Abstract: Disclosed is a tourbillon for a horology movement including a cage rotatably mounted on the horology movement, the cage bearing a regulating organ including a balance including a balance pivot pivotally mounted in balance bearings about a balance axis with an anchor including an anchor pivot pivotally mounted in anchor bearings about an anchor axis and arranged to cooperate both with the regulating organ and also with an escapement wheel including an escapement pivot pivotally mounted in escapement bearings about an escapement axis. The anchor and the escapement wheel are positioned relative to the balance so the distance between the anchor axis and the balance axis and the distance between the escapement axis and the balance axis are greater than the outer radius of the balance. Also disclosed is a movement including such a tourbillon as well as to a timepiece including such a movement.

Abstract: A natural escapement for a horological movement performing a succession of operating cycles each composed of a first and a second alternation of a balance which includes a balance wheel on an axis of which is adjusted a balance plate, this natural escapement including a first escapement wheel arranged to be driven by a second wheel, this first escapement wheel in turn driving a second escapement wheel, the balance plate carrying a balance pin wherein this balance plate causes the pivoting of an anchor at each of the first and second alternations, a first lever, pivoted about a pivot axis, being connected to a first arm of the anchor via at least one pivot joint, the anchor including a second arm extended by a second lever, these levers being arranged to respectively lock the first and second escapement wheels temporarily.

Abstract: The present invention relates to a direct escapement mechanism (1) having an escape wheel (2) provided with a series of peripheral teeth (3), and an anchor (4), having an entry-pallet (10) and an exit-pallet (11) each having a locking plane (10p, 11p) and also having a fork (43). It also comprises a pin (6) which can be rigidly connected to a regulating organ (5) to cooperate at each alternation of said regulating organ (5) with the fork (43) of the anchor in order to unlock at least partially said anchor from the escape wheel (2) as well as at least one impulse pallet (9) which can be rigidly connected to said regulating organ (5) to cooperate with a tooth (3) of the escape wheel to transmit a direct impulse to said regulating organ (5).
