An underwater watch having a unidirectional rotatable circular bezel (1) mounted on the casing (3), characterised in that the unidirectional rotatable bezel (1) has a cylindrical portion having two or more inwardly projecting teeth (8) on its internal circumference and is mounted on the casing (3) by means of a circular support ring (2); the casing (3) has an upper toothed annulus (11) having a toothed portion with saw-teeth and has a cylindrical upper portion in which an annular groove (10) is formed; the ring (2) supporting the bezel (1) on the casing (3) is constituted by a split circular collar which is resiliently insertable in the annular groove (10) of the casing (3) and which has means cooperating with the inwardly projecting teeth (8) of the rotatable bezel (1) for the axial locking of said bezel, means for joining the rotatable bezel (1) and the support ring (2), and also means for ensuring the axial stability of the rotatable bezel (1) and cooperating with the toothed portion (11) of the casing (3) in order to ensure that the bezel rotates unidirectionally. |
