PVD & DLC Coatings

Deep, durable, beautiful surface finishes — engineered to survive the wear a luxury object endures over a lifetime.

What it is

Physical Vapour Deposition (PVD) and Diamond-Like Carbon (DLC) are thin-film coating processes that bond an extremely hard, thin layer to a component in a vacuum chamber. The result is a finish that reads as solid colour or deep dark chrome, yet resists scratching, corrosion and fading far better than plating.

Applications & industries

  • Watch cases, bezels, crowns and bracelets in black, grey and warm tones
  • Jewellery and hardware requiring a durable coloured or dark finish
  • Eyewear frames and hinges where thin, even coverage is critical
  • Medical and precision components needing a biocompatible, low-friction surface

The process

1. Surface preparation. Components are finished and cleaned to the exact roughness the coating requires — the single biggest driver of a flawless result.

2. Deposition. In vacuum, the coating is grown layer by layer to a precisely controlled thickness and colour.

3. Inspection. Every batch is checked for adhesion, colour match and coverage against your reference standard.

Why Kierand

Decades spent finishing objects that people wear every day means we optimise for the failure modes that matter to a luxury brand — ghosting at the lugs, haze on polished faces, wear at contact points — not just a pretty first impression. Patented process know-how underpins how we prep and coat the hardest surfaces.
