The bezel (2) allows the same reading direction to be kept for the indications (20) carried by a ring (4) able to rotate freely on a base (6) to which it is affixed to bring a selected indication (20) opposite a determined marking of the base (6) or of a dial (3). The indications (20) are marked on the outer surface of studs (10) each kept free in rotation about their rotational axis (10a) in a housing (30) provided through the thickness of the ring (4) and opening onto the base (6). Each stud (10) includes in its lower part (9b) at least two stems (11, 13, 15) of different dimensions, offset by the same distance from the rotational axis (10a) of the studs (10), and having an angular offset of less than 180�, each stem (11, 13, 15) being guided during rotation of the bezel (2) by a circular groove (12, 14, 16) formed in the base (6) and having a cross-section adapted to the dimensions of each stem (11, 13, 15), a radius equal to that of the circle (18) described by the rotational axis of the studs, the centres (12a, 14a, 16a) of each groove (12, 14, 16) having, with respect to the centre of the dial, exactly the same arrangement as the stems (11, 13, 15) with respect to the rotational axis (10a) of the studs (10). |
