  • said axis of symmetry is arranged parallel to the six o'clock-noon axis of said timepiece.
  • the amplitude of said aperture in a direction perpendicular to said axis of symmetry defines a time range limited to a few hours so as to visualize the time of day, with respect to the noon hour, at approximately more or less two hours around the present moment.
  • the invention also relates to a timepiece comprising a movement arranged to drive a twenty-four hour wheel that includes such a device, characterized in that it comprises a dial or a bearing surface of said window, window of which axis of symmetry is arranged parallel to the axis six o'clock in the afternoon of said timepiece.
  • the AM / PM display is made with a single disc.
  • the user During the daytime range, thanks to a progressive end-of-night indicator near the hub of the disc, and to a progressive night-start indicator on the periphery of the same disc, the user immediately determines the proximity, respectively of the blade and the blade. of twilight. This progressivity is symmetrical.
  • the invention relates to the field of timepieces, and especially those which include a visual display of the hour over twelve hours, and which are the most widespread. It relates more particularly to a display allowing the user to know if the present moment is the morning or the afternoon, and to estimate the difference with respect to the hour of noon.
  • the invention thus relates to an AM / PM 1 display disc for a timepiece, rotating in twenty four hours about an axis of rotation 2, in a direction of rotation A, preferably the direction of the hands of a shows.
  • This disk 1 comprises a graphic display comprising a first surface 3 and a second surface 4 juxtaposed, contiguous, and of similar shape.
  • the disk 1 is designed to be seen partially through a window 20 of a display device 100 arranged to be integrated into a timepiece.
  • the first surface 3 comprises a first decoration corresponding to the day, and the second surface 4 a second decoration corresponding to the night and different from the first decoration.
  • These decorations are very different from each other, for example in flat colors evoking one night like black, and the other day like blue or a light shade.
  • the first surface 3 and the second surface 4 are delimited, between a hub of radius r centered on the axis of rotation 2, and the periphery 6 of radius R of the disk 1, by a first boundary curve 7. which symbolizes the passage from night to day, and a second border curve 8 which symbolizes the passage from day to night.
  • first boundary curve 7 which symbolizes the passage from night to day
  • second border curve 8 which symbolizes the passage from day to night.
  • the first boundary curve 7 and the second boundary curve 8 have their concavities in the same direction relative to the rotation direction A of the disc 1, as visible on the Figures 1 to 5 .
  • any radial coming from the axis of rotation 2 cuts successively, first one of the first two and second 4 surfaces, then the other, and only between the hub 5 and the periphery 6, only one of the curves borders 7 and 8.
  • a radial 9 issuing from the axis 2 first passes through the first surface 3 corresponding to the day, then the second boundary curve 8, then the second surface 4, before reaching the periphery 6.
  • a radial 10 issuing from the axis 2 first passes through the second surface 4 corresponding to the night, then the first boundary curve 7, then the first surface 3, before reaching the periphery 6.
  • a radial from the axis 2 parallel to the six o'clock axis of the timepiece displays the daytime share and the night portion at the moment considered.
  • each of the boundary curves corresponds to a growth of the radius as a function of the angle at the center of the disk, since its contact with the hub 5 to its contact with the periphery 6, without any cusp point.
  • the boundary curves 7 and 8 have a spiral shape, and can respond to different geometric definitions.
  • a simple way of making the drawing, in a particular embodiment as visible in the figures, is to realize them in the form of semicircles, tangent to the periphery 6, and secants or tangents with the hub 5. In the latter case, the point of tangency with the hub 5 is on the side of the latter opposite to that facing its point of peripheral tangency.
  • the radius of these semicircles is between the minimum R / 2 value to avoid any reversal, and the maximum value (R + r) / 2 and which corresponds to a preferred embodiment of a boundary curve tangent to the hub 5 of the opposite side to that of its point of tangency with the periphery 6, this maximum boundary curve also meeting the requirement for a given radial to cut only one boundary curve between the hub and the periphery.
