Escapement mechanism of a timepiece

An escapement device of a timepiece, comprising:

• a first escapement mobile element arranged to be engaged with a drive gear train of the timepiece,
• a second escapement mobile element engaged with the first escapement mobile element,
• a blocking mobile element arranged to cooperate with an oscillator of the timepiece, wherein:
• the first escapement mobile element comprises a first toothing comprising first blocking teeth,
• the second escapement mobile element comprises a second toothing comprising second blocking teeth,
• the first escapement mobile element is arranged to block the blocking mobile element in a first rest position with one of the first blocking teeth of the first toothing during a first step called first-rest step, followed by a second first step called first-impulse step,
• the second escapement mobile element is arranged to block the blocking mobile element in a second rest position with one of the second blocking teeth of the second toothing during a third step called second-rest step, followed by a fourth step called second-impulse step, wherein:
• during the second step called first-impulse step, the first escapement mobile element gives an impulse to the blocking mobile element, preferably with said one of the first blocking teeth, and drives directly one of the second blocking teeth of the second escapement mobile element with another of the first blocking teeth, and
• during the fourth step called second-impulse step, the second escapement mobile element gives an impulse to the blocking mobile element, preferably with said one of the second blocking teeth, and is driven directly via another of the second blocking teeth by one of the first blocking teeth of the first escapement mobile element.
