Description

Domaine techniqueTechnical field

La présente demande concerne le domaine de l'horlogerie et plus particulièrement la représentation des phases de Lune. De préférence, la présente invention se rapporte à une représentation fidèle des phases de Lune en fonction de certains paramètres et/ou à la demande de l'utilisateur.The present application relates to the field of watchmaking and more particularly to the representation of the phases of the Moon. Preferably, the present invention relates to a faithful representation of the phases of the Moon as a function of certain parameters and/or at the request of the user.

Arrière-plan technologiqueTechnological background

La plupart des indicateurs de phases de Lune utilise un élément sur lequel est représenté deux Lunes entières tournant sous un masque et apparaissant dans un guichet. La position angulaire des Lunes tournant par rapport au masque et au guichet tente de simuler l'aspect de la phase de Lune vu dans le ciel. Ce mécanisme n'en donne qu'une représentation grossière, surtout pour les phases de croissance et de décroissance respectivement après et avant la demi-Lune.Most Moon phase indicators use a component that shows two full Moons rotating under a mask and appearing in an aperture. The angular position of the rotating Moons relative to the mask and aperture attempts to simulate the appearance of the Moon phase as seen in the sky. This mechanism only gives a rough representation, especially for the waxing and waning phases after and before the half Moon respectively.

De plus, au cours du temps, la courbure de la face claire de la lune reste constante sur ces indicateurs de phases de Lune, en l'espèce convexe au-delà du premier quartier par exemple, au lieu de devenir concave comme cela est observable en réalité.Furthermore, over time, the curvature of the light side of the moon remains constant on these moon phase indicators, in this case convex beyond the first quarter for example, instead of becoming concave as is observable in reality.

Plusieurs modèles proposent un autre concept qui consiste à représenter sur un cadran différentes phases de Lune et à utiliser une aiguille rétrograde pour indiquer la phase de Lune. Il apparaît cependant que les représentations des phases de Lune sont statiques et très grossières car il n'y a que 3 ou 4 représentations pour illustrer les 28 phases de Lune environ.Several models propose another concept which consists of representing on a dial different phases of the Moon and using a retrograde hand to indicate the phase of the Moon. It appears however that the representations of the phases of the Moon are static and very crude since there are only 3 or 4 representations to illustrate the approximately 28 phases of the Moon.

Le document EP1615086A1 divulgue une pièce d'horlogerie avec un affichage des phases de lune, dans laquelle un disque de lune rotatif comporte plusieurs représentations des phases de lune. L'affichage s'effectue au travers d'un guichet fixe.The document EP1615086A1 discloses a timepiece with a moon phase display, in which a rotating moon disk has multiple representations of the moon phases. The display is made through a fixed aperture.

Dans le document GB2454905A le disque portant les représentation des phases de lune est fixe, alors qu'un guichet rotatif pivote ci-dessus. Il est également prévu un mode de réalisation dans lequel le disque de lune et le guichet sont rotatifs et pivotent l'un vers l'autre pour laisser apparaître la juste indication de phase de lune.In the document GB2454905A the disk bearing the moon phase representations is fixed, while a rotatable aperture pivots above. Also provided is an embodiment in which the moon disk and the aperture are rotatable and pivot towards each other to reveal the correct moon phase indication.

Par ailleurs, il semblerait que le phénomène de libration soit totalement absent dans ces représentations, ce que déplore une grande majorité d'amateurs.Furthermore, it would seem that the phenomenon of libration is totally absent in these representations, which is deplored by a large majority of enthusiasts.

Description détaillée de l'inventionDetailed description of the invention

Il existe des montres comportant des indicateurs de phases de Lune avec un élément sur lequel est représenté deux Lunes entières tournant sous un masque et apparaissant dans un guichet de manière grossière sans être fidèle dans les phases de croissance et de décroissance, ni pour les zones visibles depuis la Terre, et ce peu importe la position de l'observateur sur le globe.There are watches with moon phase indicators with an element on which are represented two whole moons rotating under a mask and appearing in a window in a crude manner without being faithful in the phases of growth and waning, nor for the areas visible from the Earth, and this regardless of the position of the observer on the globe.

