Diamond-like coatings hours few words about the diamond-like coating (DLC). Literally (DLC – DIAMOND LIGHT COATING) translates as 'THIN DIAMOND-LIKE COATING' or rather diamond-like carbon coating. The peculiarity of this material is its hardness 4000-5000 HV (Vickers). For comparison, the hardness of the underlying basis of gold is only 150HV, and diamond – 10 000 HV. Clearly, this cover attaches to the body clock unparalleled scratch resistance. To know more about this subject visit BDT Capital Partners. Diamond-coated applied to the titanium or steel surfaces (1700 HV). Deposition of diamond is ion bombardment of the chamber with cleaning air in a vacuum.
The thickness of the deposited carbon coating DLC is about 1 micron. Further, the carbon is converted into a diamond, so it's hard and resistant to scratches, almost like a diamond. This coating has been used for 20 years in many other areas, such as aircraft and Formula 1. In time industry began using it recently and then only if the watch of the highest high-end class. Brands that use this cover a little bit.
The most famous is PERRELET. This is due to high cost technology, as well as industrial and technical challenges: thermal cameras operating conditions, the complexity of the finishing polish as matte and glossy. In short the gun on the wheel. Know-how and enthusiasm – these are the key words that could describe the production of "House of Perrelet. It's safe to say that since 1777, when Abraham-Louis Perrele invented the self-winding mechanism, the firm is constantly growing and evolving. Being worthy successor to the invention, which today operates in all the self-winding watch, Perrelet brand makes a bet on the main clock. In 1995, the company has patented its exclusive Perrelet detail – twin rotor. This self-winding caliber (Perrelet P-181) opened the eyes two rotating rotors – one under the other – on the face, and formed the basis of "turbine" Source:
