The number of oscillations per second, measured in Hertz. The balance moves to and fro at a given frequency (two vibrations). The higher the frequency, the greater the accuracy: 21,600 vibrations per hour (3 Hz), 28,800 vibrations per hour (4 Hz) and 36,000 vibrations per hour (5 Hz). A high frequency, however, consumes more energy.
