Frequency

The number of oscillations per second, measured in Hertz (Hz). The balance makes a to-and-fro movement at a given frequency (two vibrations = 1 Hz). The higher the frequency, the more accurate the watch: 21,600 vib/h (3 Hz), 28,800 vib/h (4 Hz) and 36,000 vib/h (5 Hz).

The quartz in an electronic watch vibrates at a high frequency, generally 32,768 Hz (commonly abbreviated to 32 kHz).
