Abstract (en)
[origin: JP2015096852A] PROBLEM TO BE SOLVED: To provide a regulating system capable of changing positional energy of a power spring at a time point or substantially the time point when speed of a trank roller becomes zero.SOLUTION: A regulating system 110 for a timepiece movement 12 comprising a first sub system comprises: a first oscillator O111 comprising a first trank roller B111 and a first hair power spring S111; a first displacement element M111 of the first hair power spring S111; and a first actuation element A111 of the first displacement element M111 at a time point or substantially the time point when the speed of the first trank roller B111 becomes zero.
