1. A timepiece comprising: a case,a movement housed in the case,a crystal closing the case,a dial arranged between the movement and the crystal, said dial being capable of assuming a first state in which elements situated behind the dial in reference to the crystal are visible from the side of the crystal and a second state in which said elements are hidden,a mobile portion capable of moving between at least one first and at least one second positions corresponding respectively to the first and second states of the dial, anddisplay organs arranged between the dial and the crystal,said timepiece also comprising a cover mounted mobile relative to the case and kinematically connected to said mobile portion to cause it to go from its first to its second positions and to cause the dial to go from its first to its second states. 2. The timepiece of claim 1, wherein said mobile portion is part of the dial and wherein the dial is positioned opposite at least one display zone situated between the movement and the crystal, and wherein, when the dial is in its first state, it does not allow light from the outside to enter at least in said zone, andwherein, when the dial is in its second state, it is passed through by the light coming from outside the watch toward the movement, at least in said zone. 3. The timepiece of claim 2, wherein the dial comprises a first polarized glass in a first direction and a second glass polarized in a second direction, one of the two glasses defining the mobile portion, said glasses being arranged such that, when the dial is in its first state, the directions of polarization are oriented perpendicularly and are parallel in the second state. 4. The timepiece of claim 3, wherein one of the glasses is mounted on a mobile frame kinematically connected to the cover. 5. The timepiece of claim 1, wherein said cover is capable of evolving between a first and a second extreme position, and wherein the first and second extreme positions of the cover correspond to the first and second states of the dial, respectively. 6. The timepiece of claim 2, wherein the dial includes a first prism situated on the side of the crystal of the watch and comprising a colored face and a second prism having a shape complementary to the first, at least one of said prisms defining the mobile portion so as to evolve between a first position defining the first state of the dial, in which the two prisms are distant from each other and the light coming from the outside is reflected on the colored face and sent back to the outside, anda second position defining the second state of the dial, in which the two prisms are in contact with each other, the light coming from the outside passing through them. 7. The timepiece of claim 1, also including an electrical energy source, wherein the dial includes an LCD-type cell, the dial being in its first state when said cell is powered on and in its second state when the cell is not powered on and wherein the mobile portion controls the powering on of the cell. 8. The timepiece of claim 1, wherein the dial is pierced with an opening, and wherein said mobile portion define defines a fitting dimensioned and arranged so as to be able to cover said opening. 9. The timepiece of claim 8, wherein the first and second extreme positions of the cover are defined by stops and correspond to the first and second positions of the fitting, respectively. 10. The timepiece of claim 3, wherein the mobile portion is kinematically connected to the cover by a reduction system. 11. The timepiece of claim 5, wherein the mobile portion is kinematically connected to the cover by a reduction system. 12. The timepiece of claim 10, wherein the reduction system is a differential. 13. The timepiece of claim 11, wherein the reduction system is a differential. 14. The timepiece of claim 10, wherein the cover and the frame are kinematically connected via an endless screw. 15. The timepiece of claim 11, wherein the cover and the frame are kinematically connected via an endless screw. 16. The timepiece of claim 2, wherein said cover is capable of evolving between a first and a second extreme position, and wherein the first and second extreme positions of the cover correspond to the first and second states of the dial, respectively. 17. The timepiece of claim 3, wherein said cover is capable of evolving between a first and a second extreme position, and wherein the first and second extreme positions of the cover correspond to the first and second states of the dial, respectively. 18. The timepiece of claim 4, wherein said cover is capable of evolving between a first and a second extreme position, and wherein the first and second extreme positions of the cover correspond to the first and second states of the dial, respectively. 19. The timepiece of claim 4, wherein the mobile portion is kinematically connected to the cover by a reduction system. 20. The timepiece of claim 8, wherein the mobile portion is kinematically connected to the cover by a reduction system. 21. The timepiece of claim 9, wherein the mobile portion is kinematically connected to the cover by a reduction system.
