Description

WATCH DIAL WITH DECORATIVE ELEMENTS [0001] The present invention relates generally to the field of watchmaking, more particularly to the field of the manufacture of watch components, such as for example watch dials, as well as the field of jewelry. [0002] Watch dials are known in the prior art. For example, document CH711917 discloses a watch dial with an inflatable pocket and a material capable of reflecting different visible wavelengths depending on a stress applied by a device. [0003] However, it is desirable to improve the aesthetics, to cause surprising or moving visual effects, and/or to improve the information available on the dial, in particular their dynamic effect, in order for example to notify the user of a particular function with decorative elements. This may be for example a passage of time, day, month, a new moon phase, or any other information, or even a particular gesture of the user, and also to simplify the manufacture and implementation thereof. [0004] The present invention thus aims to propose a new construction of watch components, in particular watch dials. [0005] In a first aspect, the invention relates to a dial for a timepiece or piece of jewelry, comprising: - at least one first decorative element movable between a first position and a second position, - at least one second decorative element movable between a third and a fourth position, - an activation mechanism arranged integrally with the at least one first decorative element to move it from the first position to the second position, or vice versa, and - a transmission mechanism, with at least one elastic element such as a membrane, integral with the first decorative element and the second decorative element, so as to transmit the movement of the activation mechanism of the first decorative element to the second decorative element to move it from the third to the fourth position, or vice versa. [0006] This makes it possible to propose a watch dial or display mechanism with improved aesthetics and simplified operation, while making it possible to display relevant information or providing an interface to the user to display information or play with it. In addition, this makes it possible to ensure the transmission of the initial movement with modulation, in particular by playing on the stiffness of the elastic element, so as to adjust the movement of the other first decorative element. [0007] The invention may also be defined according to the following characteristics, taken individually or in combination. [0008] Advantageously, the dial further comprises at least one third decorative element and the first decorative element and/or the second decorative element at least partially covers the at least one third decorative element in one of the four positions. [0009] Advantageously, the elastic element comprises a portion attached to or secured to a frame (of a watch, timepiece or jewelry). [0010] Advantageously, the at least one first decorative element comprises a counterform, preferably a stepped counterform, of the at least one second decorative element or of the at least one third decorative element. [001 1] This makes it possible to ensure good coverage between the at least one first decorative element and the at least one second decorative element. [0012] Advantageously, the counterform has an overlap or covering of the at least one second decorative element or of the at least one third decorative element. [0013] Advantageously, the counterform is complementary to the shape of the at least one second decorative element or of the at least one third decorative element. [0014] Advantageously, the counterform of each of the at least one first decorative element is complementary to the shape of each of the at least one second adjacent decorative element or of each of the at least one third adjacent decorative element. [0015] Advantageously, the at least one elastic element supports the at least one first decorative element, the at least one second decorative element and/or the at least one third decorative element. [0016] Advantageously, the at least one elastic element is a membrane or a plurality of membranes. [0017] Advantageously, the at least one elastic element is a spring or a plurality of springs. [0018] This makes it possible to ensure an elastic return of the first decorative elements to their initial position or to apply a return force. [0019] Advantageously, the at least one first decorative element, the at least one second decorative element and/or the at least one third decorative element is fixed. [0020] Advantageously, the at least one third decorative element is mobile. [0021] This improves aesthetics while optimizing the presentation of information. [0022] Advantageously, the at least one first decorative element, the at least one second decorative element or the at least one third element decor includes a fluorescent, phosphorescent, luminescent or visible material in dim light or darkness, such as luminesc
