  • Patent number: 11971686
    Abstract: A dial, and timepiece including the dial, including a mother-of-pearl wafer partially covering a support member, and a decorative element arranged on a reverse of the wafer, the decorative element being visible on an obverse of the wafer when subjected to a stimulus and invisible on the obverse of the wafer in the absence of the stimulus. The decorative element has a first empty area on a reverse of the wafer, and a second empty area on the obverse of the wafer, facing the first empty area. A colour compensation layer is deposited on the first empty area or the second empty area, the colour being selected such that the difference in colour ?E in the CIE Lab colour space between the colour compensation layer and the decorative element in the absence of said stimulus, perceived by a user observing the obverse of the wafer, is less than 3.

  • Patent number: 6113726
    Abstract: A method by which an elastomer is applied to a model (1) with relief marks to be reproduced. The purpose of the elastomer once set is to form a mold membrane (14) and incorporate within its own material the shape of the marks on the model. The mold membrane is then separated from the model and filled with a setting material, and the mold membrane is applied to a support in order to transfer the marks after preliminary pasting.
