    Field of the invention
    The invention relates to a double-sided display timepiece, comprising a supporting structure of at least one movement, and comprising on a first side of said structure first display means, and on a second side of said structure opposite said first side of the second display means, and comprising at least a first integral pair of displays comprising, coaxial along a first common axis and integral with a first common shaft, on said first side a first display which comprises said first display means, and on said second side a second display which said second display means comprise.
    The invention relates to the field of clockwork display mechanisms.
    Background of the invention
    [0003] The market for timepieces, and in particular watches, is in need of event models, or exclusive, or in limited series, as well as complications at an affordable price. Visual animations are part of the answers that manufacturers can provide, and they often contribute to the notoriety of a watch. While certain horological functions are conventionally displayed on a first face of the timepiece, such as the top of the watch, it is often possible to implant complications, or other functions, on the opposite face, in particular when the watch has or does not have an oscillating weight of small diameter; it is also known that the oscillating weight can also constitute an information medium, while generally requiring a differential device, which increases the thickness and the cost price of the watch.
    The installation of any mobile requires guides, synonyms of thickness, and the addition of additional displays often comes up against this constraint of size. Again, it is a matter of not disturbing the chronometric performance of a timepiece when driving trains of moving bodies, the balancing of which may not be optimal, especially in the case of displays.
    Summary of the invention
    The invention proposes to install an additional display, on the side opposite to a conventional main display often desired by the user. More particularly, the invention is designed to produce such an additional display in the form of a visual animation.
    [0006] To this end, the invention relates to a timepiece with a double-sided display, according to claim 1.
    The figures whose description follows are an example of an event-driven timepiece, in this case a watch dedicated to the anniversary of a space mission during which the astronauts wore a watch from the same family.

    Detailed description of the preferred embodiments
    The invention relates to a timepiece 1000, in particular a watch, with a double-sided display.
    This timepiece 1000 comprises a structure 2000 carrying at least one movement 3000, and it comprises on a first side of the structure 2000 first display means 100, and on a second side of the structure 2000 opposite to the first side of the second display means 200.
    The timepiece 1000 comprises at least a first couple of integral displays, which comprises, coaxial along a first common axis D1 and integral with a first common shaft 10, on the first side a first display 1 that comprise the first display means 100, and on the second side a second display 2 which the second display means 200 comprise.
    According to the invention, the center of mass of the first display 1 and the center of mass of the second display 2 are, in projection on a plane perpendicular to the first common axis D1, aligned with the first common axis D1 or coincident with it .
    More particularly, the center of mass of the first display 1 and the center of mass of the second display 2 are, in projection on a plane perpendicular to the first common axis D1, on either side of the common axis D. This 180 ° configuration is advantageous because it drastically reduces the resulting unbalance.
    In another configuration, the center of mass of the first display 1 and the center of mass of the second display 2 are, in projection on a plane perpendicular to the first common axis D1, on the same side of the first common axis D1. Preferably, this configuration is reserved for the use of low unbalance displays.
    More particularly, the first display 1 and the second display 2 have, relative to the first common axis D1, respectively a first moment of inertia relative to the axis and a second moment of inertia. Their respective inertias are less than or equal to 0.388 g.mm <2>. More particularly, their respective inertias are less than or equal to 0.248 g.mm <2>.
    More particularly the first inertia is less than or equal to 0.14 g.mm <2>.
    More particularly, the second inertia is less than or equal to 0.14 g.mm <2>.
    More particularly, the first display 1 or / and the second display 2 is a needle comprising a needle body, extending radially with respect to the first common axis D1, which is made of light alloy, in particular of alloy of aluminum and / or titanium, or silica glass, or at least partially amorphous material, or Plexiglas, or injected resin, or the like.
    Preferably, the resulting overall inertia of the first display 1 and of the second display 2 is less than or equal to 0.55 g.mm <2>.
    It is advantageous to minimize the value of inertia; it can also be canceled by playing on the geometry and / or the materials on either side of the axis.
    [0021] In particular, the timepiece 1000 is a watch, which comprises on the first side at least the display of at least one horological function, such as the display of the time, or of the calendar, or a chronograph function, and on the second side a visual animation which is arranged to operate, either continuously under the drive of the movement 3000, or discontinuously at the request of the user by an action to control a function horological, such as the chronograph function, or by an action on control means 4000 of the animation or of a minute repeater or of another function included in the timepiece 1000.
    More particularly, the timepiece 1000 thus comprises control means 4000, which are arranged to trigger at the request of the user of the timepiece 1000 a function making simultaneously the first display 1 and the second display 2.
    More particularly, the first display 1 and the second display 2 which are arranged for the display of different functions.
    More particularly, the first display 1 or the second display 2 is a chronograph display.
