- a magnetic positioning of ten first coupling elements formed by ferromagnetic elements 15 relative to the five second coupling elements formed by tens magnets 25 is suggested. It can be seen that, for each tens and units position, the five second coupling elements formed by tens magnets 25 are in phase with 5 of the first 10 elements.

- the first reel of units 10 is stationary and shows “1”
- the first 5 magnets 15 and the second 5 magnets 25 ensure the relative positioning of the 2 indications.

- the first wheel of the units 17 with truncated teeth is arranged to rotate the first mobile display 10, the missing teeth on the first wheel 17 correspond to the absence of rotation of the first mobile display 10 when the second mobile display 20 must cover additional steps: 2 missing teeth for no rotation from 31 to 1 .
- the second tens wheel 27 with truncated teeth is arranged to drive the second mobile display 20 in rotation, the missing teeth on the second wheel 27 corresponding to the absence of rotation of the second mobile display 20 when the first mobile display 10 must travel additional steps: 27 missing teeth for rotations only the passages of days 4-5, 9-10, 19-20, 29-30 and 31 -1.

- the elastic means 3b 'At its lower surface that is to say the surface opposite that which comprises the second indicators 21.
- a reverse configuration is also applicable.
- Such a variant embodiment with purely mechanical coupling means 3′ is applicable whether the first mobile display 10 and the second mobile display 20 are coaxial as illustrated in FIGS. 3 to 5 and 10 or non-coaxial as shown in Figures 1, 2.
- Such a variant embodiment with purely mechanical coupling means 3′ is applicable whether the first mobile display 10 and the second mobile display 20 are disks or rings superimposed on one another, such as illustrated in FIG. 16 or that the first mobile display 10 and the second mobile display 20 are rollers as shown in Figure 6.
- the notches 3a 'and the elastic means 3b' are provided at their respective surfaces facing each other.
- the notches 3a' can have a rounded shape or even a V-shape.
- the elastic means 3b' can be leaf springs as illustrated in FIG. 16, or even studs, or balls, mounted on springs and configured cooperate with the notches 3a' of suitable shape.
- This invention can be applied to other displays, including and not limited to:
- the invention thus provides a good solution to the known problem of alignment in position of the elementary display mobiles combined to perform a complex display grouping together several aligned indicators.
- the invention guarantees good indexing of the displays. Described for the most common case of the combination of two display mobiles, it can also be used for more complex displays, with a greater number of display mobiles.
- the invention limits display games, which eliminates disagreeable quavering phenomena for the user.
- Roller date display mechanisms or even so-called “large window” date display mechanisms are generally composed of two separate displays for the units and the tens, and are very advantageous applications of the invention.
- Other lesser known types of displays may use the same type of display with tens and units, such as weekdays, jumping hours, and others; the invention is of course applicable for other numbers of positions on the display mobiles, for example 7, 12, or others.
- an indicator such as a zero in the nonlimiting example illustrated
- the multiplication of an indicator, such as a zero in the nonlimiting example illustrated, on a mobile display is very advantageous to allow good relative positioning of the two complementary displays.
