Watch-making quality standards

Bar turning and CNC making department

Watch-making quality standards

This activity comprises two sectors that concentrate on watch-making. The first is the production of turned plastic seals. These components are used to seal the case-back or the bezel. They are machined on high-precision revolver and CNC lathes.

The other type of product is watch casing rings. They are bar turned on CNC lathes then finished on 5-axis CNC machining centres for the milling, drilling and tapping operations. Our workshops are fully air-conditions to guarantee extremely high-precision products.

We also manufacture inner bezels and diamond-ground bezels.

Production facilities

  • 9 precision revolver lathes for bar work with a bar passage diameter of Ø 55mm
  • 6 CNC turning lathes of the same capacity
  • 2 CNC lathes with bar passage diameter of Ø 50mm and Ø 42mm, plus automatic supply machine
  • 7 5-axis machining centres
  • 1 4-axis machining centre
  • CNC finishing lathes, divider milling machines, drilling machines, tapping machines
  • 4 vibration finishing machines
