Abstract (en)
[origin: EP0957414A1] A ring (10) made from a tungsten alloy or the alloy and steel is thickened (12) over about 180 degrees to form an unbalanced weight (12) and is mounted on a disk (4). The disk made from sapphire or other material is transparent or translucent and is fixed to the ring by screwing or riveting, and forms the linking member. A hub (8) press fitted to the disk provides connection between the watch mechanism and the unbalanced weight (12).
