In 1969, Zenith launched El Primero, the first ever fully integrated automatic column-wheel chronograph movement, enabling 1/10th of a second precision. Half a century later, Zenith once again defied tradition and pushed all existing boundaries, leading us into the world of 1/100th of a second accuracy. The Zenith Defy El Primero 21 is now available in a bold mix of black and blue tones as an exclusive limited edition of 250 pieces, available solely at Zenith boutiques around the world.
The Zenith Defy El Primero 21 chronograph boasts an outstanding frequency of 360,000 vph (50 Hz), ten times that of its El Primero predecessor, enabling 1/100th of a second precision. The inner bezel bears a scale graduated from 1 to 100 around which a 1/100th of a second hand sweeps at a lightning speed of one turn per second. Housed in a 44mm Midnight Black ceramic case, the open dial of the model offers an unobstructed view of the chronograph movement, finished with a Zenith Blue hue.
