Abstract: A timepiece movement includes a magnetic escapement formed of a magnetic escape wheel with an annular magnetized structure and a pallet fork whose shaft is formed by a ferromagnetic material. The pallet shaft exerts on the escape wheel a magnetic disturbance torque due to the fact that the annular magnetized structure exhibits an angular variation of at least one defining physical parameter thereof, such that the magnetic attraction varies as a function of the angular position of the escape wheel and has a tangential component. A magnetic compensation pin is incorporated in the timepiece movement, this magnetic compensation pin being arranged such that the second magnetic disturbance torque that it exerts on the escape wheel exhibits an angular phase shift relative to the first magnetic disturbance torque generated by the pallet shaft, so as to compensate largely for this first magnetic disturbance torque.

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.