  • R + r the maximum value
  • the first boundary curve 7 and the second boundary curve 8 are identical, and offset from a certain angle to the center ⁇ .
  • this angle ⁇ which illustrates the relative proportion of day and night during a 24-hour day, depends both on the latitude of the place and the time of the year. It is obviously possible to multiply the disks, with for example a different disk per season, and to move a cache including the wicket 20, and having a sequence of 3 months, for each moment to obscure three disks and let appear the fourth these discs can all be driven permanently by the same wheel 24 hours of movement of the timepiece.
  • the available space generally does not allow such a multiplication of the disks, it can be limited to a mean representation, as visible in the figures, wherein the first day surface 3 is greater than the second night surface 4, and where the angle ⁇ is therefore less than 180 °.
  • the AM / PM display proposed by the invention is a deliberate display that allows the user to quickly identify the time of day when he is in a situation where he can lose his usual bearings as the notion of time, for example during a stay of several days in artificial lighting, or during the Arctic night, or travel, or other.
  • the precise display of the time remains done by the display of the timepiece, and what is useful to the user is to know instantly, by a graphic display, if the time is in the morning, or evening or at night.
  • the value of radius r is then zero, and the boundary curves 7 and 8 pass through axis 2.
  • they are half-circles of radius R / 2.
  • the disk can still have, as in the example of the figure 1 , radial graduations 11 defining two by two a time range of defined amplitude, on either side of the representation of the midi of the disc, made in particular by a particular graduation 12, for example a double line as visible on the figure 1 , at least on the whole of the first surface 3.
  • These time ranges can be hourly, or bi-hourly more easily readable on a disc of small diameter. The user can, thus, estimate the time range separating it from the hour of noon.
  • the disc 1 may also include concentric graduations 13 to highlight a better visibility of the day and the night.
  • the disc 1 has a symbol 14 positioned at the noon hour of the disc.
  • the invention also relates to a display device AM / PM 100 for a timepiece, comprising such an AM / PM display disc 1 and a window 20 on a dial 21 arranged to be integrated into a timepiece.
  • the disc 1 is partially visible through this aperture 20.
  • the axis of rotation 2 of the disc 1 is outside or tangential to the aperture 20, and this aperture 20 is of lenticular shape and substantially symmetrical with respect to an axis of symmetry 22, which passes through this axis of rotation 2.
  • This axis of symmetry is preferably arranged parallel to the axis six o'clock in the afternoon of the timepiece in which the device 100 is incorporated.
  • the surface of the aperture 20 farthest from the axis of rotation 2 of the disk 1 is circular and corresponds to the periphery 6 thereof.
  • the hub 5 of the disk 1 is not visible and is hidden by the window.
  • the amplitude of the aperture 20, in a direction perpendicular to this axis of symmetry 22, defines an amplitude of time limited to a few hours, 4 to 5 hours, for example, so as to visualize the time of day, with respect to the time from noon, to about plus or minus two hours around the present moment.
  • the user From the axis 2 towards the periphery 6, the user always sees, during the day, on the right of the window 20, a part of the second surface 4 of night decoration near the axis 2 in the morning; this part of the night scenery disappears around noon, a part of night scenery reappears in the afternoon, but this time on the periphery 6 and no longer near axis 2 (the night "falls") .
  • the invention also relates to a timepiece comprising a movement arranged to drive a twenty-four hour wheel that includes such a device 100.
  • This timepiece comprises a dial 21 or a bearing surface of the window 20, a counter with the axis of symmetry is arranged parallel to the axis six o'clock in the afternoon of this timepiece.
  • the AM / PM display is made with a single disk 1.
  • the display device 100 comprises a device for adjusting the disk in angular position, so as to display the true solar time offset from the legal time.
  • it comprises a device for orienting the disk by a time equation cam.
