    TECHNICAL AREA
    The present invention relates to a watch case and a fastening device of this watch case to a bracelet. PRIOR ART
    The fixing device of a bracelet to a watch case generally comprises, on either side of the watch case, two projecting horns, and a transverse bar whose ends are fixed to each of these horns. The transverse bar is intended to cross a transverse hole arranged inside a bracelet strand.
    Such a fixing device is effective, but relatively complicated because it comprises several different parts that must be assembled. In addition, the change of the watch strap is also complicated, and it often requires adapted tools.
    Other devices for attaching a bracelet to a watch case have been proposed to overcome these drawbacks. Thus, JP H 08 248 149 discloses a watch case having a ring projecting from its side wall. The watch band is inserted into this ring. Such a fixing device is simple, but the watch case is not well attached to the bracelet: indeed, it can slide or rotate relative to the watch strap. The watch can fall.

    Advantageously, the ring is disposed on a transverse wall of the watch case. In the prior art, the crown was disposed on a side wall.
    In this document, is called "transverse wall", a wall of the middle part at the top or bottom of the middle when the watch case is positioned by the user in the direction allowing him to read the time.
    According to one embodiment, the watch case comprises two fixing devices on either side of the middle part, which allows a better maintenance of the watch on the wrist of the user.
    According to one embodiment, the watch case comprises two bodies arranged on either side of the fixing device, which can for example allow to simultaneously display the time in two different time zones.
    A second aspect of the invention relates to a watch comprising a watch case according to the first aspect of the invention and a watch strap inserted into the two through openings of the fastening device.
    The middle part is not aligned with the bracelet.
    The bracelet is offset from the middle part.
    The bracelet extends in a reference plane offset from the middle part.
    [0027] Advantageously, the bracelet comprises a single strand.
    BRIEF DESCRIPTION OF THE FIGURES
    Other features and advantages of the present invention will appear more clearly in the following detailed description of the preferred embodiments, given by way of nonlimiting example with reference to the appended figures, among which: FIG. 1 schematically shows a watch according to one embodiment of the invention; figs. 2 to 5 schematically show a watch according to a second embodiment of the invention; fig. 6 schematically shows a watch according to a third embodiment of the invention.
    DETAILED DESCRIPTION
    Fig. 1 shows a watch according to a first embodiment of the invention. This watch 1 comprises a watch case 2 and a bracelet 3. The watch case has a caseband 4, a bezel 5 and a bottom (not shown in the figure). The bezel 5 protects a display device 10 of the time. The middle part 4 has a parallelepipedal shape. The middle part 4 has two side walls 6 and 7 and two transverse walls 8 and 9. The two side walls 6, 7 are parallel.
    In this document, is called "sidewall", a wall of the middle part at 3 o'clock or 9 o'clock, when the display device is analog, or left or right of the display screen when the display device is digital. The term "transverse wall" refers to a wall of the middle part at 12:00 to 6:00 when the display device is analog, or at the top or bottom of the display screen when the display device is digital. The terms "left", "right", "up" and "down" refer to the direction in which the watch is placed when a user reads the time.
    The watch case 2 comprises a fastening device 11 of the bracelet. This fixing device 11 is located on a side wall 6 or 7 of the middle part 4. The fixing device 11 is therefore located on one side of the middle part. The fixing device 11 comprises two spaced through openings 12 through which the bracelet 3 can be inserted. As shown in the figures, the bracelet thus has two ends located under the fixing device and an intermediate portion located on the fixing device.
    When the bracelet 3 is inserted into the fixing device 11, it is offset with respect to the caseband 4. On the contrary, in the prior art, the bracelet 3 was aligned with the caseband 4.
    The through openings 12 are spaced a distance at least equal to the length of the side walls of the middle part.
    The fastening device 11 preferably comprises a frame 13. This frame 13 comprises two branches 17 extending in two parallel planes to the side walls 6, 7 of the middle part 4. The two branches 17 are connected by two rounded ends 18. The armature 13 has a convex curvature so as to match the shape of the wrist of a user. The armature 13 is secured to the middle part 4. The armature 13 preferably forms a piece integral with the caseband 4. In this embodiment, the armature 13 is metallic.
    The fixing device 11 also comprises two transverse rods 14 arranged so as to form inside the middle 4 two through openings 12 separated by a cavity 15. Each transverse rod 14 preferably extends perpendicular to the reference axis.
    The watch case also comprises at least one ring 16. The ring 16 is disposed on a transverse wall 8 or 9 of the caseband. On the contrary, in the watches of the prior art, the crown was arranged on a side wall of the middle part.
    Figs. 2 to 5 show another embodiment in which the watch case 1 comprises two fixing devices 11 on either side of the caseband 4. Thus, the watch case 1 comprises a fastening device 11 along
