In the El Primero 21 from the Zenith Defy collection, the heritage brand builds on its early successes and redefines mechanical peak performance: equipped with two separate escapements for the time and chronograph functions, it beats at an incredible 50 hertz (360,000 vibrations per hour) at the push of a button, thereby enabling the measurement of hundredths of a second. Don't lose any time and experience the chronograph of the 21st century on your own wrist!

Two escapements, two power reserves

As an exclusive hallmark of the Zenith Defy El Primero 21, its rapid chrono hand stands out: instead of displaying the measured seconds as usual, it races across the dial at one full revolution per second and, when stopped, presents the hundredths of a second on the outer scale. The El Primero 21, in turn, shows the full seconds of the measurement on a subdial at six o'clock, which is complemented by a 30-minute display next to three o'clock and a small, three-bladed seconds at nine o'clock.

Since 100 hand beats per second come with extreme energy consumption, Zenith's engineers devised an ingenious solution: when the chronograph function of the Defy El Primero 21 is deactivated, the time display is ensured by a regular 5-hertz escapement (36,000 vibrations per hour) with 50 hours of power reserve. Only when the stop function is started does the separate, ten-times-faster chronograph escapement engage. The El Primero 21 displays its power reserve of around 50 minutes by means of a red, highly legible bar below the 12 o'clock position.

Zenith Defy Automatic

With the Zenith Defy El Primero, two worlds come together in a wonderful way. Defy is the Zenith line that combines futuristic aesthetics with as much innovation as possible. El Primero is the name of the caliber that is probably the most famous in the world, as it was the world's first automatic chronograph caliber. And yet this fits together: which movement ultimately stands for more innovation than the Primero, given that it has been continuously developed over the past 50 years. The El Primero 9004 is used in the Zenith Defy Automatic. Anyone looking for a Zenith El Primero with a rubber strap and titanium case should take a closer look at the Zenith Defy Automatic variants.

Innovative materials in an elegant retro case

The visionary mechanics are matched by first-class everyday functionality. The 44-millimeter tonneau case guarantees not only high wearing comfort but also 100 meters of water resistance and is available in four materials: while carbon, ceramic, and titanium impress with the highest stability and pleasant lightness, 18-karat rose gold marks the pinnacle of exclusivity. Entirely in the style of the timeless Defy Classic collection, the El Primero 21 rounds off its overall appearance with a sapphire crystal case back - a fitting complement to the skeletonized dial of most models. And if you want to take the groundbreaking design principle of the time hand to the extreme, the strictly limited Double Tourbillon series offers a separate tourbillon for the time and chronograph escapements.
