Abstract

The watch includes a decorative element comprising a mobile ring (8) having an eccentric mass. The ring is able to turn through 360 degrees on a set of ball bearings. The bearings are arranged concentrically within the watch casing (2). They support the ring so that its upper surface is visible to the outside.

Description

  
 



   DESCRIPTION



   The present invention relates to a watch provided with at least one mobile decorative element.



   Watches are already known which include mobile decorative elements. It can be a figurine which is driven in an oscillating movement under the action for example of the second wheel to which it is mechanically linked, or alternatively brilliants moving separately by sliding randomly in a space included between the watch glass and an internal wall parallel to it, as described in patent CH 609,517.



   Also known, in particular from patents FR 1 046 943 and BE 533 232, watches provided with movable elements, for example integral with the rotor, therefore not free, which are not decorative but which serve as benchmarks for the production of a Game.



   The object of this invention is to provide a watch in which the movement of at least one decorative element gives the whole an aesthetic effect different from that of known watches, in particular that covered by the aforementioned Swiss patent.



   The watch according to the invention, aiming to achieve the above goal, is characterized by the fact that it comprises at least one decoration ring having an eccentric mass and mounted freely rotating on 360C by its periphery on a ball bearing, this ball bearing being arranged concentrically inside the watch case, and the whole being arranged so that at least part of the upper surface of the decoration ring is visible from the outside.



   The mobile decoration element can be engraved, guilloche, provided with brilliants or any other type of decoration (hologram, colored surface coating, mother-of-pearl, etc.).



   The appended drawing illustrates schematically and by way of example an embodiment of the watch according to the invention.



   Figure 1 is a plan view.



   FIG. 2 is a partial view in cross section of the embodiment according to FIG. 1.



   The watch illustrated in Figures 1 and 2 includes a
 case back 1, a middle-bezel 2 screwed onto said case back, and a glass
 3. The bezel 2 has an inner rim in which are
 machined housings 4 intended to receive brilliants 5
 forming a fixed outer crown of brilliants.



   In the center of the watch is housed a case or cap 6
 containing the mechanical or electronic driving means
 needles 7.



   Finally, between the functional box 6 and the crown
 fixed external of brilliants 5 is arranged an element of
 mobile decoration consisting of a ring 8 mounted tower
 free freely by its internal periphery on a bearing with
 balls 9, itself mounted on an intermediate piece 10. This
 ring 8 is provided with a counterweight (not shown) or
 any other means intended to create an imbalance, so that
 that any movement of the watch tends to cause said
 ring in a free rotation over 360 ". As illustrated on the
   figurel, ring 8 can be fitted over its entire circumference
 diamonds 11 fixed in housings 12 and thus forming
 a second mobile internal crown of brilliants, concentrated
 than at the first fixed crown of brilliants 5.

 

   The aesthetic effect created by the relative rotation of the two
 crowns of brilliants 5 and 11 respectively is original and
 gives the watch thus decorated a commercial added value
 ciale. On the other hand, one or more other movable rings
 identical or not to the ring 8 can be mounted rotating
 freely over 360 "in the same way as said ring 8,
 concentrically or eccentrically to it. Well in
 stretched, the rotating decorative element may have other
 types of decorations, as mentioned above, or
 itself present a figurative or decorative form. By
  brilliant, we mean here and throughout the description
 tion, all types of stones, whether or not cut, precious or not,
 as well as natural pearls or not, precious or not.
