The invention relates to a screw-down orientable crown comprising a cover integral with a tube and receiving a distinctive sign, a fixed body pressed into a watch case middle and intended to receive the tube, and means for adjusting the angular orientation of the cover with respect to the case middle. According to the invention, the means for adjusting the angular orientation of the cover comprise a ring arranged to be screwed onto the tube, said ring comprising first indexing means arranged to cooperate with second indexing means formed in the body, the ring being pressed in and positioned on the body via the first and second indexing means.

Screw-down orientable crown

A crown for timepieces which has improved sealing regardless of its position. To achieve this, the crown includes a tube; a cap including a cover and an axial skirt; a sealing gasket disposed between the screwed or pressed-in tube and the axial skirt of the cap; a pipe fixed to the cap, the pipe and the cap forming an assembly able to be placed in different axial positions relative to the screwed or pressed-in tube; wherein the crown further includes a guide ring integral with one end of the screwed or pressed-in tube, the guide ring including a bearing surface arranged to exert an axial pressure on the sealing gasket in one of the axial positions of the cap.

Setting crown for timepieces

Method for the modular assembly of a pusher to a watch case () including a preliminary step of assembling a sealed functional module (), including a tube (), a stem (), at least one sealing gasket () and a return spring () arranged between a first fixed stop member and a second moveable stop member, and then a first step (E) of assembling the sealed functional module () to the case (), and finally a second step (E) of assembling a pusher head () to the sealed functional module ().
