By configuring a timepiece component to include an intermediate film provided on at least a portion of a surface of a base material formed by using a nonconductive first material as a main component and to include a buffer film stacked on the intermediate film and mainly composed of a second material having a tenacity higher than that of the first material, the timepiece component may be manufactured with high precision, the weight thereof may be reduced, and even when the base material is formed by using a brittle material such as silicon, the timepiece component becomes resistant to breakage and capable of exhibiting high strength when an impact is externally applied.

A watch has a mechanical movement with a force control mechanism arranged in a going train of the mechanical movement between an energy source and an escape wheel set connected to an oscillating oscillator to drive the escape wheel set always in the same direction of rotation. The escape wheel set meshes with a seconds wheel. A rotating locking element is arranged to cooperate with a stop member connected to this seconds wheel in order to lock this going train in a stop mode or to release this going train in a jump mode depending on the angular position of this seconds wheel. A flexure bearing with elastic strips is attached on the one hand to the seconds wheel and on the other hand to the movement support. The pre-wound flexure bearing is 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.
