Diamond-like coating
Definition
DLC (Diamond-Like Carbon) is a carbon-based coating that gives watch cases exceptional hardness and a deep black color. In my experience as a craftsman, I've observed how this treatment not only protects the metal from scratches but also creates an elegant contrast with the dark leather straps I create. It's a finish I favor for luxury sports watches, where wear resistance must marry Italian elegance.
Frequently asked questions
How long does the diamond-like coating on watch buckles last?
The DLC coating on our Milano Straps buckles keeps its properties for years of daily use, thanks to its hardness of 2000-4000 HV on the Vickers scale. Durability depends on how intensively the buckle is used, but under normal conditions the coating keeps its original appearance without fading or visible wear for at least 5-7 years.
Can diamond-like coating be applied to all metals?
DLC adheres excellently to 316L steel and titanium, the materials we use for our Milano Straps metal components. The process requires specific surface preparation through sandblasting and ultrasonic cleaning to ensure perfect, long-lasting adhesion of the carbon-based coating.
How do you clean and maintain a buckle with diamond-like coating?
Our DLC buckles are simply cleaned with a damp cloth and mild soap, avoiding abrasive cleaners that could dull the surface. The anti-static nature of the diamond-like coating naturally repels dust and fingerprints, making maintenance much easier than with traditional finishes.
