A Defy for the deep-sea
While inspired by a long line of Defy divers from 1969 onwards, the Zenith Defy Extreme Diver is as modern as they come. Its singular and highly intricate design serve to enhance its depth-defying performance, which was conceived to take on extreme conditions where ice, water and mist present a host of challenges. Its 42.5mm angular case is crafted in titanium, a metal that not only boasts a significant weight-to-strength ratio but is also highly resistant to corrosion from salty seawater. The case is equipped with a helium escape valve for saturation diving. Above the fixed dodecagonal bezel, the ceramic unidirectional rotating bezel features grooved edges for a better grip when operating – even with gloves on. The bezel is engraved and filled with Super-LumiNova and bright colors for effortless reading underwater where light is scarce.
The oversized screw-down crown feature is protected by titanium crown-guards on either side. Just like the historical Defy A3648 from 1969, the Defy Extreme Diver is rated to 600 meters (60 ATM) of water-resistance, which happens to be 1,969 feet – a symbolic number for the Defy diver. It meets the ISO 6425 requirements for professional diver watches, which include ISO 764 for paramagnetism as well as ISO 1413 for shock-resistance, making it a comprehensive diver’s watch suited to the most demanding conditions.
Legibility is a key factor in the Defy Extreme Diver – and it shows. The dial’s oversized hands and applied hour markers feature three different pigments of “X1” grade Super-LumiNova with light emissions in blue, green and orange, making it easy to distinguish between the functions (hours, minutes and seconds). The bright orange accents are a nod to historical Defy diver models.
The Defy Extreme Diver is powered by the El Primero 3620-SC automatic high-frequency manufacture calibre with 60 hours power reserve, visible through a sapphire display back – an uncommon feature among diver’s watches. This version of El Primero features a paramagnetic escapement with key components in non-metallic silicon.
Completing the Defy Extreme Diver is its titanium three-link bracelet as well as two supplied straps. The first additional strap is in FKM rubber, matching the dial colour with a Cordura-effect texture that features vents on the side, allowing water to pass through. In line with Zenith's HORIZ-ON initiative to reduce the brand’s environmental impact and produce more sustainably, the Defy Extreme Diver also comes with an extra-long strap made of recycled fishing nets, intended to be worn over a wetsuit. It features specific end-pieces to pass the single-piece strap through and under the case for a secure fit.
