Abstract

The watch case of this inveniton includes means for fixing the crystal to the case having surfaces exposed at the exterior of the watch thus susceptible to being scratched. Such visible surfaces are protected by an armour formed essentially of a substrate made from a metallic carbide and a material covering the substrate such material having a hardness greater than 5000 HV0.25.
