Oris presents the new Carlos Coste Limited Edition IV, a high-performance diver's watch designed for free diving. It has a 46 millimetre titanium case, a unidirectional rotating bezel with a white SuperLuminova minute scale that stands out against a black ceramic insert to allow the diver to read the remaining dive time at a glance. The black dial features indexes and hands also in SuperLuminova, but in a bright orange colour, while the double-sided domed sapphire crystal with anti-reflective coating reduces light refraction. The watch is water-resistant to 50 atmospheres (500 metres). Another notable feature is the dark orange dot on the manual helium valve at 3 o'clock, designed to help divers quickly distinguish the valve from the date and time setting crown at 2 o'clock. The movement is a mechanical self-winding Oris calibre 743, based on the SW 220-1. The watch comes with a black rubber strap (alternatively, a titanium bracelet version is also available), equipped with the Oris quick-adjust system with a sliding slide buckle.
