The present invention concerns a mechanical watch ( 1 ), preferably of the pocket watch type, wound by a key. More specifically, the present invention concerns a protective device for the aperture ( 6 ) allowing access to the winding mechanism of such a watch, particular to the winding stem ( 7 ). For this purpose, a moving element ( 8 ) is implemented, mounted around the stem ( 7 ) and able to move between two end positions, first of all to at least partially block the aperture ( 6 ) in normal use and, secondly, to release access to the winding stem ( 7 ) in order to wind the watch.
