More Information
Summary:The invention concerns a escapement lever (1) for the escapement mechanism of a timepiece movement, including at least one fork delimiting a notch (2) which includes horns (3; 4) arranged for cooperating with a balance. Said fork notch (2) includes, in at least one said horn (3; 4), a slot (5, 6) and/or a chamber (30), wherein said slot (5; 6) and/or chamber (30) is arranged to confer elasticity on the corresponding horn, which softens the shock at each impulse, by absorbing part of the impact energy, and then returning it subsequent to said impact.