La présente invention permet de représenter différentes phases de Lune reproduisant le plus fidèlement possible l'image de la Lune dans le ciel, dans l'hémisphère Nord ou dans l'hémisphère Sud, ainsi que l'évolution des structures éclairées et la surface visible.The present invention makes it possible to represent different phases of the Moon reproducing as faithfully as possible the image of the Moon in the sky, in the Northern hemisphere or in the Southern hemisphere, as well as the evolution of the illuminated structures and the visible surface.

En effet, la présente invention peut concerner une montre comprenant un dispositif d'affichage 100 pour pièce d'horlogerie et de préférence de pièce d'horlogerie. Ledit dispositif d'affichage 100 est configuré pour afficher un ensemble de représentation de phases de Lune 115 reproduisant l'image de la Lune dans le ciel, et est configuré pour fonctionner selon au moins un mode de fonctionnement parmi au moins un premier mode de fonctionnement primaire 150, au moins un deuxième mode de fonctionnement primaire 159, au moins un premier mode de fonctionnement secondaire 160 et/ou au moins un deuxième mode de fonctionnement secondaire 169. Indeed, the present invention may relate to a watch comprising a display device 100 for a timepiece and preferably a timepiece. Said display device 100 is configured to display a set of Moon phase representations 115 reproducing the image of the Moon in the sky, and is configured to operate according to at least one operating mode among at least a first primary operating mode 150, at least a second primary operating mode 159, at least a first secondary operating mode 160 and/or at least a second secondary operating mode 169.

Une permutation entre au moins un premier mode de fonctionnement primaire 150, au moins un deuxième mode de fonctionnement primaire 159, au moins un premier mode de fonctionnement secondaire 160 et/ou au moins un deuxième mode de fonctionnement secondaire 169 est permise grâce à un organe de permutation configuré pour permuter entre au moins un premier mode de fonctionnement primaire 150, au moins un deuxième mode de fonctionnement primaire 159, au moins un premier mode de fonctionnement secondaire 160 et/ou au moins un deuxième mode de fonctionnement secondaire 169, de sorte que l'utilisateur puisse permuter entre au moins un premier mode de fonctionnement primaire 150, au moins un deuxième mode de fonctionnement primaire 159, au moins un premier mode de fonctionnement secondaire 160 et/ou au moins un deuxième mode de fonctionnement secondaire 169. A permutation between at least a first primary operating mode 150, at least a second primary operating mode 159, at least one first secondary operating mode 160 and/or at least one second secondary operating mode 169 is enabled by means of a switching member configured to switch between at least one first primary operating mode 150, at least one second primary operating mode 159, at least one first secondary operating mode 160 and/or at least one second secondary operating mode 169, such that the user can switch between at least one first primary operating mode 150, at least one second primary operating mode 159, at least one first secondary operating mode 160 and/or at least one second secondary operating mode 169.

Ledit dispositif d'affichage 100 peut comprendre au moins un mobile de Lune 110, au moins un guichet 120 et au moins un organe d'entraînement 130 configuré pour déplacer ledit au moins un mobile de Lune 110 et/ou pour déplacer ledit au moins un guichet 120. Said display device 100 may comprise at least one moon mobile 110, at least one window 120 and at least one drive member 130 configured to move said at least one moon mobile 110 and/or to move said at least one window 120.

Ledit au moins un mobile de Lune 110, visible sur la figure 1, peut comprendre ledit ensemble de représentation de phases de Lune 115 mentionné ci-avant. Ledit ensemble de représentation de phases de Lune 115 comporte au moins trois phases de Lune et chaque phase de Lune 116 desdites au moins trois phases de Lune est configurée pour présenter une première surface 118, une deuxième surface 119 et/ou une délimitation 117 configurée pour délimiter ladite première surface 118 et ladite deuxième surface 119. Ladite première surface 118 et/ou ladite deuxième surface 119 comprend ou comprennent au moins un effet relief tel un cratère lunaire, et ce, soit imprimé en 3D ou microstructuré soit imprimé en 2D avec des nuances de couleurs de sorte à mieux représenter la Lune.Said at least one Moon 110 mobile, visible on the figure 1 , may comprise said Moon phase representation set 115 mentioned above. Said Moon phase representation set 115 comprises at least three Moon phases and each Moon phase 116 of said at least three Moon phases is configured to have a first surface 118, a second surface 119 and/or a delimitation 117 configured to delimit said first surface 118 and said second surface 119. Said first surface 118 and/or said second surface 119 comprises or comprises at least one relief effect such as a lunar crater, and this, either printed in 3D or microstructured or printed in 2D with shades of colors so as to better represent the Moon.

