- the display mechanism disclosed in this document comprises a representation of the fixed Moon, carried by the dial of the corresponding timepiece, in front of which moves a mask carried by an arm driven so as to present a retrograde movement periodic. More precisely, the mask is driven to exhibit the following movements, during each period whose duration is equal to that of a lunar cycle: starting from a first full Moon configuration, the mask is driven in the direction of rotation counterclockwise from an initial position, to gradually cover the representation of the Moon, up to a new Moon configuration, the training continuing further up to a position final in which the representation of the Moon is again completely clear, in a new full Moon configuration. The mask is then driven quickly in the direction of clockwise rotation (i.e. a retrograde movement in reference to the slow anti-clockwise training phase) to return to its initial position, still in full Moon configuration, before to start a new cycle.

- Patent EP1692574B1 describes another mechanism for displaying the phases of the Moon meeting the characteristics mentioned above. More precisely, this mechanism includes a representation of the Moon carried by a first arm and a mask carried by a second arm. The arms are driven so as to present a first slow movement in respective opposite directions to move from a first full Moon configuration to a second full Moon configuration, gradually passing through waning Moon phases, a new Moon configuration , then phases of the waxing Moon. Once the second full Moon configuration is reached, the Moon representation and mask are quickly moved, retrogradely, back to the first full Moon configuration after a duration equal to one lunar cycle, before beginning a new cycle.
- this mechanism makes it possible to reduce the bulk of the display of the phases of the Moon given that the angular sector covered by the mask is reduced thanks to the fact that the representation of the Moon is also driven in the opposite direction to that of the mask.

- the diagram in Figure 1 has three lines arranged one above the other.
- the upper line represents the appearance of the Moon as it appears in the sky when it is located at its zenith (its orientation constantly changing perceptibly due to the rotation of the Earth on itself ), at a latitude of around 45 degrees, on the first day of a new lunar cycle starting on a new Moon, then on day 4, on day 7, on day 11, on day 15 (full Moon) , on day 19, on day 22, on day 25, then on day 29 (next new Moon).
- the next line (in the middle) represents schematic representations of the phases of the Moon at the same times throughout the lunar cycle, always while it is located at its zenith.
- the lower line represents, in a schematic and simplified manner, the implementation of a display mechanism 1 of the phases of the Moon, according to a preferred embodiment of the invention, making it possible to display the phases of the Moon in a reliable and realistic manner with reference to what can be observed in the sky when the Moon is located at its zenith.
- the configuration of the display mechanism has not been represented for all the days of the lunar cycle illustrated in the first two lines, but only on the first day, on day 7, on day 15, on day 22 and day 29.
- the display mechanism 1 comprises a Moon display member 2 carrying a representation of the Moon 4, the latter here taking the form of a rotating dial, for non-limiting purposes of illustration.
- a mask 6 is arranged above the rotating dial (from the point of view of an observer of the corresponding timepiece), so as to be able to at least partially cover the representation of the Moon 4 in certain configurations.
- the mask 6 is here carried by a frame (numerical reference 8 in Figure 4) rotated adequately to allow the phases of the Moon to be displayed at each moment.
- the mask 6 here has the shape of a disc whose diameter is equal to, or even slightly greater than, that of the representation of the Moon 4.
- Two additional discs 10 and 12, also carried by the chassis have been illustrated for non-limiting purposes.
- the disks 10 and 12 can in particular define counters in which additional information can advantageously be displayed, whatever its nature, temporal or not (the current time, the date or other calendar information, a power reserve, etc. ..).
- Those skilled in the art could, for example, implement a display mode, in relation to the discs 10, 12, such that the orientation of the display concerned is kept constant in all positions of the disc on the dial. Constructions allowing to obtain such an effect are known in the state of the art.

More precisely, it can advantageously be provided that the diameter of the representation of the Moon represents at least 50%, preferably at least 60%, of the radius of the rotary dial which carries it.
- the display mechanism 1 thus makes it possible to implement a spectacular display of the phases of the Moon, without giving up displaying other information.
- the large dimensions of the representation of Moon 4 and mask 6 have an impact on the extent of the trajectory that they both describe, which is important (it extends over a little less than half of dial in the example illustrated in Figure 1), but the training kinematics implemented makes it possible to optimize the corresponding size.
- the available surface can be used, as mentioned above, to display additional information, in particular by the use of disks 10, 12. It will be noted that the mask 6 itself can also be used to display information as described previously in relation to disks 10 and 12.

- the probe When the probe reaches the second portion of the additional mask cam 52, the latter presents an increasing radius to the additional probe, which causes a rotation of the mask rocker 54 in the counterclockwise direction on the view of Figure 4, thus causing a rotation of the frame 8, and therefore of the mask 6, in a clockwise direction.
- the elastic return member 70 accumulates mechanical energy.
- the feeler reaches the third portion of the additional mask cam 52, the elastic return member 70 can release the accumulated mechanical energy by causing the additional feeler to fall to the level of the first portion of the cam 52 of mask, by rapidly rotating the mask rocker 54 in the direction of anti-clockwise rotation in the view of Figure 4, via the crown 68 and the return 66.
- the mask 6 as well as the disks 10 and 12 can be used to implement additional displays of any type of information, time or not.

- Each of the drive mobiles 40, 62 advantageously comprises a friction between its wheel and its pinion, to allow rotation of the wheel only, when adjusting the latitude.
- the teeth of the latitude correction wheel 98 which is engaged with the lower star of the drive wheel 104 change, which causes a change in the direction of rotation of the latter.
- Such a construction allows, with adequate indexing of the mechanism, to correct the latitude over its entire range of values without changing the way of manipulating the corresponding control member, here a corrector.
- the first pulses will increase the value until it reaches 90 degrees.
- the next pulse will then decrease the latitude value and the user can thus bring it down to -90 degrees before bringing it back up by continuing to apply pressure on the corrector.
