Description

The present invention relates to a method for manufacturing a clock face, the clock face comprising decoration including a three-dimensional representation of a landscape. This invention further relates to such dials and watches equipped with such dials. To highlight conventional display components, some watches feature dials with three-dimensional decorations on their visible surfaces, giving the watch a distinctive character. This type of decoration typically features geometric reliefs. This type of dial is typically manufactured using a process that includes the steps of processing a dial base material such as copper, iron or aluminum alloy, polymer, stone, ceramic, or any other material known to those skilled in the art, in order to obtain the three-dimensional shape, followed by polishing, enameling, and/or coloring steps. However, these processes remain insufficient in light of increasingly stringent requirements in terms of the aesthetic appearance of the dial and the potential presence of defects or burrs on these dials after the polishing and coloring steps. Furthermore, the decorative possibilities offered by existing processes are limited to a select few older and well-known processes, making it impossible to manufacture dials with original decorations. Therefore, in this context, it is necessary to find solutions to improve upon prior art. A general object of the present invention is to provide an improved and simplified solution for manufacturing aesthetically pleasing dials, including three-dimensional decorations, which does not contain all or some of the drawbacks of the prior art. For this purpose, the present invention relates to a method for manufacturing a clock face having a visible surface having a small surface area, wherein the surface has a three-dimensional representation of a landscape, in particular a topographic map of the landscape, and this method is A step of manufacturing a blank for a dial, including a top surface having a three-dimensional structure related to the three-dimensional representation of the landscape, the blank manufacturing step including a substep of generating topographic data for constructing the three-dimensional structure on the top surface, A step of processing the surface of the three-dimensional structure on the upper surface of the blank, wherein at least one visual feature of the surface is modified to obtain the three-dimensional representation. To obtain the aforementioned dial, the process includes the step of finishing the blank. In other embodiments, The generating substep includes a phase of acquiring the terrain structure data by processing raw terrain data related to the landscape, the processing operation being performed by a terrain structure data generation algorithm executed by a controller of the system that generates such data, and the acquiring phase includes performing calculations to determine the terrain structure data as a function of the dimensions of the upper surface of the blank, the basic shape of the surface, the properties of the material of the substrate constituting the blank, and the visual features of the three-dimensional structure of the upper surface constituting the three-dimensional representation of the landscape that are perceived by an observer. The acquisition phase involves performing operations to correct the values of the raw terrain data, thereby causing variations in the dimensions of the different zones of the structure, namely flat zones, uplifted zones, and/or recessed zones. The manufacturing step includes a substep of manufacturing the three-dimensional structure on the upper surface of the blank, the substep includes a phase of patterning the upper surface of the blank based on acquired terrain structure data, The processing step includes a substep of modifying the surface condition of all or part of the three-dimensional structure.
