Abstract
In this invention a watch case is attached to a support by means of an arrangement permitting separation of the case from its support whenever desired. To this effect the case includes a projection in the form of a bracket the riser of which is fastened to the case and the cross member is hollowed out to provide a spherical housing extended by two holes the diameters of which are less than that of the spherical housing. The frontal face of the cross member is provided with a slot. The support is equipped with a stem terminating in a ball. The ball is dimensioned in order that it may be forced into the spherical housing within which it may move freely with a slight amount of play. This attaching system enables coupling a pocket watch to a chain as well as a watch to a display support.
