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 ( 10 a ) 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 ( 9 b ) at least two stems ( 11, 13, 15 ) of different dimensions, offset by the same distance from the rotational axis ( 10 a ) 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 ( 12 a, 14 a, 16 a ) 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 ( 10 a ) of the studs ( 10 ).
