Zenith Defy El Primero 21 Blue

Presented in 2017, the Defy El Primero 21 houses a newly upgraded automatic chronograph movement beating at a frequency of 360,000 A/H (50 Hz), enabling 1/100th of a second precision. The Zenith DEFY EL PRIMERO 21 is now available in an elegant true blue version.

The elegant and efficient TIMELAB-chronometer certified DEFY EL PRIMERO 21 BLUE features a gleaming titanium case with matching rhodium-plated hour markers and hands.

The open-worked dial elegantly displays a chronograph power-reserve indication at 12 o’clock, hours and minutes in the centre, small seconds at 9 o’clock, black 60-second counter at 6 o’clock and the DEFY EL PRIMERO 21’s trademark blue 30-minute counter at 3 o’clock, offset by the unusual and visually striking blue mainplate.

The DEFY EL PRIMERO 21 BLUE offers a choice of three striking straps from black rubber covered with a sophisticated blue alligator leather coating; the comfort of supple blue rubber; or the sleekness of unadulterated titanium, all with a titanium double folding clasp. This magnificent timepiece is endowed with a generous 50-hour power reserve and water-resistant to 100 metres.
