Owning a piece of living history is no small thing. With Zenith being one of the oldest luxury watch houses in operation, there is a special pleasure in celebrating tradition, innovation, and legacy. 

At the heart of this dashing Chronomaster we encounter the celebrated Zenith El Primero 3600 caliber, a high-frequency chronograph movement that works at the elevated frequency of 5Hz and allows for highly accurate 1/10th of a second chronograph measurements, which can be conveniently read via the scale upon the rugged fixed ceramic bezel. El Primero 3600 beats at 36,000 vph, possesses 35 jewels, and offers up 60 hours of power. It can be enjoyed via the exhibition caseback.

Attractive subtly multicolored subdials are prominent against the deep black-colored dial and offer up a small seconds counter as well as 60-second and 60-minute chronograph counters. We especially enjoy the stylish red-tipped center arm adorned with the iconic Zenith star.

Nestled between 4 and 5 o'clock there is a discreet date window, and luminescent hands and markers make for easy viewing in low light.

The stainless steel case measures 41 mm in diameter, 13.6 mm in height, and rests upon a fashionable rubber strap with fabric top layer, the strap is being fasted by a stainless steel deployant clasp. Additional case features include a push / pull winding crown, scratch-resistant sapphire crystal, and 100 m / 10 atm water resistance. 

Taken together, this Chronomaster's expert construction, robust movement, and attractive stylings make this a must-have Zenith that will surely enhance any collection.
