Abstract: The horological movement comprises a regulating device having an oscillation frequency (f) and an escapement for maintaining the oscillations of the regulating device. The escapement comprises an escape wheel having (N) teeth. The frequency (f) is at least equal to about 5 Hz, and the ratio between the number (N) of teeth and the frequency (f) is substantially equal to 5.
