Description

BRIEF DESCRIPTION OF THE DRAWING

[0022] The invention will be described below in a more detailed manner using the appended drawing, given as an example that is in no way limiting, in which the only drawing shows a watch comprising a dial and a watch glass according to one embodiment.

DETAILED DESCRIPTION OF THE INVENTION

[0023] The only drawing shows an embodiment of the present invention in the form of a watch glass 100 disposed on a watch 300 and more particularly on a watch dial 200 comprising at least one indication 201 for example such as the hour or the minute.

[0024] Said watch glass 100 of the present invention comprises at least one first chamber 110 in which at least one first mobile element 210, typically a ball and preferably made of ferromagnetic material, can move freely.

[0025] “Move freely” should be understood as there not existing any obstacle to the movement of said at least one first mobile element 210. Indeed, said at least one first chamber 110 is comprised between said watch dial 200 with at least one indication 201 and at least one upper wall 101 distant from said watch dial 200, that is to say that they are separated by a space, and at least one lateral wall.

[0026] Said at least one lateral wall 102 is comprised between said at least one upper wall 101 and said watch dial 200 on the one hand, and on the other hand said at least one lateral wall 102 surrounds said at least one first chamber 110, as shown in the only drawing, so that said at least one upper wall 101 and said at least one lateral wall 102 form said at least one first chamber 110.

[0027] As visible in the only drawing, said at least one lateral wall 102 is thicker than said at least one upper wall 101. Indeed, the thickness of said at least one upper wall 106 is smaller than the thickness of said at least one lateral wall 107.

[0028] Thus, the ball 201 or the balls 201 are confined, in other words said at least one first mobile element 210 is confined in a limited space, that is to say that of said at least one first chamber 110, which limits its movement and avoids said at least one first mobile element 210 hitting a location of the watch glass 100 on the one hand and on the other hand, and the shock of said at least one first mobile element 210 on the watch glass 100 being too great.

[0029] Thus, these balls can hit the watch glass 100 without damaging the glass, since the thickness of said at least one lateral wall 107 is large enough to dissipate the energy of the shock of said at least one first mobile element 210, and this does not negatively affect the appearance of the watch and thus cannot degrade the readability of the indications 201 of the dial.

[0030] It is also possible to provide another indication on said watch dial and to do this said watch glass 100 can comprise at least one second chamber 120 configured to comprise at least one second mobile element 220, typically a ball and preferably made of ferromagnetic material, and at least one peripheral wall 103 configured to form said at least one second chamber 120.

[0031] Said at least one peripheral wall 103 also comprises a thickness, but since said at least one peripheral wall 103 forms said at least one second chamber 120 and the latter, that is to say said at least one second chamber 120, surrounds said at least one lateral wall 102 and/or said at least one first chamber 110 and consequently said at least one peripheral wall 103 surrounds said at least one lateral wall 102 and/or said at least one second chamber 120, so that said at least one second mobile element 220 is relatively limited in its movements in comparison to said at least one first mobile element 210, since said at least one second mobile element 220 is confined in a space comprised between said at least one lateral wall 102 and said at least one peripheral wall 103.

[0032] Of course, according to the geometry that said watch dial 200 can have, the most obvious shape for said at least one peripheral wall 103 is the circular shape since it allows to easily deviate the trajectory of said at least one second mobile element 220, but when said watch dial 200 comprises straight lines, it is natural to dispose said at least one lateral wall 102 outside of said watch 300 in order to avoid said at least one first mobile element 210 from inflicting too an impact on the watch glass 200 due to the length of its trajectory.

[0033] Another advantage that can be drawn from the thickness of said at least one lateral wall 107 is the eyeglass effect since being thicker than said at least one upper wall 101, the thickness of said at least one lateral wall 107 allows to obtain from said at least one indication 201 an enlarged image. In other words, said at least one separation wall 102 has an eyeglass effect.

[0034] These various embodiments can be implemented in a watch 300 comprising a watch dial 200, as described above.

[0035] Said watch 300 comprises at least one first magnetised hand 310 located under the watch dial 200 so as to move said at least one first mobile element 210 made of ferromagnetic material through said watch dial 200 and at least one second magnetised hand 320 also located under the watch dial 200 and also being able to move said at least one second mobile element 220 made of ferromagnetic material through said watch dial 200. Thus, the balls are moved in a limited space thanks to the magnetised hands so as to indicate a piece of information, for example such as the hour or the minutes, which limits their movements and avoids the balls simultaneously hitting a location of the watch glass 100 on the one hand and on the other hand, and the shock of one of the balls on the watch glass 100 being too great. Thus, these balls can hit the watch glass 100 without damaging the glass and without negatively affecting the appearance of the watch and thus degrading the readability of the indications 201 of the dial.
