Sandblasting apparat with 4 barrels Harnisch+Rieth P-G 400
Many details of the watch are processed sandblasting. In just a few minutes, the surface becomes matte, and the burrs, the scratches and the damage are dusted out. It is possible to process the most inaccessible corners on the surface of a part that can not be made by other ways of refining. Sandblasting is another means of decorating the watch.
