Abstract
The piece of jewelry protected by a hard metal shielding may consist of a metallic watchband composed of elements jointed to each other. In this case each one of said elements comprises a body member 61 of a material suitable for machining, such as stainless steel, and a plate 64 of sintered hard metal which is secured to body member 61 by means of plugs 65 welded against the back side of plate 64 and riveted to body member 61. The upper surface of the watchband elements is thus protected against injuries which contacts with foreign bodies could produce. Since that face of the watchband elements is practically the only one which is visible, when the watch is carried, the watchband will keep its original appearance during all the time it will be carried.
