DEFY Extreme Diver: Designed for the Deep, Built for the Extreme
A modern descendant of ZENITH’s pioneering 1969 DEFY dive watches, the DEFY Extreme Diver is a contemporary instrument engineered for the most challenging underwater conditions. Housed in a 42.5mm micro-blasted titanium case, this rugged timepiece is as functional as it is striking. Sitting atop the fixed dodecagonal base is a unidirectional rotating bezel in black ceramic, fully filled with Super-LumiNova for optimal legibility. Precision operation is ensured, while the fluted bezel edge allows for easy handling, even with gloves.
Designed for saturation diving, the watch boasts a 600-meter water resistance and features a helium escape valve, alongside a screw-down crown flanked by protective guards. The star-patterned black dial is equipped with C1 Super-LumiNova markers and hands, punctuated by vivid yellow accents that ensure visibility in low-light conditions.

In a rare feat for a watch of such depth rating, ZENITH has integrated an exhibition case back that reveals the El Primero 3620 automatic movement, finished in a sleek modern black. The bidirectional winding system provides a robust 60-hour power reserve.

Completing the DEFY Extreme Diver is a micro-blasted titanium three-link bracelet, as well as two interchangeable strap options. The first is a durable black rubber strap with a Cordura-effect texture and folding clasp. The second, is a black and yellow single-piece fabric strap secured with a pin buckle. Thanks to the integrated quick strap-change mechanism, switching between options is effortless and tool-free.
