Two additional straps included - one black fabric strap and one metal bracelet.
The DEFY Extreme Diver, a contemporary interpretation of ZENITH’s iconic DEFY divers dating back to 1969, represents a fusion of heritage and cutting-edge technology. This timepiece is engineered to excel in the most extreme conditions, where ice, water, and mist pose formidable challenges.
At its core lies a 42.5mm angular titanium case, ensuring both strength and resistance to corrosion, crucial for prolonged exposure to salty seawater. Designed for professional saturation diving, it features a helium escape valve and a ceramic unidirectional rotating bezel with Super-LumiNova for enhanced visibility in low-light underwater environments.
True to its lineage, the DEFY Extreme Diver maintains a water resistance of 600 meters (60 ATM), meeting ISO 6425 standards for professional diver watches. Its dial with a geometric pattern of engraved stars, offers exceptional legibility with oversized hands and hour markers coated in multiple grades of Super-LumiNova.
Powering the timepiece is the El Primero 3620-SC automatic high-frequency caliber, boasting a 60-hour power reserve and a paramagnetic escapement with silicon components, visible through a sapphire display back—an unusual feature in diver’s watches.
Completing its robust design is a titanium three-link bracelet and two additional straps, including one made from recycled fishing nets as part of ZENITH’s sustainability initiative, HORIZ-ON. This strap is specially designed for wear over a wetsuit, emphasizing the watch’s versatility and commitment to environmental responsibility.
