We will ship to the forwarder for free and the buyer is responsible for all customs and shipping from there.

    Product Description

    While inspired by a long line of DEFY divers from 1969 onwards, the 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 saltwater. The case is equipped with a helium escape value 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 colours 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 of water-resistance. It meets the ISO 6425 requirements for professional diver watches, making it a comprehensive diver's watch suited to the most demanding conditions. 

    Something of the signature in the contemporary DEFY line, the dial features a geometric pattern of engraved four-pointed stars. Available in black and blue with matching ceramic bezels, the metallic dials feature a sunburst finish, with rays emanating from the applied ZENITH star at 12 o'clock. The date at 3 o'clock is colour-matched to the dial. 

    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 Exteme Diver is powered by the El Primero 3620-SC automatic high-frequency manufacture calibre with 60 hours power reserve, visible through the sapphire display back- an uncommon feature among diver's watches. This version of the 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 color 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 sustainability, 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.
