1. A device (100) for temporarily stopping the operation of a mechanical watch (1), the device comprising at least three levers (4) assembled and disposed in a circle on a plate (50) of a mechanical horological movement, at least one action member (2) of the levers (4) to switch the levers (4) together from a rest mode to an active mode to act directly on a stop lever (17) of the device, which is arranged to temporarily stop an oscillator (14) of the mechanical horological movement, the activation of the stop lever (17) being able to be carried out by at least one of the levers (4) regardless of the position of the stop lever (17), wherein the levers (4) are arranged on the plate (50) so that in the active mode, the levers (4) define a continuous circular peripheral edge to activate the stop lever (17) in any position of a tourbillon cage (15).