    More particularly, the first display 1 and / or the second display 2 is arranged for the display of a visual animation.
    The invention is illustrated, in a particular and non-limiting manner, by the figures which represent a chronograph display as the first display 100, and a visual animation display as the second display.
    More particularly, at least the first display 1 or the second display 2 (as in the case of the figures), which is arranged for the display of a visual animation, is movable above a background 5. This display dedicated to visual animation is still mobile, or else above a mask 6 partially and not completely covering the background 5 by releasing a visible area 7 contiguous to a hidden area 8 in which the background 5 is not not visible by the user of the timepiece 1000, or else between the back 5 and the mask 6 while moving above the visible zone 7 or the hidden zone 8 according to its angular position with respect to the axis common D.
    More particularly, the mask 6 is provided at the level of a glass 60 closing the timepiece on the second side, the bottom 5 comprises at least one window 9 through which is visible at least a third display 3, and the second display 2 is movable between the bottom 5 and the glass 60. This mask 6 can be produced by screen printing, decal, surface treatment of the glass 60, painting, enamelling, or the like. It can also consist of a disk plated directly under the mirror 60, which comprises an opaque or substantially opaque part above the hidden zone 8, and a transparent or substantially transparent part defining the visible zone 7.
    More particularly, at least the bottom 5 or the mask 6 comprises at least one window 9, through which is visible at least a third display 3. In the variant illustrated by the figures, it is the bottom 5 which comprises this window 9.
    Like the second display 2, this at least a third display 3 can, depending on the construction produced, either be permanently driven by the movement 3000, or else only at the request of the user of the timepiece 1000, by action on control means 4000.
    More particularly, and as illustrated by the figures, the timepiece 1000 comprises at least a second integral pair of displays comprising, coaxial along a second common axis D2 and integral with a second common shaft 20, on the third side the third display 3 which comprises the second display means 200, and on the first side a fourth display 4 which comprises the first display means 100.
    More particularly, the center of mass of the third display 3 and the center of mass of the fourth display 4 are, in projection on a plane perpendicular to the second common axis D2, aligned with the second common axis D2 or coincident with it.
    More particularly, the fourth display 4 is a chronograph display.
    The admissible values of inertia and moment of inertia for the third display 3 and the fourth display 4 are similar to those listed above for the first display 1 and the second display 2.
    Preferably, the resulting overall inertia of the first display 1, of the second display 2, of the third display 3, and of the fourth display 4 is less than or equal to 0.55 g.mm <2>.
    More particularly, the background 5 is a representation of an interstellar space, the mask 6 is a representation of a first celestial body, for example the lunar surface, the third display 3 is a representation of a second celestial body , for example the Earth, and the second display 2 is a representation of an astronaut and / or of a spaceship, such as visible in the figures which schematize an astronaut in a spaceship.
    More particularly, the bottom 5 covers the movement 300, and includes a window 50 which is arranged to allow the frontal insertion, in the direction of the first common axis D1, of the bottom 5 on the movement 3000 equipped with the second display 2 on the first common shaft 10, protruding from the movement 3000 at the level of the second side. This window 50 is preferably in the hidden zone 8, and is thus not visible to the user. This arrangement facilitates the assembly of the watch. In a variant not shown, the second display 2 can be a transparent disc carrying a pattern, instead of a needle, its assembly is then less simple.
    More particularly, the first display 1 is a large chronograph second hand, the second display is a representation of an astronaut and / or of a spaceship, as visible in the figures which schematize an astronaut (triangle ) aboard a spaceship (pentagon).
    More particularly, the fourth display 4 is a movable hand above a dial placed at nine o'clock; in a variant, this fourth display 4 can also be a disc carrying an index, or a disc carrying an index, or the like.
    More particularly, for each integral pair of displays that includes the timepiece 1000, the centers of mass of the two displays which make up this integral couple are, in projection on a plane perpendicular to their common axis, aligned with the common axis or confused with it.
    More particularly, the timepiece 1000 is a watch, which comprises on the first side at least the display of a chronograph function, and on the second side a visual animation running, or even continuously under the drive movement 3000, or else discontinuously at the request of the user by a control action of the chronograph function or by an action on control means 4000 of this animation, or of a minute repeater, or of a another function included in the timepiece 1000.
    The invention can be implemented equally well for mechanical timepieces as for quartz, or electric, or electromechanical timepieces, the display of which comprises moving parts, in particular in rotation.
    The invention allows the adaptation of existing movements for the creation of visual animations, at a reasonable cost. The thickness consumption is moderate, insofar as it is not necessary to install additional shaft guides, the additional thickness is limited to the thickness of the mobiles participating in the animation, and to the set of security between them.
    Any timepiece is thus transformable, and also easily customizable, which represents an undeniable commercial advantage.