Ladite délimitation 117 peut être absente ou se confondre avec la courbure de la représentation de Lune lors de la pleine Lune et/ou lors de la nouvelle Lune. Ainsi, ladite délimitation 117 comprend un rayon de courbure, de préférence ladite délimitation 117 de chaque phase de Lune 116 desdites au moins trois phases comprend un rayon de courbure distinct de sorte que chaque phase de Lune 116 desdites au moins trois phases reproduise le plus fidèlement possible l'image de la phase correspondante.Said delimitation 117 may be absent or merge with the curvature of the Moon representation during the full Moon and/or during the new Moon. Thus, said delimitation 117 comprises a radius of curvature, preferably said delimitation 117 of each Moon phase 116 of said at least three phases comprises a distinct radius of curvature such that each Moon phase 116 of said at least three phases reproduces as faithfully as possible the image of the corresponding phase.

Selon les modes de réalisation, ladite première surface 118 peut être plus transparente ou plus translucide que ladite deuxième surface 119, et/ou ladite première surface 118 peut être plus claire que ladite deuxième surface 119. Par ailleurs, selon les variantes, ladite première surface 118 peut être une ouverture dans ledit au moins un mobile de Lune 110, être transparente ou être translucide et/ou ladite deuxième surface 119 peut être opaque ou être translucide. Dans ces modes de réalisations, ledit dispositif d'affichage 100 peut comprendre une représentation de Lune configurée pour apparaître dans ladite ouverture, à travers ladite première surface 118 et/ou à travers ladite deuxième surface 119. Ladite représentation de Lune peut être statique et peut se trouver sur une partie de ladite montre, de préférence, sur une portion du cadran de ladite montre.According to the embodiments, said first surface 118 may be more transparent or more translucent than said second surface 119, and/or said first surface 118 may be lighter than said second surface 119. Furthermore, according to the variants, said first surface 118 may be an opening in said at least one Moon mobile 110, be transparent or be translucent and/or said second surface 119 may be opaque or be translucent. In these embodiments, said display device 100 may comprise a Moon representation configured to appear in said opening, through said first surface 118 and/or through said second surface 119. Said Moon representation may be static and may be on a part of said watch, preferably, on a portion of the dial of said watch.

Par ailleurs, ledit dispositif d'affichage 100 peut comprendre au moins une source de lumière 140 configurée pour illuminer, de préférence à travers, ladite première surface 118 et/ou ladite deuxième surface 119 et sur laquelle, c'est-à-dire sur ladite au moins une source de lumière 140, peut se trouver ladite représentation de Lune. Ainsi, avantageusement, ladite première surface 118, qu'elle soit ouverte, transparente ou translucide permet de laisser passer plus facilement la lumière que ladite deuxième surface 119, qui est plutôt opaque ou moins translucide, de sorte que les différentes phases de Lune reproduisent le plus fidèlement possible l'image de la Lune dans l'obscurité. Il est également possible de remplacer ladite au moins une source de lumière 140 par une surface réfléchissante, comme par exemple un miroir, une surface diffuse blanche et/ou une pierre brillante afin d'obtenir le même résultat.Furthermore, said display device 100 may comprise at least one light source 140 configured to illuminate, preferably through, said first surface 118 and/or said second surface 119 and on which, i.e. on said at least one light source 140, said representation of the Moon may be located. Thus, advantageously, said first surface 118, whether open, transparent or translucent, allows light to pass through more easily than said second surface 119, which is rather opaque or less translucent, so that the different phases of the Moon reproduce the image of the Moon in the dark as faithfully as possible. It is also possible to replace said at least one light source 140 with a reflective surface, such as for example a mirror, a white diffuse surface and/or a shiny stone in order to obtain the same result.

