Claim 1:
2. The detent escapement according to claim 1, wherein the first arm of the detent carries a rest pallet against which the escape wheel is bearing by one of teeth of the escape wheel just before the start of the driving impulse, and a disengagement pallet against which the pivoting hook of the balance is bearing just before the start of the driving impulse, the pivoting hook being arranged so as to push back the disengagement pallet and to pivot the detent at the start of the part of the alternation of the balance where the impulse takes place, so that the rest pallet disengages from the tooth of the escape wheel with which the rest pallet is engaged and allows said escape wheel to provide the driving impulse to the balance, and the pivoting hook being arranged so that, during the alternation without impulse of the balance, the pivoting hook is retracted by performing a pivoting movement when the pivoting hook passes at a level of the disengagement pallet, so that a passage of the balance has no influence on the detent during said alternation without impulse, the detent also carrying a return pallet arranged so that the rest pallet again gradually penetrates in the perimeter of the teeth of the escape wheel when the escape wheel finishes providing the driving impulse to the impulse pallet of the balance.
