The watch comprises a case (9) with a fixed part (10) in the shape of a bracket (20) and a mobile part (11) with a middle (21) and a movement (23) mounted onto the fixed part (10) so as to be able to swivel about a swivel axis (32) thanks to pivots (31) in order to realize a tilting motion of the mobile part (11) in two opposite directions. Two actuating mechanisms (44, 45) are mounted into the middle (21) and intended to transform the tilting motions into an action upon two control organs of functions of the movement that may be of the chronograph type. One thus obtains a watch without push-pieces, functioning precisely, having great stability and easy manipulation.
