PROBLEM TO BE SOLVED: To provide a horological movement functioning at a high oscillation frequency. SOLUTION: The horological movement comprises a regulating device having an oscillation frequency (f) and escapements 11 and 12 for maintaining the oscillations of the regulating device. The escapements comprise an escape wheel 11 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. COPYRIGHT: (C)2009,JPO&INPIT |
