Mechanical movement watch with a force control mechanism

A mechanical movement watch with a force control mechanism, and of a jumping seconds type, the force control mechanism being arranged in a going train of the mechanical movement, which is arranged between an energy source and an escape wheel set comprised in an escapement mechanism connected to an oscillator intended to be set in oscillation in normal operation by a drive generated by said energy source to rotate said escape wheel set always in a single direction of rotation at each half-oscillation of the oscillator, said escape wheel set meshing with a seconds wheel,

• wherein said force control mechanism comprises a rotating locking element arranged to cooperate with a stop member in conjunction with said seconds wheel to lock said going train in a stop mode or release said going train in a jump mode, depending on the angular position of said seconds wheel,
• and a flexure bearing with elastic strips attached to the seconds wheel, and to a support of the watch movement, said flexure bearing with elastic strips being in a pre-wound state in the stop mode and arranged to drive in rotation the seconds wheel and the escapement mechanism connected to the oscillator at each half-oscillation of the oscillator in the stop mode,
• and the going train allowing the rotating locking element and a seconds-wheel pinion coaxial to said seconds wheel to rotate in order to make a one-second jump in the jump mode,
• and also allowing the flexure bearing with elastic strips to be rewound while allowing the rotating locking element and the going train to be locked for the stop mode following the jump mode.
