    • PROBLEM TO BE SOLVED: To provide a timepiece movement comprising a balance spring made of a ferromagnetic material with low sensitivity to an external magnetic field.SOLUTION: The invention relates to a timepiece movement comprising a sprung (7) balance (5) resonator (3) mounted between a bar (2) and a bottom plate (4), where the balance spring (7) is formed of a ferromagnetic material. According to the invention, the timepiece movement includes a magnetic polarizing device (15) for the balance spring for maintaining a predefined state of polarization in the balance spring (7) and including permanent magnetizing means which forms a magnetic field in the plane of the balance spring so as to totally or almost totally magnetically saturate the balance spring (7) in the absence of an external magnetic field. The invention concerns the field of timepieces.

    • PROBLEM TO BE SOLVED: To provide a pendulum device which can continuously work with small power and, at the same time, the size of which can be reduced and a method for supplying energy to pendulum.
      SOLUTION: In a pendulum device having a pendulum 20 constituted by hanging down a weight 9 with a wire 10, a vertical moving mechanism 30 which supplies energy to the pendulum 20 by exciting the pendulum 20 in the vertical direction in accordance with the period of the pendulum 20 is provided. Since the vertical moving mechanism 30 which excites the pendulum 20 in the vertical direction in accordance with the period of the pendulum 20 is provided, and the energy supply to the pendulum 20 by gravity shifting is utilized as a resonant phenomenon; a pendulum device which continuously works with very small power and a method for supplying energy can be realized by utilizing the energy supply to the pendulum 20 by gravity shifting as a resonance phenomenon.
