  • 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: 11927922
    Abstract: A coiling limitation device for a timepiece barrel includes at least one non-return notch arranged to cooperate with a sliding flange of the spring of the barrel, which is integrated in a watch including a resonator cooperating with an escapement mechanism. This device includes an acoustic device for the acoustic monitoring of the coiling of the barrel of a watch positioned on a receptacle included by the device, which acoustic devices are arranged to identify a click noise during each start of cooperation between the sliding flange and a notch. The device includes piloting devices arranged to stop the coiling of the barrel at the instant of the perception of the click noise or the repetition of the click noise.

  • Patent number: 11640140
    Abstract: A process for producing a metal alloy balance wheel by molding includes a) making a mold in the negative shape of the balance wheel; b) obtaining a metal alloy that has a thermal expansion coefficient of less than 25 ppm/° C. and is able to be in an at least partly amorphous state when it is heated to a temperature between its glass transition temperature and its crystallization temperature; c) putting the metal alloy into the mold, the metal alloy being heated to a temperature between its glass transition temperature and its crystallization temperature so as to be hot-molded and to form a balance wheel; d) cooling the metal alloy to obtain a balance wheel made of the metal alloy; and e) releasing the balance wheel obtained in step d) from its mold. The process also includes a step for over-molding flexible centering components in the hub.
