Abstract (en)
[origin: JP2019211479A] To provide a solution to the problem with a conventional tourbillon.SOLUTION: A timepiece includes a tourbillon including a carriage 6 that bears a sprung balance 14 and a magnetic escapement device 18. The magnetic escapement device includes an escape wheel set, formed of at least one annular magnetic structure 26, and at least one magnetic element 33 coupled with the magnetic structure and having an oscillating movement that is synchronous with the oscillation of a mechanical resonator. A mechanical escapement is arranged to alternately have energy accumulation phases, from a conversion of mechanical energy supplied by a barrel into magnetic potential energy in a magnetic escapement, and transfer phases of energy accumulated in the magnetic escapement to a magnetic resonator.SELECTED DRAWING: Figure 2
