Zenith El Primero 21

Martina Richter reviews the Zenith Defy El Primero 21 chronograph.

Starting the chronograph of the Zenith Defy El Primero by pressing the large rectangular pusher at 2 o’clock comes with a huge surprise: a long, thin hand spins around the dial at lightning speed. It only needs 1 second for each rotation. And inside the titanium case, the mechanism that makes this possible hums along at this high-speed pace, with an oscillating system that beats at a rate of 360,000 vph. This permits the measurement and display of 1/100-second intervals: 360,000 vph equals 100 beats per second, with as many steps by the hand in the same time interval.
