Extreme in both form and function. The DEFY Extreme Diver is the latest in a long line of purpose-built DEFY watches, going as far back as 1969. With a singular yet familiar and modernistic silhouette, this DEFY Extreme Diver’s highly intricate case design serves to enhance its depth-defying performance. Measuring 42.5mm in diameter, the 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 black 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 for effortless reading underwater where light is scarce.
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.
