Abstract (en)
[origin: EP2570866A1] The timepiece (1) has a resonator (R1) oscillating at a preset frequency and connected to a main energy source (B2) by a main gear train (T2) via a main escapement (D2). Another resonator (R2) oscillates at another frequency, which is lower than the former frequency. The latter resonator is connected with the main escapement so as to synchronize maintenance of the former resonator to the latter frequency, where the main escapement is detent escapement and comprises a single escape wheel cooperating with two detents that are controlled by the resonators.
