    Description: [0001] The present invention relates to a watch movement intended to display information relating to the Moon.
    It is known to display the phases of the Moon, information that corresponds to the lunar or synodic lunar month, that is to say, the interval between two new consecutive moons. The synodic month is about 29.53 days (more precisely 29,530,58885 days).
    Two other types of period of revolution are also interesting to characterize the moon. It is first the draconian lunar month, that is to say the interval between two passages of the Moon at the same node of its orbit. Nodes are the points where the lunar orbit cuts the ecliptic. The point where it crosses the ecliptic from the southern hemisphere to the northern hemisphere is called ascending knot or north knot (symbol Ω); the one where it crosses it from the northern hemisphere to the southern hemisphere is called descending node or south node (symbol O). The draconian month is about 27.21 days (more precisely 27,212,221 days). The date of the lunar draconitic month makes it possible to characterize the height of the Moon (that is to say its inclination relative to the ecliptic) for an observer on Earth.
    As for the anomalous lunar month, it is the interval between two perigee of the Moon, that is to say the point of its orbit closest to the Earth. The anomalous month is approximately 27.55 days (more precisely 27.55455 days). The date of the anomalous lunar month makes it possible to characterize the size of the Moon (its distance from the Earth) for an observer on Earth.
    The combination of information on the moon phase and the draconian month can predict an "eclipse season". Indeed, a solar eclipse occurs when the Moon, in its new phase, moves to the ascending or descending node, while a lunar eclipse occurs when the Moon, in its full phase, passes to the ascending or descending node.
    The object of the present invention is to provide a watch movement for a timepiece for displaying information relating to the moon.
    The present invention relates to a watch movement according to claim 1 and a timepiece according to claim 8.
    The accompanying figures illustrate schematically and by way of example an embodiment of the watch movement according to the invention.
    Fig. 1 illustrates the various displays of the movement according to the invention.
    Figs. 2 and 3 illustrate the work train of the invention.
    Fig. 4 illustrates the position of the Moon in a spherical landmark centered on the Earth and one of whose axes (abs cisse or ordinate) points towards the Sun.
    The movement according to the invention is intended to equip a timepiece and can display information relating to the moon and in particular to the lunar months. In addition to the traditional "moon phase" information, the movement displays "Moon size" information and, preferably, "Moon height" information. Preferably, the movement is also arranged to display the current year.
    The size of the Moon corresponds to its distance from the Earth. The Moon reaches its perigee when it reaches the point of its orbit closest to the Earth. Conversely, it is at its peak when it reaches the point of its orbit farthest from the Earth. The anomalistic month refers to the time interval between two perigee.
    The height of the Moon corresponds to the position of the Moon relative to the ecliptic. The inclination of the plane of the lunar orbit relative to the plane of the ecliptic varies from + 5 ° to -5 °. The draconitic month refers to the time interval between two passages at the same node (Ω or O, lunar orbit and ecliptic intersection).
    Thus, as illustrated in FIG. 4, the three-dimensional spatial position of the Moon with respect to the Earth and the Sun is decomposed into three parameters determined in a spherical coordinate system centered on the Earth and one of whose axes (abscissa or ordinate) points towards the Sun. The phase of the Moon is characterized by the value of the angle θ, the size of the Moon is characterized by the radius r while the height of the Moon is characterized by the angle φ.
    In a traditional manner, the movement according to the invention comprises a driving member, a regulating member and a finishing train (not shown) connecting the drive member to the regulating member for transmitting the energy of the first to second. These elements are well known and will not be described in more detail.
    The movement according to the invention further comprises a lunar wheel illustrated in FIGS. 2 and 3. The moon gear comprises a drive wheel 1 consisting of a drive gear 11 and a correction star 12. The drive pinion 11 is engaged with a moving wheel of the movement finishing and constitutes the power take-off of said lunar wheel. The correction star 12 may be engaged with a correction mechanism 13 operable for example by means of a pusher to advance or retreat the mechanism of a day (solar).
