ABSTRACT:
A watch case is made of gold with a caseband-bezel (11) hollowed-out in order to diminish the weight of gold as much as possible. To avoid dents in the caseband-bezel the hollow (26) is filled with metal, for example brass, which also serves as a casing ring (10) to secure the movement (13) to the case. The installation of such casing ring in the caseband hollow is possible only if the ring is made in at least four segments (1, 2, 3, 4 ) which are placed side-by-side and which are held in place by means guided in a groove (6) formed in the ring.
