Abstract
The main element 2 is connected to the mechanism of the movement, having parts 4, 5, by an arbor about which it can turn. To this end, it comprises an attachment 6 for fixing to the movement, which is for example formed by a small ring arranged in the opening 9 of the ring of the main element 2. The attachment 6 is thus composed of the same material as the main element and is arranged in the same plane. By virtue of the attachment 6, the winding mass can make a circular movement about the arbor, when it oscillates.
