PVD (Physical Vapor Deposition) and DLC (Diamond-Like Carbon) are popular coating techniques used in watchmaking. PVD is a process where a thin layer of material, such as titanium nitride or black DLC, is deposited onto the watch case using a vacuum chamber. This coating provides increased durability and scratch resistance.

On the other hand, DLC is a specific type of PVD coating that uses carbon to create a hard and wear-resistant surface. DLC-coated watches often have a sleek and modern appearance due to their black color. The DLC coating not only enhances the watch’s aesthetic appeal but also provides excellent protection against scratches and wear.

Overall, PVD and DLC coatings offer significant advantages in terms of durability and aesthetics, making them popular choices for watch enthusiasts.
