Abstract
Control device for a watch movement having a part rotatably movable around an axis A. The device is associated with a watch case (11) and has a lock (25) actuatable from outside the watch. The lock is movably mounted in translation to the periphery of the watch case (11). The device also has a movably mounted plate (30) which is rotatable around an axis D inside the watch case and is kinematically connected to the lock. An arm (34) is pivotable around and axis B, whose first end is placed on the plate in such a way that it is freely rotatable around an axis C non-merging with the axis D and whose other end is fixed to the part for driving the movement.
Claims12
A watch mechanism control device comprising a component rotatable about a first axis, said device being designed to be fitted to a watch case and comprising a push-piece actuatable from the outside of the watch,
- wherein said push-piece can be moved translationally along the periphery of said case and in that it also includes, housed in the watch case:
- a plate mounted, rotatably about a second axis, inside said case, and connected kinematically to said push-piece, and
- an arm hinged about a third axis, with one end arranged over said plate and free to rotate about a fourth axis that does not coincide with said second axis, and the other end fixed to said component for actuating the mechanism.
