, its bold contrast offers exceptional legibility on the periphery of the dial. The Chronomaster Sport comes in two references. Whether the black or white dial, both feature the signature El Primero tri-color chronograph registers in blue, anthracite and light grey, just like the A386 from 1969. Each
of the counters is graduated to 60 for an intuitive and instantaneous reading of the chronograph. Befitting the modern yet timeless aesthetic of this exceptional chronograph, the Chronomaster Sport comes on an
integrated steel bracelet similar to those conceived by Gay Frères, who supplied many of Zenith’s metal bracelets in the past. A textured cordura-effect rubber strap option with a steel deployant buckle is also
available.




El Primero Evolution

Always in the pursuit of improvement, the Chronomaster Sport line is equipped with a new version of the Manufacture’s most renowned movement, dubbed the El Primero 3600 calibre. With the experience gained
after over five decades of the El Primero and high-frequency chronographs in general, Zenith is able to precisely offer a 1/10
th of second display from the 5 Hz (36’000 VpH) escapement, as well as an extended power reserve of 60 hours. Visible through the sapphire display back, the new architecture is strikingly evident, revealing a blue column wheel and open rotor marked with the five-pointed star Zenith. The Chronomaster Sport asserts itself as a sporty companion for all of life’s moments where even a fraction of a second is an instance of performance.


ZENITH: TIME TO REACH YOUR STAR.

Zenith exists to inspire individuals to pursue their dreams and make them come true – against all odds. Since its establishment in 1865, Zenith became the first watch manufacture in the modern sense of the term, and its watches have accompanied extraordinary figures that dreamt big and strived to achieve the impossible – from Louis Blériot’s history-making flight across the English Channel to Felix Baumgartner’s record-setting stratospheric free-fall jump. With innovation as its guiding star, Zenith features exceptional in-house developed and manufactured movements in all its watches. From the first automatic chronograph, the El Primero, to the fastest chronograph with a 1/100th of a second precision, the El Primero 21, as well as the Inventor that reinvents the regulating organ by replacing the 30+ components with a single monolithic element, the manufacture is always pushing the boundaries of what's possible. Zenith has been shaping the future of Swiss watchmaking since 1865, accompanying those who dare to challenge themselves and break barriers. The time to reach your star is now.


About the Zenith Ref. A386

The Zenith A386 is a significant reference within the El Primero lineage, recognized for its tri-color sub-dials and robust chronograph functionality. It was among the earliest watches to house the groundbreaking El Primero high-frequency automatic chronograph movement, setting a benchmark for precision and performance in its era. This reference is a foundational piece that established many of the design codes and technical capabilities that would define Zenith's chronograph offerings for decades.

The A386 features a distinctive stainless steel case, often characterized by its tonneau-shaped profile and pump-style pushers. Encased within is the celebrated El Primero caliber, an integrated automatic chronograph movement operating at a high beat rate. The watch typically includes a domed crystal, contributing to its vintage aesthetic and providing clear legibility of the dial.

For collectors, the A386 holds considerable appeal as an original example of a historically important chronograph. Its enduring design and technical innovation make it a sought-after reference, representing a pivotal moment in watchmaking history. The various dial executions and case finishes across its production run offer collectors a range of options, each contributing to the rich narrative of this iconic model.

That hurts the modicum of scientific training I received. Would you write 60 minutes on top of an hours counter? Does not make any sense
