Abstract: A watch including a case (6) having a push-piece (8), movable in a radial direction, and a device (14) for locking the push-piece. The locking device includes a locking member (16) rotatably mounted about a central axis of the case and arranged to be actuated between a locking position, wherein the push-piece is stopped or blocked by the locking device so that the function cannot be activated by actuation of the control member, and an unlocking position wherein the push-piece is released and can then be actuated in said radial direction to allow the function to be activated. A rotating bezel (20) and the locking member are coaxial arranged so that they can each be rotatably actuated by the user independently of each other. Thus, the rotating bezel is independent of the locking function and can thus be dedicated to the chronograph mechanism and be in particular useful for diving.
