Abstract
The watch case of this invention includes a caseband (1) hollowed out in the form of a vault (10). Such caseband includes first (5) and second (6) cylindrical support surfaces cooperating respectively with a crystal (2) and a back cover (3). Three blocks (7), unitary with the caseband, are arranged within the hollowed-out vaultlike space. Each block bears a projection (11) extending towards the movement (17) borne by the case, said projection having an upper snap (12) on which rests a flange (15) supporting the crystal and a lower snap (13) on which rests a casing ring (16) on which the back cover bears.
