Abstract
A sealing device for a minute-repeater mechanism, comprising a striking work control bolt which can move in an aperture of a case between a rest position and a pulled-out position. The case includes a seat for receiving in sealed abutment, in the rest position of the bolt, a first sealing gasket mounted in a sealed manner on the bolt and moveable therewith, and which is at a distance from the seat when the bolt is in a pulled-out position for operating the striking work. The case includes a chamber, one wall of which comprises the aperture, which limits the travel of a second sliding sealing gasket in which the bolt slides in a sealed manner, and which is in sealed abutment on an inner surface of the chamber.

A sealing device for a minute-repeater mechanism for a timepiece, comprising:
- a striking work control bolt which can move in a case between a rest position and at least one pulled-out position, said bolt being guided in at least one aperture of said case and wherein said case includes a seat for receiving in sealed abutment, when said bolt is in said rest position, at least one first sealing gasket which is static with respect to the bolt and mounted in a sealed manner on said bolt and moveable therewith, and wherein said first sealing gasket is at a distance from said seat when said bolt is in said pulled-out position, for operating the striking work, wherein said bolt includes an abutment surface, which pushes said first sealing gasket, and compresses said first sealing gasket onto said seat when said bolt is in said rest position, under the action of an elastic return means comprised in said device which exerts stress on said bolt tending to return said bolt to the rest position thereof.
