A monolithic timepiece mechanism made in a single plate of material, comprising a frame, a first elastic suspension and an inertial regulating member which is connected to the frame by the first elastic suspension so as to be able to oscillate, a blocking mechanism having a blocking member connected to the frame by a second elastic suspension. The blocking member is controlled by the regulating member to be able to regularly and alternatively hold and release a energy distribution member and to regularly transmit energy from the energy distribution member to the regulating member.

Timepiece display mechanism comprising a centre pipe fixed on a plate, this centre pipe comprising a main bore or a main guide bearing surface for receiving and guiding in rotation, about a main axis, a display wheel set internal or external to the centre pipe, and this display mechanism comprises an axial stop arranged to limit to a predetermined value the axial play in the direction of the main axis between the centre pipe and the display wheel set, and which is an added axial stop which is either captively mounted between the centre tube and the display wheel set, or fixed to the display wheel set.

An assembly of timepiece parts assembled together with an adhesive at a temperature T.sub.A and to be repositioned when the adhesive is at a temperature T.sub.C. The adhesive includes a formulation, which at T.sub.C includes a mixture of polymer chains with pendant diene units X and coupling molecules including two dienophile end groups Y, wherein the X units and the Y groups are arranged to react with one another and to bond together with the Diels-Alder reaction at a temperature T.sub.DA and to regenerate with the retro-Diels-Alder reaction at a temperature T.sub.RDA, at T.sub.A forms a three-dimensional network, in which the polymer chains are linked to one another by the coupling molecules with the Diels-Alder reaction, where T.sub.A<T.sub.RDAT.sub.C, where temperature T.sub.DA ranges between 0 C. and 100 C. and temperature T.sub.RDA ranges between 50 C. and 200 C., and T.sub.DA is strictly lower than T.sub.RDA. A process for assembling and repositioning two timepiece parts with a repositionable hot melt adhesive to enable the timepiece parts to be repositioned when the adhesive is heated.