Il convient de noter que bien que ladite première surface 118 puisse être ouverte, transparente ou translucide, ces variantes ne peuvent être considérées comme étant équivalentes puisqu'une ouverture peut présenter des avantages qu'une surface transparente ou translucide ne peut offrir. En effet, il est possible, grâce à un laser, d'opérer une ouverture dans ladite deuxième surface 119 de sorte à créer ladite première surface 118 ainsi que ladite délimitation 117, et à éviter des problèmes d'alignement avec ladite au moins une source de lumière 140, qui peut être disposée sur tout le pourtour dudit au moins un mobile de Lune 110 comme par exemple dans les deuxième et troisième modes de réalisation, d'une part et d'autre part, alors que ladite deuxième surface 119 peut limiter de plus en plus le passage des rayons lumineux de ladite au moins une source de lumière 140, avec le temps, ladite première surface 118, c'est-à-dire ladite ouverture, restera inchangée et donc représentera, au fil du temps, les différentes phases de Lune en reproduisant le plus fidèlement possible l'image de la Lune dans le ciel. C'est le cas par exemple, lorsque l'image de la Lune est imprimée sur ladite au moins une source de lumière 140 et que ladite deuxième surface 119 vient cacher tout ou en partie l'image de la Lune imprimée sur ladite au moins une source de lumière 140, et ladite ouverture, bien que constante donc restera inchangée, laissera apparaitre la partie lumineuse de la représentation de Lune, c'est-à-dire ladite première surface 118 qui évoluera avec le temps.It should be noted that although said first surface 118 may be open, transparent or translucent, these variants cannot be considered to be equivalent since an opening can have advantages that a transparent or translucent surface cannot offer. Indeed, it is possible, by means of a laser, to operate an opening in said second surface 119 so as to create said first surface 118 as well as said delimitation 117, and to avoid problems of alignment with said at least one light source 140, which can be arranged around the entire periphery of said at least one Moon mobile 110 as for example in the second and third embodiments, on the one hand and on the other hand, while said second surface 119 can increasingly limit the passage of light rays from said at least one light source 140, over time, said first surface 118, that is to say said opening, will remain unchanged and therefore will represent, over time, the different phases of the Moon by reproducing as faithfully as possible the image of the Moon in the sky. This is the case, for example, when the image of the Moon is printed on said at least one light source 140 and said second surface 119 hides all or part of the image of the Moon printed on said at least one light source 140, and said aperture, although constant and therefore remains unchanged, will allow the luminous part of the representation of the Moon to appear, i.e. said first surface 118 which will change over time.

Selon d'autres variantes, ladite première surface 118 peut être fermée, ou pleine en opposition à ouverte, et peut comprendre un matériau brillant, réfléchissant, luminescent, photoluminescent, et/ou en sulfate de baryum. Il convient de garder à l'esprit qu'il n'est pas exclu que ladite deuxième surface 119 puisse être en matériau opaque ou translucide tout en étant recouverte totalement ou partiellement d'un matériau opaque, photo-absorbant, et/ou en carbone et/ou en nanotubes de carbone.According to other variants, said first surface 118 may be closed, or solid as opposed to open, and may comprise a shiny, reflective, luminescent, photoluminescent, and/or barium sulfate material. It should be kept in mind that it is not excluded that said second surface 119 may be made of opaque or translucent material while being totally or partially covered with an opaque, photo-absorbent, and/or carbon and/or carbon nanotube material.

L'observateur attentif remarquera que ledit ensemble de représentation de phases de Lune 115, illustré dans la présente demande, peut comprendre au moins quatre phases de Lune et jusqu'à vingt-neuf, voire trente, phases de Lune et peut ainsi représenter les phases de la Lune le plus finement possible. Pour ce faire, ladite première surface 118 et ladite deuxième surface 119, de préférence en collaboration avec ladite délimitation 117, présentent pour chaque phase de Lune différentes parties de la surface de la Lune observable dans le ciel et ce à chaque phase.The attentive observer will notice that said set of Moon phase representations 115, illustrated in the present application, can comprise at least four Moon phases and up to twenty-nine, or even thirty, Moon phases and can thus represent the phases of the Moon as finely as possible. To do this, said first surface 118 and said second surface 119, preferably in collaboration with said delimitation 117, present for each Moon phase different parts of the surface of the Moon observable in the sky and this at each phase.

Par ailleurs, ledit au moins un mobile de Lune 110 est configuré pour être mobile selon un premier axe 111 entre au moins une première position primaire 151 et au moins une deuxième position primaire 152 dans ledit au moins un premier mode de fonctionnement primaire 150 de sorte que ledit ensemble de représentation de phases de Lune 115 puisse représenter la Lune dans différents hémisphères en fonction du mode de fonctionnement.Furthermore, said at least one Moon mobile 110 is configured to be movable along a first axis 111 between at least one first primary position 151 and at least one second primary position 152 in said at least one first primary operating mode 150 so that said Moon phase representation assembly 115 can represent the Moon in different hemispheres depending on the operating mode.

