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.

With its vibrant skeletonized dial with splashes of red and blue color there are layers of capabilities to appreciate in this Defy El Primero 21 watch by Zenith.

First, beneath the scratch-resistant sapphire crystal we have a timepiece of robust offerings.

Zenith’s certified chronometer El Primero 21 movement is the most accurate and fastest manufacture chronograph on the scene. It offers a 50-hour power reserve and can be viewed through both the open dial and exhibition case back.

At its heart you will find two regulating organs and escapements: one beats at 5Hz for keeping the time while the other beats at a fabulous 50Hz to offer a true 1/100th of a second chronograph function. As such, there is a center red-tipped chronograph hand as well as a 30-minute counter at 3 and a 60-second counter at 6. Note the subtly rendered running seconds at 9.

In addition, there is a 1/100th of a second track in white and a Chrono Power Reserve indicator at 12.

The rugged Black ceramic case measures 44 mm in diameter, 14.5 mm in height and rests upon a Black ceramic bracelet with a tough titanium folding clasp. Other features include a 100 m / 10 atm water resistance and a push / pull winding crown.

From its legendary accuracy to its rugged construction, we are confident that this Zenith Defy El Primero 21 will make a wonderful addition to your collection.

Standout feature(s): Famed and highly accurate El Primero caliber; rugged Black ceramic case and bracelet with titanium clasp; convenient power-reserve indicator; unique skeletonized dial and exhibition caseback.
