Definitions

  • the present invention relates to a set of flexible guides for a rotary watch resonator mechanism.
  • the invention also relates to a rotary watch resonator mechanism provided with such a set of flexible guides.
  • the sprung balance constitutes the time base of the watch. It is also called a resonator.
  • the Swiss anchor escapement mechanism has a low energy efficiency (around 30%). This low efficiency comes from the fact that the movements of the escapement are jerky, that there are falls or lost paths to accommodate machining errors, and, also the fact that several components transmit their movement via inclined planes that rub against each other.

  • the fixed support extends laterally on either side of the longitudinal axis in the rest position of the assembly, the blades of the first pair of uncrossed flexible blades being connected to the lateral ends of the fixed support, so as to approach from the fixed support to the first movable element.
  • the third movable element extends laterally on either side of the longitudinal axis in the rest position of the assembly, the blades of the third pair of uncrossed flexible blades being connected to the lateral ends of the third movable element, so as to deviate from the second movable element to the third movable element.

  • the discs are arranged close to a vertical axis 67 perpendicular to the longitudinal axis 57, so that the moment of inertia of the balance 70 around the longitudinal axis 57 is higher and the moment of inertia around the vertical axis 67 is weaker.
