6. The display device as claimed in claim 1 , wherein the third and fourth toothsets complement one another and together form at least one of:

a sixth toothset having thirty-one or thirty teeth, and

a toothset having an angular pitch of one thirty-first of a revolution.

7. The display device as claimed in claim 1 , wherein the control mobile is arranged so as to make a thirty-first of a revolution every twenty-four hours.

8. The display device as claimed in claim 1 , wherein the control mobile is at least one of (i) of one piece, (ii) manufactured as one, and (iii) created by assembly of two elements respectively having the third and fourth toothsets.

9. The display device as claimed in claim 1 , wherein at least one of (i) the third and fourth toothsets are external toothsets, and (ii) the fifth toothset is an external toothset.

10. The display device as claimed in claim 1 , wherein at least one of (i) the first and second disks are arranged on one and the same plane, (ii) the first and second disks each have the same number of numerals, and (iii) the first and second disks have substantially the same diameter.

11. The display device as claimed in claim 1 , wherein at least one of (i) the third toothset comprises thirty teeth, the angular pitch between the teeth being 360°/31, and (ii) the fourth toothset comprises four teeth or five teeth, the angular pitch between two teeth being a multiple of 360°/31.

12. The display device as claimed in claim 1 , wherein an angle formed by (i) a first semistraight line having an origin on an axis of rotation of the control mobile and passing through an axis of rotation of the first mobile, and (ii) a second semistraight line having an origin on the axis of rotation of the control mobile and passing through an axis of rotation of the second mobile, is less than 170°.

13. The display device as claimed in claim 1 , wherein at least one of (i) the drive wheel is secured to a star, and (ii) the drive wheel is situated at the center of a timepiece movement.

14. The display device as claimed in claim 1 , wherein the second disk comprises one of the following series of numerals:

“0, 1, 2, 3, 0, 1, 2, 3”;

“0, 0, 1, 2, 3, 0, 0, 1, 2, 3”;

“0, 1, 1, 2, 3, 0, 1, 1, 2, 3”;

“0, 1, 2, 2, 3, 0, 1, 2, 2, 3”;

“0, 1, 2, 3, 3, 0, 1, 2, 3, 3”.

15. The display device as claimed in claim 1 , comprising at least one of:

(i) a first jumper associated with the first mobile, the first jumper and the first mobile being arranged so as to position the first mobile in a next position before the first mobile has covered half an angular pitch in a direction of increasing indication of the numerals borne by the first disk,

(ii) a second jumper associated with the second mobile, the second jumper and the second mobile being arranged so as to position the second mobile in a next position before the second mobile has covered half an angular pitch in a direction of increasing indication of the numerals borne by the second disk,

(iii) a first jumper associated with the first mobile, the first jumper and the first mobile being arranged so as to position the control mobile in a next position after the control mobile has covered half an angular pitch, and

(iv) a second jumper associated with the second mobile, the second jumper and the second mobile being arranged so as to position the control mobile in a next angular position after the control mobile has covered half an angular pitch.
