Abstract: The invention concerns an identification tag consisting of a first (10) and a second plate (12) one of which (12) is provided with a rod (24) having a perforating and retaining head (32), defining a first axis, to form a male element and the other (10) comprises an orifice (26) for receiving and maintaining the head (32) of the rod (24) and constituting a female element. The invention is characterized in that the plates (12) are linked to each other articulated about a second axis, with a hinge (14) formed by: at least a knuckle (16), secured to the first plate (10), a pivot (18) coaxial with and engaged in the knuckle (16) and an elastic member arranged so as to be deformed when a force exceeding a threshold value is applied, thereby enabling the pivot (18) to be released from the knuckle (16).

Abstract: An element made of elastomeric material (9) is made by overmoulding between the middle part (2) of a watch case and a support ring, in particular a casing ring (3) intended to support the watch movement. This allows the constraints of the inner form and inner machining of the middle part to be reduced, while allowing accurate positioning of the internal elements of the watch with respect to the middle part. The elastomeric element (9) can also assure sealing with the control stem and/or the crystal of the watch.
