  • the movement of said pawl ensures a certain angle of return which makes it possible to prevent the balance from rebating, also preventing the barrel from emptying.
  • the return means is in the form of an independent spring, such as a bent wire or an elastic blade, one end of which is fixed in the blank, while the opposite end is attached to the pawl.
  • the pawl is mounted on a blank within a housing.
  • This mounting is carried out by means of an axis ensuring the fixing of said pawl on the blank.

This type of assembly therefore makes it possible to remove the pawl by unscrewing the pin, before emptying the barrel, said pawl still being able to be constrained by the tension of the spring but especially by the tension of the barrel, which is strongly discouraged to avoid any deterioration. of a component, or even a sudden expulsion of the pawl.

  • the pawl being free to rotate, the positioning of the meshing ratchet is considerably simplified.
  • the pawl can be mounted beforehand with said ratchet, and vice versa for disassembly.
  • said pawl can be slid under the axis before positioning the ratchet. It is only the subsequent positioning of the ratchet that keeps the ratchet in place. Therefore, once the ratchet is mounted, the pawl can no longer come out, which constitutes a security for the dismantling of the clockwork movement. In fact, it is then necessary to remove the ratchet first and to empty the barrel beforehand. Consequently, such an assembly makes it possible to further simplify the configuration, by dispensing with an axis in the form of fixing screws and the precise step of tapping the blank.
