GREY CM04 coatings


Especially developed for internal components

This grey CM04 coating has been specially developed for the internal moving parts of watches (rough movements, weights, etc.) and their specific constraints: handling, stone setting, engraving and other finishing operations.


PVD (Physical Vapor Deposition) is a metal deposition coating process that allows thin films of material to be deposited under vacuum using vapor.

For PVD coating the deposition temperature is usually between 80 and 150°C.

The deposit thickness is 2 +/-0.5 (micron)

HV 0.05 hardness is between 800 and 1000

Conforms to REACH and RoHS standards

The advantages

  • Excellent quality for money
  • Excellent results in watchmaking tests (climatic resistance, UV, etc.)
  • Gloss, satin or matt grey color depending on the substrate
  • Grey PVD can be deposited on all substrates (copper alloys, titanium, gold, steel and stainless steel, plastics)
  • Clean deposit
  • Good compromise between ductility and hardness
  • Homogeneity and reproductivity of the color
  • Homogeneity and reproductivity of thickness
  • Low temperature procedure
  • Respect of terminals
  • A grey PVD treated part can be detreated and retreated

  • Surcotec
