A horological detent escapement for a horological movement arranged to transmit a torque from said horological movement to an oscillating regulating organ of said horological movement, the regulating organ comprising a first mobile body and the escapement comprising a second mobile body and an escapement wheel. Said escapement wheel being arranged so as to transmit, during a half-phase of each oscillation of the regulating organ, a torque to said regulating organ via a direct impulse. The second mobile body comprises an indirect impulse means arranged so as to be in contact with the escapement wheel during normal operation and be out of contact during the other half-phase of each oscillation of the regulating organ when the escapement wheel does not transmit torque to the regulating organ, so as to transmit torque to said regulating organ via an indirect impulse, following an inadvertent movement or inadvertent stoppage of the horological movement.

A detent escapement includes an escape wheel with teeth regularly spaced along a perimeter and a balance having an impulse pallet and receiving driving impulses via the teeth, the balance performing an alternation during which it receives a driving impulse and an alternation without a driving impulse, the detent escapement also including a hook pivotally mounted on the balance and held bearing by an elastic member against an abutment, the detent escapement including a pivotable detent which includes a first arm which collaborates with the escape wheel to block the latter before the start of the driving impulse, as well as a second arm to allow the escape wheel to disengage from its engagement with the first arm at the start of the driving impulse, and which limits the pivoting of this detent to only part of the oscillation of the balance, the detent being configured to again block the escape wheel after the latter has finished providing the driving impulse to the impulse pallet of the balance.

A micromechanical timepiece, and a method for making the same, having a plurality of mutually secured functional sub-assemblies stacked in a direction (Z) to form a multistage assembly, wherein each functional sub-assembly comprises a single semiconductor material and is secured to another sub-assembly via bridges made of the semiconductor material, and in that at least one sub-assembly comprises at least two portions, the portions being movable relative to each other and relative to another sub-assembly to which at least one of the portions is secured via at least one deformable link integrally formed between the portions.

A timepiece mechanism comprising a regulator, an energy distributing member a pallet fork controlled by the regulator to alternate in locking and releasing the energy distributing member, and a decoupling member elastically connected to the pallet fork and to the regulator. The decoupling member is arranged so as to oscillate between two stop elements.

A sprung balance type mechanical timekeeper, includes a spiral spring (10), a balance (20) and an escapement mechanism (30) connected by a point of attachment (12) to the spiral spring and arranged to sustain an oscillation of the balance. The escapement mechanism (30) is connected to the point of attachment (12) of the spiral spring by a chassis (40) pivoted about the axis (A) of the balance. An outer end (12) of the spiral spring (10) is attached to this transverse pert (40) at a location located on one side of the balance axis (A). The chassis (40) includes two branches extending on either side of the axis of the balance (20) and forming a rotary plate whose axis of rotation is coincident with the axis of oscillation of the balance (20). The escapement mechanism (30) is located on the other side of the balance axis (A) and acts on the pivoted chassis (40) so as to free its rotation and thus make the attached end (12) of the spiral spring rotate.

The invention relates to an escapement device (400) comprising a first escapement wheel (1), a second escapement wheel (2), and a brake-lever (3), said second escapement wheel being disposed between the first escapement wheel and the brake-lever, in particular the second escapement wheel coming into contact and engaging with both the first escapement wheel and the brake-lever.
