Physical Vapor Deposition (PVD) is a widely used technique to apply protective and decorative coatings and finishes to kitcheware, tableware, house applians and other surfaces. This cost-effective technique provides enhanced durability, scratch resistance, and aesthetic appeal. There are various PVD coatings for watches available on the market, such as:

1. DLC (Diamond-Like Carbon) Coating – DLC is a highly popular carbon-based coating that is renowned for its exceptional hardness, low friction, and great scratch resistance. It is usually available as a glossy black or matte finish, giving watches a sleek, modern look.



2. Titanium Nitride (TiN) Coating – TiN is a golden-colored PVD coating that provides luxurious appeal to watches. It offers good scratch resistance and is well-compatible with metals like stainless steel. It is often used to create gold-colored watches without the use of real gold.



3. Titanium Carbon Nitride (TiCN) Coating – This is a combination of titanium nitride and DLC that offers a gray or gunmetal color. TiCN coatings have high hardness and excellent wear and corrosion resistance, thus, they are particularly suitable for sporty and rugged watches.



4. Titanium Aluminum Nitride (TiAlN) Coating – This PVD coating includes titanium, aluminum, and nitrogen and provides watches with a gray or black appearance. TiAlN coatings have high hardness and good wear resistance, making them suitable for high-performance and tool watches.



5. Rose Gold PVD Coating – This coating is created using gold, copper, and sometimes silver, resulting in a warm, reddish-gold color. It provides an elegant look to watches.

6. TiO rainbow color



When deciding on what PVD coating is needed, the watch manufacturer must consider the desired color, style, and performance characteristics. It is important to note that while PVD coatings enhance the durability and scratch resistance of watches, these can still gradually wear off due to extensive use.
