Mechanical movement watch with force control mechanism

A mechanical movement watch (1) with force control mechanism, and of the jumping seconds type, the force control mechanism being disposed in a finishing train (5, 8, 9, 10) of the mechanical movement, which is arranged between an energy source (25) and an escape wheel set (11) that includes an escapement mechanism linked to an oscillator (14) intended to be set in oscillation in normal function by a driving force generated by said energy source in order to make said escape wheel set (11) rotate always in a single direction of rotation at each half oscillation of the oscillator (14), said escape wheel set (11) meshing with a seconds wheel (2),

• wherein said force control mechanism comprises a rotary locking element (7) arranged to cooperate with a stop member (3) mechanically linked to said seconds wheel (2) in order to lock in a stop mode or release in a jump mode said finishing train according to the angular position of said seconds wheel (2),
• a stop member spring (4) in order to rotate the seconds wheel (2) and the escapement mechanism linked to the oscillator (14) at each half oscillation of the oscillator (14) in stop mode, and
• a finishing train making it possible for the rotary locking element (7) and for a seconds pinion (5) coaxial to said seconds wheel (2) to rotate in order to perform a jump of one second in jump mode,
• and also making it possible to perform a rewinding of the stop member spring (4) in connection with the seconds pinion (5), while making it possible to lock the rotary locking element (7) and the finishing train for the stop mode following the jump mode.
