The Nautical first came out in 1961 and was used to warn divers when it was time to return to the surface. The 2013 version is a tribute to the watch.
Watchmaker Vulcain has introduced a limited edition version of the Nautical, which works for scuba divers under water.
This durable, charcoal grey layer with a low friction coefficient consists of an atomic lattice composed of the two forms of carbon: diamond and graphite. Diamondblack DLC (Diamond-Like Carbon) is applied using a coating process that faithfully mirrors the original surface finishes.

Diamondblack DLC consists solely of molecules of carbon and hydrogen arranged in a structure similar to that of diamond, producing a layer with excellent chemical stability and high corrosion resistance. Its proven biocompatibility enables prolonged contact with the skin without causing irritation.
It has a very high level of hardness, around 5,000 Vickers, compared to stainless steel, approximately 200 Vickers. This high-tech coating is used in the aerospace industry and in any application in which wear resistance and a low friction coefficient are essential.
