Vulcain Vulcain Nautical Dlc Legend Reappearance, Yong Chong Abyss

In 1961, Vulcain Vulcain successfully developed Nautical, which became one of the first diving dive watches in history. Nautical has a triple bottom cover that acts as a resonance box, the alarm sounds louder, and it is clear and audible even at the bottom, reminding divers to enter the water at the appropriate time to ensure safety. This year Vulcain launched a limited series of DLC (Diamond-Like Carbon Coating) to pay tribute to the legendary Nautical diving watch.

Diamond-like carbon coating
The atomic lattice of the carbon black Diamond-Like Carbon coating consists of two carbon atoms, diamond (sp3) and graphite (sp2). Diamondblack ™ DLC coating technology can fully match the texture of the material surface and contains only carbon and hydrogen molecules. The structure of the carbon and hydrogen atoms is similar to that of diamond, so its outer layer has very stable chemical properties, excellent corrosion resistance, and anti-sensitivity It will not cause discomfort when contacting with the skin for a long time. Another characteristic is that the hardness is extremely high (about 5000 Vickers hardness, stainless steel is about 200 Vickers hardness), so it is widely used in the aerospace industry. The operating system can also be used.
