A mechanical regulator for horology including an escapement collaborating with an oscillator provided with an inertial element oscillating in an oscillation plane by virtue of a return element. The escapement includes a pin rigidly connected to the inertial element, an anchor including a fork collaborating with the pin, and two pallet stones collaborating with teeth of an escape wheel. The regulator is configured such that, during a first frictional locking phase that occurs before an unlocking phase, and during a second frictional locking phase that occurs after an impulse phase, the pin is in contact with the fork so as to push same, and a tooth of the escape wheel is in rubbing contact with one of the pallet stones.

A flexible guide for a rotating resonator mechanism, in particular of a horological movement, the guide including a fixed support, an element that is capable of moving relative to the fixed support, at least one main flexible blade allowing the movable element to move relative to the fixed support by bending the one or more main flexible blades via a rotary motion about a centre of rotation, the flexible guide being arranged substantially in one plane, and includes at least one translation table joined to one end of the main flexible blade, the main flexible blade and the translation table forming a pair connected to the fixed support, to the movable element, or to an intermediate movable part, such that the translation table is configured to move in translation at least in part under the effect of the bending of the main flexible blade.

A shock-absorber and/or vibration-absorber device is proposed, comprising at least one flexible element able to deform under the effect of a stress; said device being remarkable in that it includes at least one so-called dissipative layer made from a material having a shear modulus lower than the shear modulus of the flexible element, a shock-absorbing factor greater than the shock-absorbing factor of said flexible element, and at least partially secured to said flexible element such that a flexion of the flexible element, under the effect of a stress, provides shearing of the dissipative layer making it possible to dissipate at least part of the energy from said stress. A method for manufacturing said shock-absorber device is also disclosed.
