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.
