The Rolex Submariner, a legend in the world of diving watches and a coveted piece in the luxury watch market, has consistently pushed the boundaries of horological innovation. While the classic steel and gold iterations remain iconic, the application of Physical Vapour Deposition (PVD) coating has added another layer of complexity and visual appeal to this already celebrated timepiece. This article delves deep into the world of PVD-coated Rolex Submariners, exploring its history, the technology behind it, its implications for the watch's aesthetics and durability, and the various models that showcase this fascinating finish.
Understanding PVD Coating: More Than Just a Pretty Face
Before we dive into the specifics of PVD Rolex Submariners, let's understand the process itself. Physical Vapour Deposition (PVD) is a vacuum-based coating technique that involves depositing thin films of materials onto a substrate – in this case, the Rolex Submariner's case and bezel. This process creates a significantly harder and more scratch-resistant finish compared to traditional plating methods like electroplating.
The process begins by placing the watch component in a vacuum chamber. The material to be deposited, such as titanium nitride (for black PVD) or gold or platinum (for gold or platinum-toned PVD), is then vaporized using various techniques, including sputtering or evaporation. These vaporized particles then travel through the vacuum and adhere to the watch component, forming a thin, uniform coating.
The advantages of PVD are numerous:
* Superior Hardness and Durability: PVD coatings are significantly harder than the underlying material, offering exceptional scratch resistance. This is crucial for a dive watch that might endure knocks and bumps during underwater adventures.
* Uniformity and Adhesion: The vacuum process ensures a consistent and uniform coating across the entire surface, resulting in a flawless finish. The strong adhesion of the PVD layer minimizes the risk of chipping or peeling.
* Variety of Colors and Finishes: PVD allows for a wide range of colors and finishes, from classic black and gold to more unusual shades. This opens up possibilities for creating unique and visually striking timepieces.
* Corrosion Resistance: PVD coatings provide excellent protection against corrosion, further enhancing the watch's longevity.
The Rolex Submariner and PVD: A Marriage of Form and Function
While Rolex doesn't officially produce Submariners with factory-applied PVD coatings in the same way they offer gold or steel models, the use of PVD is present in a subtle yet significant way. Many Rolex Submariners, particularly those featuring gold or platinum accents, employ PVD in the application of the hour markers and numerals on the bezel. The moulded, recessed markers and numerals of the 60-minute graduation are coated with gold or platinum via PVD, ensuring a consistent and long-lasting finish that complements the overall aesthetic of the watch. This application of PVD is less about creating a dramatic colour change (as seen in aftermarket DLC PVD coatings) and more about enhancing the durability and richness of the existing gold or platinum elements. This subtle use of PVD highlights Rolex's commitment to quality and precision in even the smallest details.
