    Description: [0001] The present invention relates to the field of watchmaking, more particularly to a timepiece comprising a day and night display mechanism of the planet Earth.
    [0002] Astronomical watches are known from the state of the art, and in particular WO 9 111 756 describes a moon display with a first circular plate held in rotation by a mechanism for driving the watch, with a sphere the moon, movable with this circular support along a window arranged in the dial of the watch. The drive mechanism comprises means for rotating the circular support relative to the window, with a speed corresponding to the speed of the apparent movement of the moon in the sky between its rising and setting. The mechanism rotates a second plate at a speed slightly different from that of the first plate, the second plate drives a pinion that rotates the sphere rotates about an axis parallel to the dial of the watch.
    [0003] The technical article of the Jahrbuch der deutschen Gesellschaft für Chronometrie, in the name of GLASER "Astronomische Indikationen bei Uhren", published on 01.01.1989, vol. 40, pages 139-161, describes a representation of the moon phases by means of a rotating sphere or rotating disks. A differential drive drives at suitable speeds, on the one hand the sphere rotating on its axis, and on the other hand this axis in rotation relative to the dial.
    The invention proposes to incorporate into a wristwatch a visual indication very simple and visible day and night on Earth.
    According to the invention, a timepiece comprises a timepiece comprising a viewing mechanism of day and night. The viewing mechanism includes a globe representing the earth, a half-sphere element that partially encloses the globe and is rotated around the globe. The visualization mechanism further comprises a device for driving the half-sphere element around the globe by one turn per day, the half-sphere element hiding or obscuring the part of the globe where it covers it to represent at night, the element in half-sphere leaving visible the part of the globe that it does not cover to visualize the day.
    In one embodiment, the globe of the viewing mechanism is disposed in the center of a dial space extending to the periphery of an opening in a housing of the timepiece.
    In another embodiment, a gear train of a watch movement is arranged to rotate the globe about its axis in a clockwise direction.
    According to this same alternative embodiment, the half-sphere element is integral with a ratchet movable driven by a gear train so that when a time setting function. movement is engaged, a rotation of the indicator members in a clockwise direction, rotates the half-sphere element in a clockwise direction by the ratchet which remains indexed to the time function. On the contrary, always when a motion time-setting function is engaged, a rotation of the indicator members in a counter-clockwise direction deindexes the half-sphere element of the time function to allow adjustment of the day and time display. night by a rotation of the half-sphere element in a counterclockwise direction.
    In one embodiment, the half-sphere element is bordered by a hoop.
    In a preferred embodiment, the half-sphere element comprises a smoked or translucent glass so that the entire globe is visible, including a partially obscured part.
    In a variant, the half-sphere element is opaque to cover the entire part of the globe where it is dark and leaving visible only the part of the globe where it is day.
    The characteristics of the invention will appear more clearly on reading the description of several embodiments given solely by way of example, in no way limiting with reference to the schematic figures, in which:
    Fig. 1 is a perspective view of a wristwatch box comprising a watch movement and a display mechanism of the day of the night of the planet Earth;
    Fig. 2 is a partial exploded view of the night-time display mechanism of the planet earth of FIG. 1;
    Fig. 3 is a perspective view of FIG. 2 assembly;
    Fig. 4 is a perspective view of the watch movement carrying the day night display mechanism of the Earth; and
    Fig. 5 is a side view of FIG. 4.
    As illustrated in FIG. 1, a wristwatch comprises, inside the watch case 1, four modules 2, 3, 4, 5 carried by a frame 6 with four arms which each drive modules 2, 3, 4, 5 in a movement circular circular permanent periphery of the watch case 1. In this example, a complete rotation of the frame 6 takes place in twenty minutes. The modules 2, 3, 4, 5 are a movable dial 5, a vortex 2, a minute indicator member 4 and another decorative element 3 namely a gemstone.
    According to this embodiment, the globe 51 of the day night display mechanism is arranged in the center of a movement and rotates with the frame 6.
