Abstract: The present invention concerns regulating members for a mechanical timepiece, specifically a system based on the magnetic interaction between a resonator, in the form of a tuning fork for example, and an escape wheel, called a “magnetic escapement”. The system is characterized in that there are several areas of magnetic interaction between the resonator and the escape wheel which are arranged such that the torques produced at the escape wheel by these interactions compensate each other if the escape wheel is not synchronized at the frequency of the resonator. This results in negligible torque in the escape wheel when the latter rotates slowly in the direction of the arrow or the opposite direction. This allows the timepiece to start with a low mainspring torque and without any start procedure or device and provides better resistance of the timepiece against a loss of synchronization in the event of a shock.

Abstract: Regulating members for a mechanical timepiece, specifically a system based on magnetic interaction between a resonator, in a form of a tuning fork for example, and an escape wheel, as a magnetic escapement. In the system plural areas of magnetic interaction between the resonator and the escape wheel are arranged such that torques produced at the escape wheel by the interactions compensate each other if the escape wheel is not synchronized at the frequency of the resonator. This results in negligible torque in the escape wheel when the escape wheel rotates slowly in a direction of an arrow or opposite direction. This allows the timepiece to start with a low mainspring torque and without any start procedure or device and provides better resistance of the timepiece against a loss of synchronization in event of a shock.
