BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The invention will now be described in more detail, by way of non-limiting examples, using the accompanying drawings, in which:

[0051] - Figure 1A shows a sealing device 100 for a watch 200 in at least one first position 101; and

[0052] - Figure 1B The sealing device 100 for a watch 200 is shown in at least one second position 102 . DETAILED DESCRIPTION

[0053] Current crowns provide a certain tightness. However, when high pressures, for example above 300 bar, are reached, it would be disadvantageous to operate a crown that cannot be easily operated in order to ensure this tightness.

[0054] This is not the case with the watch 200 according to the invention, which is sealed at these high pressures thanks to the sealing device 100. In fact, said sealing device 100 for watch 200 (preferably of watch 200) is configured to be inserted into a main space 201 included in a middle part 210 of said watch 200 and comprises at least one insertion mechanism 110, at least one first sealing element group 120, at least one second sealing element group 140 and at least one drive mechanism 130.

[0055] The latter, that is, the at least one driving mechanism 130 can be Figure 1A At least one first position 101 visible in the image is maintained and can be Figure 1B The at least one second position 102 visible in FIG. 1 is driven. The at least one driving mechanism 130 may be Figure 1A The at least one first position 101 and Figure 1B The at least one second position 102 visible in the image is shifted or displaced.

[0056] The retention in the at least one first position 101 can be enabled via at least one retention mechanism 150. The at least one retention mechanism 150 comprises at least one retention element 151 arranged on the at least one insertion mechanism 110, the at least one retention element 151 being configured to detachably cooperate with at least one retention portion 153 arranged on the at least one drive mechanism 130. The at least one insertion mechanism 110 is configured to displace the at least one drive mechanism 130 when the at least one retention element 151 cooperates with the at least one retention portion 153.

[0057] More specifically, the at least one retaining element 151 is an internal thread or an external thread arranged on the inner periphery of the at least one insertion mechanism 110, and opposite to the at least one retaining portion 153, the at least one retaining portion 153 can be in the form of an external thread or an internal thread arranged on the outer periphery of the at least one driving mechanism 130.

[0058] In fact, the at least one insertion mechanism 110 has a hollow cylindrical shape, preferably a tube, and the at least one driving mechanism 130 includes at least one sliding member 139, which is preferably entirely or partially located within the secondary space 131 included in the at least one driving mechanism 130, and the at least one sliding member 139 is configured to slide in the hollow cylindrical shape (preferably the tube).

[0059] As can be seen in the figure, the at least one retaining element 151 is opposite to the at least one retaining portion 153. Preferably, the at least one retaining element 151 is arranged on the inner circumference of the hollow cylindrical part (preferably the tube), and the at least one retaining portion 153 is arranged on the outer circumference of the at least one sliding member 139, so that the at least one driving mechanism 130 can be maintained in the at least one first position 101 and shifted or displaced between the at least one first position 101 and the at least one second position 102.

[0060] As described above, the middle part 210 of the watch 200 includes the main space 201, and the at least one insertion mechanism 110 is inserted into the main space 201. The abutment mechanism 114 included in the at least one insertion mechanism 110 allows the abutment mechanism 114 to abut against the middle part 210 when the at least one insertion mechanism 110 is inserted, and / or abut against the at least one drive mechanism 130 when the at least one drive mechanism 130 is in the first position 101, thereby limiting the insertion of the at least one insertion mechanism 110 into the main space and / or the displacement of the at least one drive mechanism 130. In addition, when the at least one drive mechanism 130 is in the first position 101, contact is generated between the at least one drive mechanism 130 and the abutment mechanism 114, thereby improving the sealing between the secondary space 131 and the at least one drive mechanism 130.

[0061] The at least one driving mechanism 130 further comprises a secondary space 131, which is configured to receive the at least one insertion mechanism 110. A cavity 134 (preferably a groove 134 inside the at least one driving mechanism 130) allows for accommodating the at least one second sealing element set 140, thereby sealing the secondary space 131 between the at least one driving mechanism 130 and the at least one insertion mechanism 110.