    On the top of the watch, a sapphire crystal 7 provides a top view of the four modules 2, 3, 4, 5 and the central display mechanism day and night. The watch case 1 further comprises on its middle band 13, a transparent cylinder 14 arranged between four horns 15, the transparent cylinder 14 revealing the modules 2, 3, 4, 5 internal to the watch case and the mechanism central display day and night.
    In contrast to the whirlpool module 2, the perforated dial 10 hours and minutes has a perfect readability. Moreover, while it is rotated by a central frame 6, the dial 10 keeps the same orientation, the index 16 disposed at the top of the dial 10 remains at the top of the dial 10.
    On one of the arms, a first cage of the vortex containing an escapement / sprung-balance, is rotatably mounted about a first axis normal to a plane defined by the sprung balance. A second vortex cage supports the first cage and is rotatably mounted about a second axis normal to said first axis.
    The second axis extends radially from a central portion of a dial space of the timepiece, the dial space extending to the periphery of an opening in a housing 1 of the timepiece.
    The second axis is rotatably mounted about the third axis normal to the plane of the dial space and disposed in its central portion so that during a rotation about the third axis, the assembly formed by the first cage and the second cage rotates around the third axis and around the dial space.
    The third arm carries the module 4 indicating the seconds. The module makes one revolution per minute around a radial axis.
    The other decorative element 3 is carried by an additional radial arm extending from the third axis, forming a cross with said radial arm and the second axis, the additional arm carrying a gemstone.
    In this example, each arm carried by the central axis rotates clockwise around the central axis 9.
    As illustrated in FIGS. 1 to 5, the timepiece comprises a viewing mechanism of day and night. The display mechanism includes, in the center, a globe 51 representing the earth, a half-sphere element 53 which partially encloses the globe 51 and is rotatably mounted around the globe 51. The viewing mechanism also comprises a driving device of the half-sphere element 53 around the globe 51 by one turn per day. The half-sphere element 53 hides the part of the globe 51 where it covers it to represent the night, the half-sphere element 53 leaving visible the part of the globe 53 that it does not cover to visualize the day.
    In this example, the frame 6 rotates, clockwise, around the central axis 9 in 20 minutes. A transmission begins on the mobile 32, in particular used for setting time, but it is also rotated during normal operation. A pinion 60 is driven on this mobile 32. From this pinion 60, a gear train 61,62, 63 drives a ratchet wheel 64. A bow 52 with a half-sphere 53 is integral with the ratchet wheel 64. The earth 51 is fixed to the frame 6, it does not rotate relative to the chassis but makes a turn in 20 minutes as the frame 6.
    The hoop 52 is one turn per day with respect to the frame 6 and therefore with respect to the earth 51. A half-sphere smoke 53 integral with the hoop 52 can indicate the day and night on the Earth.
    For correction, the ratchet wheel 64 allows, when setting the time clockwise to rotate the hoop 52 while remaining indexed hours. When the time setting is in the counterclockwise direction, the hoop 52 remains in place and thus deindexes the hour-minute display. This configuration allows you to set the day-night display with the display of hours and minutes.
    The timepiece according to the present invention may comprise a tri-axial vortex comprising a first vortex cage containing an escapement / sprung balance-spring, the first cage being rotated about a first normal axis relative to a plane defined by the spiral balance. The tri-axial tourbillon timepiece comprises a second vortex cage which supports the first cage and is rotatably mounted about a second axis normal to said first axis, the second axis extending radially from a central part of a dial space of the timepiece. The dial space extends to the periphery of an opening in a case of the timepiece. The second axis is rotatably mounted about a third axis normal to the plane of the dial space and disposed in its central part so that during a rotation about the third axis, the assembly formed by the first cage and the second cage rotates around the third axis and around the dial space.
    The timepiece according to the present invention may also comprise a first central axis arranged in the center of a dial space extending to the periphery of an opening in a case of the timepiece, around which first axis is arranged an indexing wheel. The timepiece further comprises at least one arm rotated about the first central axis, a free end of said arm carrying a dial. The dial carries an indicator organ
