The invention concerns a particular link structure ( ) 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 ( ) according to the invention includes a mechanical device ( ) 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.

Link for watch bracelet

The wristband with links ( ) includes a plurality of bars ( ) 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 ( ) on to a link ( ) by means of a collared sleeve ( ) designed and arranged to abut against holding means ( ) carried both by the bar and the link.

Wristband with articulated links

A wristband ( ) with articulated links preferably made of injected ceramics includes per assembly pitch two lateral links ( ) each including a threaded hole ( ) and a smooth hole ( ), a central link ( ) pierced with two smooth through holes ( ), a bar ( ) threaded at least at its ends and a spring bar ( ).

An element made of elastomeric material (,) is made by overmoulding between the middle part (,) of a watch case and a support ring, in particular a casing ring (,) 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 (,) can also assure sealing with the control stem and/or the crystal of the watch.