    The drive pinion 11 is engaged with the wheel 21 of a first synodic intermediate mobile 2. Said first synodic intermediate mobile 2 further comprises a pinion 22 integral with the wheel 21 and meshing with a wheel 31 of a second synodic intermediate wheel 3. A pinion 32 is secured to the wheel 31 of the second synodic intermediate wheel 3 and is engaged with the wheel 41 of a mobile of synodic month 4. This synodic month mobile 4 further comprises a pinion 42 in the illustrated embodiment, this moon phase indicator 43 is in the form of a disk on which are drawn two representations of the full Moon. preferably light in color on a dark background. Said moon phase indicator 43 cooperates with a circular window 44 to display the phase of the Moon (new, first crescent, first quarter, full, gibbous, last crescent, last quarter). Any other appropriate indicator may be used. The gear of the display mechanism according to the invention is arranged so that the mobile of synodic month 4 performs a turn in 29,530,58885 days (duration of a synodic lunar month).
    The pinion 42 of the synodic month mobile 4 is engaged with the wheel 51 of an anomalous intermediate mobile 5. The anomalous intermediate mobile 5 further comprises a pinion 52 integral with the wheel 51 and which meshes with an anomalous mobile 6. The anomalous mobile 6 carries an anomalistic month indicator 61. In the illustrated embodiment, this anomalous month indicator 61 has the form of a disc bearing a representation of the Moon and intended to cooperate with an ice 62 on which is represented lunar orbit 63 and Earth 64, the ice 62 and the indicator 61 being visible through a window 65. The anomalistic month indicator 61 and the ice 62 together form a display of the anomalous month giving information on the size of the Moon. Any other appropriate indicator to display information related to the anomalous month can be used (indication of the apogee or perigee of the Moon, number of days remaining before the next perigee ...). The gear train and the anomalous mobile 6 are arranged so that the latter performs a lap in 27.55455 days (duration of the anomalous lunar month).
    The second synodic intermediate mobile 3 also causes a second kinematic chain for displaying the height of the Moon (draconian month) and the year. The wheel 31 of the second synodic intermediate wheel 3 meshes with the wheel 71 of a first draconitic intermediate wheel 7 whose pinion 72 is in engagement with the wheel 81 of a second draconitic intermediate wheel 8. Said second draconitic intermediate wheel 8 comprises in addition to a pinion 82 integral with the wheel 81 and which drives the wheel 91 of a mobile of the draconitic month 9.
    The mobile of the draconitic month 9 carries a draconitic month indicator 92. In the illustrated embodiment, this draconitic month indicator 92 is in the form of a disc bearing a representation of the Moon and rotating under a mirror 93 on which are represented the ascending nodes Q and descending U, the Sun and a graduation 95. The ice 93 and the draconian month indicator 92 are visible through a window 94. The representation of the Sun could also be carried by the Draconitic month indicator disc 92. The gear wheel and the draconitic month wheel 9 are arranged for the latter to perform a turn in 27.212221 days (duration of a draconian lunar month). Any other appropriate draconitic month indicator may be used.
    The mobile of the draconitic month 9 further comprises a pinion 96 which drives a wheel 101 of a first intermediate mobile years 10 whose pinion 102 drives a wheel 201 of a second mobile intermediate 20 years. This second mobile In the 1920s, the middle finger also includes a pinion 202 engaged with a 30's wheel bearing a finger from the 30's. The finger of the 301's is arranged to rotate once a year a coach of the 1940's who is in turn taken with an indicator of the 50s and an indicator of the decades 60. The indicator of the 50s carries a record of the units 501 while the indicator of the decades 60 carries a record of tens 502. The gear is arranged so that the indicator 50's takes one step per year and one turn in 10 years while the 60's indicator takes a step every 10 years and a turn in 100 years.
    In the illustrated embodiment, the display of the 50s, 60s, 501, 502 allows to adjust the mechanism using the periodicity of the relative positions of the Earth, the Moon and the Sun (saros, about 18 years: saros is, in astronomy, a period of 223 synodic months A saros after an eclipse, the Sun, the Earth and the Moon find approximately the same relative geometry).
    Thus a watch movement is made to display several information relating to the Moon: phase, height and size of the Moon. Thanks to all this information, it is possible to know if one is in a "solar or lunar eclipse season". Indeed, a solar eclipse occurs when the Moon in its new phase passes to the ascending or descending node, while a lunar eclipse occurs when the Moon in its full phase passes to the ascending or descending node. These configurations happen about twice a year. It is possible to indicate their occurrence, for example by means of an eclipse indicator visible in a window.
    In a preferred manner and as illustrated in the figures, the lunar gear of the movement according to the invention is in the form of an independent gear train of the finishing train or an additional module easily integrable with a conventional clockwork movement. .
