Zenith Defy II Collection – Defy Classic Open El Primero

Designed like a racing car, the DEFY collection makes a powerful statement with its muscle-bound chassis, its racy profile, and athletic build. Its virile silhouette, dynamic lines and elegant power suggest a sport watch, but in a luxury version. Innovative materials used are in combination, including the famous ZENITHIUM®, an exclusive alloy .

The DEFY CLASSIC OPEN comes with a harmonic El Primero calibre, the SC 4021. The movement’s oscillations at the rate of 36,000 vibrations per hour can be seen through the window in the dial. Each detail has been well thought out: the power reserve with its indicator, the applied indexes and the open-work luminous hands. Available on a 46.5mm or 43mm stainless steel case or in steel and 5N brushed rose gold case with black or silver dial on rubber or stamped crocodile leather strap.