Ledit au moins un guichet 120, quant à lui, est configuré pour laisser apparaître ledit ensemble de représentation de phases de Lune 115, de préférence une phase de Lune 116 desdites au moins trois phases de Lune, et est configuré pour être mobile selon un deuxième axe 121 entre au moins une première position secondaire 161 et au moins une deuxième position secondaire 162 dans ledit au moins un premier mode de fonctionnement secondaire 160. Il est à noter que ledit premier axe 111 et ledit deuxième axe 121 peuvent être coaxiaux ou distincts.Said at least one window 120, for its part, is configured to reveal said set of Moon phase representations 115, preferably one Moon phase 116 of said at least three Moon phases, and is configured to be movable along a second axis 121 between at least one first secondary position 161 and at least one second secondary position 162 in said at least one first secondary operating mode 160. It should be noted that said first axis 111 and said second axis 121 may be coaxial or distinct.

Comme susmentionné, ledit au moins un organe d'entraînement 130, représenté sur les figures 1 et 2, peut déplacer selon un premier sens primaire 155 ledit au moins un mobile de Lune 110 de ladite au moins une première position primaire 151 vers ladite au moins une deuxième position primaire 152 dans ledit au moins un premier mode de fonctionnement primaire 150 et/ou peut déplacer selon un deuxième sens primaire 156, qui peut être contraire audit un premier sens primaire 155, ledit au moins un mobile de Lune 110 de ladite au moins une deuxième position primaire 152 vers ladite au moins une première position primaire 151 dans ledit au moins un premier mode de fonctionnement primaire 150. As mentioned above, said at least one drive member 130, shown in the Figures 1 and 2 , can move in a first primary direction 155 said at least one Moon mobile 110 from said at least one first primary position 151 to said at least one second primary position 152 in said at least one first primary operating mode 150 and/or can move in a second primary direction 156, which can be opposite to said first primary direction 155, said at least one Moon mobile 110 from said at least one second primary position 152 to said at least one first primary position 151 in said at least one first primary operating mode 150.

De façon tout à fait similaire, ledit au moins un organe d'entraînement 130 peut également déplacer selon un premier sens secondaire 165 ledit au moins un guichet 120 de ladite au moins une première position secondaire 161 vers ladite au moins une deuxième position secondaire 162 dans ledit au moins un premier mode de fonctionnement secondaire 160 et/ou peut déplacer selon un deuxième sens secondaire 166, qui peut être contraire audit un premier sens secondaire 165, ledit au moins un guichet 120 de ladite au moins une deuxième position secondaire 162 vers ladite au moins une première position secondaire 161 dans ledit au moins un premier mode de fonctionnement secondaire 160. Dans les modes de réalisation où ledit premier axe 111 et ledit deuxième axe 121 sont distincts, ledit au moins un organe d'entraînement 130 peut être placé entre ledit au moins un guichet 120 et ledit au moins un mobile de Lune 110 et un système d'engrenage pouvant se débrayer, bien connu de l'homme du métier, permet de déplacer ledit au moins un mobile de Lune 110 selon ledit premier axe 111 , de préférence en rotation autour dudit premier axe 111, et/ou de déplacer ledit guichet 120 selon ledit deuxième axe 121, de préférence en rotation autour dudit deuxième axe 121. Une alternative à ce mode de réalisation peut prévoir deux organes d'entraînement 130, de sorte que ledit au moins un mobile de Lune 110 et ledit au moins un guichet 120 soient déplacés indépendamment.In a completely similar manner, said at least one drive member 130 can also move in a first secondary direction 165 said at least one aperture 120 from said at least one first secondary position 161 to said at least one second secondary position 162 in said at least one first secondary operating mode 160 and/or can move in a second secondary direction 166, which can be opposite to said first secondary direction 165, said at least one aperture 120 from said at least one second secondary position 162 to said at least one first secondary position 161 in said at least one first secondary operating mode 160. In the embodiments where said first axis 111 and said second axis 121 are distinct, said at least one drive member 130 can be placed between said at least one aperture 120 and said at least one moon mobile 110 and a disengageable gear system, well known to those skilled in the art, allows said at least one moon mobile 110 to be moved along said first axis 111 , preferably in rotation around said first axis 111, and/or to move said window 120 along said second axis 121, preferably in rotation around said second axis 121. An alternative to this embodiment may provide two drive members 130, so that said at least one moon mobile 110 and said at least one window 120 are moved independently.

