Surface finishing in the watch industry

BWB transforms metals into precious pieces of jewellery with skilled craftsmanship and the right surface technology. For this purpose, it can draw on more than 40 years of experience in bringing together extremely small parts by means of welding and soldering processes, decorative blasting and a wide range of electrolytic surface treatments.

The BWB Group also offers a wide range of decorative effects for aluminium parts: A broad spectrum for colour anodising, individual special colours and high-precision aluminium sub-eloxal printing AloxPrint.

In the watch sector we carry out surface refinements of steel, stainless steel, titanium, aluminium and all precious metals and would be pleased to advise you on your project.
