In a variant where it is not envisaged disassembly, the insert ring can be driven, glued, welded, riveted, crimped, or the like.

Figs. 6 and 7 illustrate a second embodiment where the axial abutment has a protruding surface at the level of the center tube 2 or a mobile that guides this center tube 2.

FIG. 6 illustrates a configuration where the mobile display is still an inner mobile 6 guided in the main bore 4 of the center tube 2. The axial stop 7 this time comprises a first protruding surface 69, which comprises the inner mobile 6, and which defines, facing the plate 3, a first abutment surface 68, which is arranged to form a stop relative to the first upper face 24 of the center tube 2.

This protruding surface may be made by deformation of the shaft of the inner mobile 6, or by material supply, or by a local deformation created by a removal of material. Without limitation, it is possible to locally push the material of the inner movable shaft 6, to form a bead, or to pre-machine this shaft with a folding lip with a rivet, or to machine, after assembly of the shaft of the inner mobile 6 already threaded into the center tube 2 and lower support, peripheral craters with a laser beam just above the end face of the center tube 2, or to perform a simple bleed of revolution, one of the lips forms the stop, or to perform a plasma projection, or welding a point or a series of points or a cord, or other.

As for the variant of FIG. 2, the inner mobile device 6 comprises, on the opposite side to the first bearing surface 66 with respect to the plate 3, a first end face 63 opposite to the first lower face 23 that comprises the center tube 2. And the relative movement of the mobile 6 inside relative to the center tube 2 is limited to the upper level by a stop abutment cooperation between the first abutment surface 68 and the first upper face 24, and, at the lower level opposite said upper level, by a bearing cooperation stop between the first end face 63 and the first lower face 23.

FIG. 7 illustrates a variant of the invention, similar to that of FIG. 6, but where the mobile display is still an outer mobile 8, guided on a main surface 5 of the center tube 2. The axial abutment 7 is a second protruding surface 28, which comprises the center tube 2, and which comprises , facing the plate 3, a second abutment surface 280 arranged to form a stop relative to a second upper face 88 that includes the outer mobile 8. This second protruding surface 28 may be made analogously to the first protruding surface 69 of fig. 6. The outer mobile 8 comprises, on the opposite side to the second upper face 88 and closest to the plate 3, a second end face 86 opposite the intermediate face 26 of the center tube 2. The relative movement of the mobile 8 outside relative to the center tube 2 is limited to the upper level by a thrust bearing cooperation between the second abutment surface 280 and the second upper face 88, and at an intermediate level between the plate 3 and the upper level by a stop abutment engagement between the second end face 86 and the intermediate face 26.

In another variant, the needle 71 is driven on a first bearing 66 of the shaft of the inner mobile 6 abutting abutment on a first shoulder 67 that includes the inner mobile 6, at one end of the first range 66. More particularly, this inner mobile 6 is a second mobile in the center. In this variant, it is the barrel 710 of the needle which abuts on the first upper face 24 of the center tube 2. It therefore controls the stroke rating, and therefore the position of the stop because the needle is driven against a shoulder.

Figs. 17 to 23 illustrate another variant, with the mounting of three concentric wheels with the board which acts as circlips, thus removing the bottom side bridge and the deck side dial. The tubes and center pins are mounted with their board riveted, then during the vertical insertion the mobiles are clipped in position. Everything then forms an indémontable whole.

More specifically, the inner mobile 6, more particularly carrying the seconds shaft, comprises a wheel having a marking opening 603, which also defines an arm 602 carrying a flexible tongue 601 arranged to cooperate by clipping with a lower groove 206 that includes the center tube 2, for its axial stop, as shown in FIGS. 18, 19 and 20.

The outer mobile 8, more particularly the minute wheel, has a similar arrangement, and comprises a wheel having a marking opening 803, which also defines an arm 802 carrying a flexible tongue 801 arranged to cooperate by clipping with a middle groove 208 that includes the center tube 2, for its axial stop, as visible in FIGS. 18, 20 and 21.

An upper mobile 80, more particularly the hour wheel, similarly to FIGS. 2 and 3, comprises a similar arrangement, and comprises a wheel having a marking opening 8003, which also delimits an arm 8002 carrying a flexible tongue 8001 arranged to cooperate by clipping with an upper groove 8000 that comprises the outer mobile 8, for its axial stop, as visible in FIGS. 18, 22 and 23.
