Abstract
A wrist-watch case includes a back that is screwed onto a spacer ring and an assembly of two caps and a crystal that forms one piece attached to the case-band by screws fastened into the caps from the underside of the case-band. This construction makes it possible to integrate a bracelet perfectly with the case through the caps, each cap forming an end link having the same appearance as the articulated links of the bracelet and adjoining the beveled edge of the crystal. This construction is particularly well adapted to the use of caps and links made entirely of hard metal.