Comme mentionné en amont, ledit dispositif d'affichage 100 peut être configuré pour fonctionner selon ledit au moins un deuxième mode de fonctionnement primaire 159 et/ou selon ledit au moins un deuxième mode de fonctionnement secondaire 169. Comme cela est visible sur les figures 4A et 4B, ledit au moins un mobile de Lune 110 est immobile dans ledit au moins un deuxième mode de fonctionnement primaire 159, alors que c'est ledit au moins un guichet 120 qui est immobile dans ledit au moins un deuxième mode de fonctionnement secondaire 169, figures 5A et 5B.As mentioned upstream, said display device 100 can be configured to operate according to said at least one second primary operating mode 159 and/or according to said at least one second secondary operating mode 169. As can be seen in the Figures 4A and 4B , said at least one Moon mobile 110 is stationary in said at least one second primary operating mode 159, while it is said at least one window 120 which is stationary in said at least one second secondary operating mode 169, Figures 5A and 5B .

Comme cela est illustré sur les figures 6A et 6B, les sens de mobilité 155, 156, 165 ,165 dudit au moins un mobile de Lune 110 et dudit au moins un guichet 120 dans ledit au moins un premier mode de fonctionnement primaire 150 et/ou dans ledit au moins un premier mode de fonctionnement secondaire 160 peuvent être respectés dans le troisième mode de réalisation, puisque ledit au moins un mobile de Lune 110 et ledit au moins un guichet 120 peuvent être mobiles simultanément ou indépendamment, de sorte que les différentes phases de Lune reproduisent l'image de la Lune dans le ciel dans l'hémisphère Nord et/ou dans l'hémisphère Sud.As illustrated in the Figures 6A and 6B , the directions of mobility 155, 156, 165, 165 of said at least one Moon mobile 110 and said at least one window 120 in said at least one first primary operating mode 150 and/or in said at least one first secondary operating mode 160 can be respected in the third embodiment, since said at least one Moon mobile 110 and said at least one window 120 can be movable simultaneously or independently, so that the different phases of the Moon reproduce the image of the Moon in the sky in the Northern hemisphere and/or in the Southern hemisphere.

Cette mobilité dudit au moins un mobile de Lune 110 et/ou dudit au moins un guichet 120 peut être commandée par au moins une unité de commande permettant le déplacement dudit au moins un mobile de Lune 110 entre ladite au moins une première position primaire 151 et ladite au moins une deuxième position primaire 152 via ledit au moins un organe d'entraînement 130 dans ledit au moins un premier mode de fonctionnement primaire 150 et/ou dudit au moins un guichet 120 entre ladite au moins une première position secondaire 161 et ladite au moins une deuxième position secondaire 162 via ledit au moins un organe d'entraînement 130 dans ledit au moins un premier mode de fonctionnement secondaire 160. This mobility of said at least one moon mobile 110 and/or said at least one window 120 can be controlled by at least one control unit allowing the movement of said at least one moon mobile 110 between said at least one first primary position 151 and said at least one second primary position 152 via said at least one drive member 130 in said at least one first primary operating mode 150 and/or said at least one window 120 between said at least one first secondary position 161 and said at least one second secondary position 162 via said at least one drive member 130 in said at least one first secondary operating mode 160.

Ladite au moins une unité de commande est configurée pour recevoir un ensemble de données 170 pouvant comporter au moins une date 171, au moins une heure 172 et/ou au moins une position géographique 173, de préférence indiquée par les trigrammes des aéroports comme certaines montres proposant plusieurs fuseaux horaires, figure 3.Said at least one control unit is configured to receive a set of data 170 which may include at least one date 171, at least one time 172 and/or at least one geographic position 173, preferably indicated by airport trigrams like certain watches offering several time zones, figure 3 .

