Q: What is PVD gold coating?
A: PVD (Physical Vapor Deposition) deposits a thin layer of gold (typically 0.2-1μm) in a vacuum chamber. Unlike electroplating, PVD creates a harder, more wear-resistant coating with excellent adhesion and consistent color.
Q: Can you match specific gold color tones?
A: Yes, we can match 1N-14K (light yellow), 2N-18K (yellow), 3N-22K (pink/rose), 4N-23.5K (red), and 5N (deep rose) PVD gold tones to match your watch case and bracelet.
Q: What knurling patterns can you produce?
A: Diamond (cross-hatch), straight (axial), annular (ring), rope, and custom patterns. Diamond pitch from 0.3mm to 1.5mm. Knurling on diameters from 3mm to 50mm.
