Abstract: A device is provided for assembling a casing ring in a watch case middle including a bearing surface on an inner wall thereof, the casing ring including a housing opening in a lateral face of the casing ring, and in an upper or lower face of the casing ring. The device includes a locking part pivotable about a vertical axis of rotation passing through the upper or lower opening from a first position, in which the locking part is housed in the housing, to a second position, in which the locking part protrudes and abuts against the bearing surface of the inner wall of the case middle so as to hold the casing ring in the case middle. The locking part is snap-fitted in the housing and is pivotable about the vertical axis of rotation. A timepiece and a watch case fitted with the assembly device are also provided.

Abstract: The invention concerns a particular link structure (1) for a wristwatch including decorative elements made of hard materials such as ceramics. The sintering step carried out during manufacturing of these decorative elements increase the maximum uncertainties on their dimensions. The parts thereby obtained consequently do not have sufficiently precise dimensions to avoid the appearance of gaps at their common junctions. In order to overcome this drawback, the link (1) according to the invention includes a mechanical device (17, 26, 29, 34, 37, 53) allowing a precise adjustment to be made of the relative positions of these different decorative elements and consequently continuous junctions to be obtained between them.

Abstract: The wristband with links (2, 3, 4) includes a plurality of bars (5) acting as means for linking and articulating the links with each other and means for holding said bars in said links. Each bar is held axially by at least one of its ends (13) on to a link (2) by means of a collared sleeve (6) designed and arranged to abut against holding means (7, 8) carried both by the bar and the link.

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.
