Vulcain successfully developed Nautical in 1961, making it one of the first episodes of the world's oldest diving watch ever. Legendary reproduction, courage in the abyss In the mid-twentieth century, regulator technology was introduced to convert the air inside a high-pressure cylinder into an air pressure suitable for divers to breathe. This technology has made scuba diving more commonplace and has promoted the use of professional dive watches R & D. Vulcain successfully developed Nautical in 1961, making it one of the first episodes of the world's oldest diving watch ever. Nautical features a triple bottom case that resonates with the sound box. The alarm sounds louder and louder, even on the bottom, to remind the diver to take the water at an appropriate time for safety. This year Vulcain introduced DLC (Diamond Like Carbon Coating) limited series, to pay tribute to the legendary Nautical diving watch. Nautical DLC Diving Table (Limited 100 pieces) Diamond-like carbon coating The atomic lattice of a carbon-black Diamond-Like Carbon coating consists of two carbon atoms, diamond (sp3) and graphite (sp2). Diamondblack? DLC coating technology can completely match the material surface texture, and only contains carbon and hydrogen molecules, the structure of the hydrogen atoms and diamonds similar to the structure, so the outer chemical properties are very stable, excellent corrosion resistance, and anti-allergy , Long-term contact with the skin does not cause discomfort; the other is the high hardness (about 5000 Vickers hardness, stainless steel is about 200 Vickers hardness), it is widely used in aerospace industry, any need to wear and low friction Operating system also have to apply.
