OSCILLATION

Figure 1

The regulating organ (balance, pendulum) completes one oscillation when it moves from one extreme position (A’) to the other (A”) and then returns to its initial extreme position (A’) (Figure 1).

One oscillation is equivalent to two alternations. The frequency of an oscillator can therefore be expressed using these two values, namely:

• Number of oscillations per second, e.g.: 3 Hz

• Number of alternations per hour. For the same example: 21,600 A/h

Figure 1

The regulating organ (balance wheel, pendulum) completes one oscillation when it moves from one extreme position (A’) to the other (A”) and then returns to its initial extreme position (A’) (Figure 1).

One oscillation is equivalent to two vibrations. The frequency of an oscillator can therefore be expressed using these two values, namely:

1. Number of oscillations per second, e.g.: 3 Hz
2. Number of alternations per hour. For the same example: 21,600 A/h