En effet, selon les modes de réalisation, ladite au moins une première position primaire 151, ladite au moins une deuxième position primaire 152, ladite au moins une première position secondaire 161 et/ou ladite au moins une deuxième position secondaire 162 peut être déterminée ou peuvent être déterminées par l'utilisateur et/ou par ladite au moins une unité de commande via ledit ensemble de données 170 qui peut être reçu par ladite au moins une unité de commande via communication par radio fréquence, via géo-positionnement par satellite, et/ou via communication filaire et/ou lumineuse ou introduit manuellement de sorte que les différentes phases de Lune soient reproduites le plus fidèlement possible et que ce soit à la demande de l'utilisateur et/ou que ce soit de manière automatique par ladite au moins une unité de commande. Par ailleurs, il n'est pas exclu d'introduire la position ou une latitude manuellement, pour une montre mécanique par exemple, à l'aide d'une couronne ou d'une lunette.Indeed, according to the embodiments, said at least one first primary position 151, said at least one second primary position 152, said at least one first secondary position 161 and/or said at least one second secondary position 162 can be determined or can be determined by the user and/or by said at least one control unit. via said data set 170 which can be received by said at least one control unit via radio frequency communication, via satellite geopositioning, and/or via wired and/or light communication or introduced manually so that the different phases of the Moon are reproduced as faithfully as possible and that this is at the request of the user and/or that this is automatically by said at least one control unit. Furthermore, it is not excluded to introduce the position or a latitude manually, for a mechanical watch for example, using a crown or a bezel.

Un des avantages offerts par ledit au moins une unité de commande est de permettre de commander le positionnement dudit au moins un guichet 120 et/ou dudit au moins un mobile de Lune 110 de sorte à reproduire l'image de la Lune dans le ciel ainsi que le mouvement des structures éclairées, c'est-à-dire le phénomène de libration lunaire, dans l'hémisphère Nord et/ou dans l'hémisphère Sud.One of the advantages offered by said at least one control unit is to make it possible to control the positioning of said at least one window 120 and/or said at least one Moon mobile 110 so as to reproduce the image of the Moon in the sky as well as the movement of the illuminated structures, i.e. the phenomenon of lunar libration, in the Northern hemisphere and/or in the Southern hemisphere.

Il est également possible, grâce à ces dispositions, de représenter différentes phases de Lune reproduisant le plus fidèlement possible la position, comme l'élévation de la Lune dans le ciel.It is also possible, thanks to these provisions, to represent different phases of the Moon reproducing as faithfully as possible the position, such as the elevation of the Moon in the sky.

Premier mode de réalisationFirst embodiment

Dans ce premier mode de réalisation représenté sur les figures 4A et 4B, ledit dispositif d'affichage 100 peut fonctionner selon ledit au moins un premier mode de fonctionnement primaire 150 et/ou selon ledit au moins un deuxième mode de fonctionnement secondaire 169. In this first embodiment shown in the Figures 4A and 4B , said display device 100 can operate according to said at least one first primary operating mode 150 and/or according to said at least one second secondary operating mode 169.

En effet, ledit au moins un mobile de Lune 110, visible sur la figure 4A, peut être mobile en rotation selon ledit premier axe 111 entre ladite au moins une première position primaire 151 et ladite au moins une deuxième position primaire 152 dans ledit au moins un premier mode de fonctionnement primaire 150. Ledit au moins un guichet 120, quant à lui, peut être immobile selon ledit au moins un deuxième mode de fonctionnement secondaire 169, figure 4B.Indeed, said at least one Moon mobile 110, visible on the Figure 4A , can be movable in rotation along said first axis 111 between said at least one first primary position 151 and said at least one second primary position 152 in said at least one first primary operating mode 150. Said at least one window 120, for its part, can be stationary according to said at least one second secondary operating mode 169, Figure 4B .

Sans demande de l'utilisateur ou modification dudit ensemble de données 170, comme par exemple une modification de ladite au moins une position géographique 173, ledit au moins un mobile de Lune 110, figure 7, se déplace, au fur et à mesure du temps, selon ledit premier axe 111 entre ladite au moins une première position primaire 151 et ladite au moins une deuxième position primaire 152 dans ledit au moins un premier mode de fonctionnement primaire 150 et ledit au moins un guichet 120 reste immobile selon ledit au moins un deuxième mode de fonctionnement secondaire 169, figure 7.Without user request or modification of said data set 170, such as for example a modification of said at least one geographic position 173, said at least one Moon mobile 110, figure 7 , moves, over time, along said first axis 111 between said at least one first primary position 151 and said at least one second primary position 152 in said at least one first primary operating mode 150 and said at least one window 120 remains stationary according to said at least one second secondary operating mode 169, figure 7 .
