Oscillation

When a pendulum or balance oscillates it moves between two extreme positions (A' and A''). The movement from one of these positions to the other and back equals one oscillation. Usually a balance produces 9,000 oscillations an hour, equivalent to 18,000 vibrations.

1 oscillation = 2 vibrations
