Abstract: A horological device including an oscillator of a watch and device for stopping this oscillator embedded in a carriage of a tourbillon or karussel, including a rod arranged to axially push a lifting finger into an active blocking position, against a first spring tending to recall same axially into a rest position in which it bears against a carriage wheel, which lifting finger includes a ramp radially repelling a stop finger against a second spring tending to radially distance same from the axis, which stop finger is remote from the axis when the lifting finger is in the rest position thereof, and, in the active blocking position of this lifting finger, the stop finger can interfere with a stop cam integral with a wheel set of the oscillator, in an angular position remote from the dead center position of the oscillator.

Abstract: A regulator device (200) for a watch movement has (a) an inertial element (11) of a resonator (10) of inertia I, pivoted about a first axis (A1) and inscribed within a cylinder of diameter D centered on the first axis; (b) an escapement mobile (30) of inertia I3, pivoted about a second axis (A3) and inscribed within a cylinder of diameter D3 centered on the second axis; and (c) a blocking member having (i) a first blocking lever mobile (20a) of inertia I2a, pivoted about a third axis (A2a) and inscribed within a cylinder of diameter D2a centered on the third axis; and (ii) a second blocking lever mobile (20b) of inertia I2b, pivoted about a fourth axis (A2b), inscribed within a cylinder of diameter D2b centered on the fourth axis, the axes (A3, A2a, A2b) contained within a cylinder centered on the first axis (A1) and of diameter D?<D.

Abstract: A single direction coupling device, including a first transmission member (10) fitted with a first saw-like contrate toothing (13), mobile in rotation about an axis XX and axially positioned by an elastic member (11), and a second transmission member (14) fitted with a second saw-like toothing (17), mobile in rotation about an axis YY, meshed with the first transmission member (10), characterized in that the XX axis is perpendicular to the YY axis.

Abstract: A tourbillon for a watch having a setting device for setting the hands of the watch includes a circular balance wheel that can swivel about a swivel axis. In addition, an escapement is provided that consists of a pallet and an escape wheel, the balance wheel and the escapement arranged on a base plate. A balance wheel shaft of the balance is rotationally mounted with its one end on the base plate and with its other end on a cage that surrounds the balance wheel like a basket. The cage comprises, outside of the radially encircling periphery of the balance wheel, a number of interspaced pillars fastened to the base plate and forms, with the base plate, a rotating mount which can be rotationally driven about rotation axis that is coaxial to the swivel axis by a seconds drive of the watch. A stop device can be actuated by the setting device and swiveling movement of the balance wheel can be blocked by the stop device.

Abstract: A winding and setting arrangement for a timepiece comprises a two-part stem extending through the hollow shaft of the spring drum. The outer part of the stem is affixed at its outer end to a crown and at its inner end has Breguet teeth which, in an inner position of the stem, are engageable with Breguet teeth of a connecting member which is non-rotatable but axially movable in a cavity in the hollow spring drum shaft. A spring urges the connecting member outwardly against a shoulder in the shaft. The inner part of the stem is coupled with the outer part by a square section so that the two parts rotate together but are axially movable relative to one another. The inner stem part passes freely through the connecting member and, inwardly of the spring drum, carries a pinion which is engageable with a setting wheel in an outer position of the stem. A spring urges the inner stem part outwardly.
