Abstract (en)
[origin: JP2020091282A] To provide a timepiece movement that simplifies a regulating member in a timepiece tourbillon.SOLUTION: A timepiece tourbillon comprises a carriage 1 mounted pivotally about a tourbillon axis DT with respect to a structure and carrying a balance 2 pivoting about a balance axis DB. The balance is arranged to cooperate in a reciprocating motion with a stop device 3 mounted pivotally on the carriage. The tourbillon includes a fixed magnetic wheel fixed to the structure, the fixed magnetic wheel comprising at least one continuous magnetic track and/or a series of magnets. The magnetic track is arranged to cooperate by magnetic repulsion and/or attraction with at least one magnet included in the stop device in a reciprocating motion of the stop device with respect to the fixed magnetic wheel.SELECTED DRAWING: Figure 7