[0062] like Figure 1A As can be seen in the figure, the at least one second sealing element group 140 includes at least one second sealing element 141 (preferably a second gasket 141) and / or at least one second blocking mechanism 142: the at least one second blocking mechanism 142 is harder than the at least one second sealing element 141. The at least one second blocking mechanism 142 is configured to limit the full or partial displacement of the at least one second sealing element 141 in the secondary space 131, preferably to prevent the displacement of the at least one second sealing element 141 in the secondary space 131.

[0063] exist Figure 1A and 1B As can be seen in the figure, the secondary space 131 includes a first secondary volume 133 and a second secondary volume 132, the first secondary volume 133 includes the cavity 134 (preferably the groove 134), and the at least one second blocking mechanism 142 and the at least one second sealing element 141 are located in the first secondary volume 133. The at least one second blocking mechanism 142 is configured to limit (preferably block) the full or partial displacement of the at least one second sealing element 141 from the first secondary volume 133 to the second secondary volume 132.

[0064] In addition, the at least one insertion mechanism 110 includes a supporting surface 113, which is configured to enable the at least one second sealing element 141 to contact the at least one second blocking mechanism 142 when the at least one driving mechanism 130 is maintained in the at least one first position 101, so that when the at least one driving mechanism 130 is maintained in the at least one first position 101, the at least one second sealing element 141 can contact the at least one second blocking mechanism 142.

[0065] exist Figure 1A and 1B It can also be seen that the sealing device 100 includes a compensation mechanism 160, which is configured to seal the secondary space 131 between the at least one driving mechanism 130 and the at least one insertion mechanism 110 and / or compensate for the gap of the at least one retaining mechanism 150, so that when the at least one driving mechanism 130 is retained in the first position 101, the gap caused by the manufacturing tolerance of the at least one retaining mechanism 150 is compensated, thereby sealing the secondary space 131 between the at least one driving mechanism 130 and the at least one insertion mechanism 110.

[0066] The at least one first sealing element group 120 is configured to seal the main space 201, and is preferably located on the at least one insertion mechanism 110, between the intermediate component 210 and the at least one insertion mechanism 110, and includes at least one first sealing element 121 (preferably a first gasket 121) and / or at least one first blocking mechanism 122: the at least one first blocking mechanism 122 is harder than the at least one first sealing element 121.

[0067] As can be seen from the figure, compared with the at least one first blocking mechanism 122 and the at least one second blocking mechanism 142, the at least one first sealing element 121 and the at least one second sealing element are closer to each other, so that the at least one first sealing element and the at least one second sealing element 141 are the first components on the water penetration path.

[0068] The at least one first blocking mechanism 122 is further configured to limit the full or partial displacement of the at least one first sealing element 121 in the main space 201, preferably to block the displacement of the at least one first sealing element 121 in the main space 201. In practice, the main space 201 comprises a first main volume 203 and a second main volume 202, the first main volume 203 comprising the at least one first blocking mechanism 122 and the at least one first sealing element 121. The at least one first blocking mechanism 122 is configured to limit (preferably block) the full or partial displacement of the at least one first sealing element 121 from the first main volume 203 to the second main volume 202, thereby sealing the main space 201 at a high pressure, for example less than 1500 bar.

[0069] According to an embodiment, a support mechanism 112 included in the at least one insertion mechanism 110 is added to support the at least one first sealing element group 120, thereby strengthening the restriction of displacement of the at least one first sealing element group 120 under a high pressure of, for example, less than 1500 bar. In fact, the at least one first sealing element group 120 is arranged between the support mechanism 112 and the abutment mechanism 114.

[0070] Of course, the sealing device 100 allows sealing the watch 200 at a high pressure, for example less than 1500 bar, more specifically, sealing the main space 201 between the intermediate part 210 and the at least one insertion mechanism 110 and the secondary space 131 between the at least one drive mechanism 130 and the at least one insertion mechanism 110.
