  • an escapement mechanism comprising an anchor driven by a low amplitude oscillating movement, provided with two pallets which engage the teeth of an escape wheel.
  • the escape wheel is subjected to a step-by-step rotational movement whose frequency is determined by the oscillation frequency of the pallet, itself aligned with the oscillation frequency of the sprung balance.
  • the oscillation frequency is approximately 4 Hz, or approximately 28,800 vibrations per hour (A/h).
  • An objective of good watchmakers is to ensure isochronism and regularity of the oscillations (or constancy of the rate) of the balance wheel.
