The Zenith Chronomaster Sport is one of the few examples of a timepiece inspired by the past that does not merely reproduce a vintage model. Its design casually mixes elements from the 60s, 70s and 80s with purely contemporary elements. The dial with three-tone counters, originally from 1969, is now considered a signature of Zenith chronographs.
The black polished ceramic bezel has a 10-second scale: a modern element based on a 1980s model and a unique feature of this watch. The new Chronomaster Sport has a steel case, is water resistant to 10 atmospheres and has all the characteristics of a latest generation sports chronograph.
The El Primero 3600 caliber is an updated and improved version of the classic Zenith automatic chronograph movement, launched in 1969 as the first high-frequency integrated automatic chronograph. This version features a special gear train which allows the central hand of the chronograph to make a revolution of the dial in 10 seconds, in steps of one-tenth each. It is also important to note that the power reserve has been increased from 50 to 60 hours.
Through the sapphire crystal caseback, you can observe the refined mechanics and try to count the 36,000 vibrations / hour (10 per second) of its very fast balance-wheel. The column wheel - the heart of the chronograph functions - is highlighted by a blue color which is also typical of Zenith chronographs.
The dial has high-profile features, starting with the rhodium-plated, faceted and luminescent baton hands with Super-LumiNova, and the applied, rhodium-plated, faceted and luminescent indexes also with Super-LumiNova.
The chronograph counters are guilloché engraved with a filets circulaires motif and arranged according to the classic tri-compax geometry (the 60-minute counter at 6 o’clock, the 60-second counter at 3 o’clock and the smaller seconds display is at 9 o’clock,). The tenths of a second are indicated by a flush central hand, with a red tip and a star-shaped counterweight, with the brand's logo. The classic date window is located between 4 and 5 o’clock.
