An electronic tourbillion clock including a clock case having a plurality of high-resolution digital displays that extend around an outer circumference of the clock case as an indicator of hours. A seven segment display is located within the clock case as an indicator of minutes elapsed within an hour. A microcontroller determines the current time and other chronological indications depending on the output signals generated by a position of a tourbillon mechanism disposed in the clock case. A sub-circuit is disposed within the clock case and interconnected with the microcontroller for creating a plurality of distinctive sound patterns directed through one or more speakers in response to the output signals generated by the position of the tourbillon mechanism.

The timepiece includes a tourbillon including a carriage that bears a sprung balance and a magnetic escapement device, the latter including an escape wheel set, formed of an annular magnetic structure, and a magnetic element coupled with the magnetic structure and having an oscillating movement that is synchronous with the oscillation of the mechanical resonator. The mechanical escapement is arranged so as to have alternately energy accumulation phases, from a conversion of mechanical energy supplied by the barrel into magnetic potential energy in the magnetic escapement, and transfer phases of energy accumulated in the magnetic escapement to the magnetic resonator. During the energy transfer phases, the magnetic element is subjected to a magnetic force such that the magnetic escapement then converts into mechanical energy magnetic potential energy accumulated in the preceding energy accumulation phase to be able to maintain the oscillation of the mechanical resonator.

A tourbillon (1) with a rotation cage which is rotatably arranged about a tourbillon axis is provided. The rotation cage mounts a balance wheel (3) and an escapement with an escape wheel (8) and a lever. The tourbillon is characterised in that the rotation cage comprises a bearing wheel (22) which is mounted by bearing elements (13) which engage peripherally on a running surface (11) of the bearing wheel (22).

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.
