A timepiece pallet fork for a mechanical oscillator including an arbor allowing the timepiece pallet fork to oscillate about a pivot axis, first and second pallets configured to alternatively engage with an escapement wheel when the timepiece pallet fork oscillates, the first pallet being displaceable with respect to the arbor by absorption of energy, the first pallet being displaceable from a first upstream waiting position to a first downstream stopping end position which is offset compared to the first upstream waiting position, and a first arm having an intermediate section including an elastic bend, one end of the arm being fixed with respect to the arbor to form a first fixed end, the intermediate section of the first arm being located between the first fixed end and the first pallet and returning the first pallet towards the first upstream waiting position by the intermediate section being elastically deformable from a first configuration into a second configuration.

The invention relates to an escapement device of a timepiece that includes a first escape wheel, pivotally mounted about a first axis of rotation, comprising a toothing equipped with first teeth and with second teeth, and a second escape wheel, pivotally mounted about a second axis of rotation, comprising a toothing arranged to at least cooperate with the second teeth of the first escape wheel. Each second tooth of the first escape wheel has an arm shape comprising at least one extreme protrusion arranged to cooperate with the toothing of the second escape wheel.
