Abstract
A timepiece including a first resonator oscillating at a first frequency and connected by a main gear train to a main energy source via a main escapement, a second resonator oscillating at a second frequency which is lower than the first frequency and cooperating with the main escapement in order to synchronize maintenance of the first resonator to the second frequency.
