Abstract:
1. A timepiece fitted with a glass having an inside face and an outside face to the timepiece and a lighting device comprising at least one light-emitting diode producing an ultraviolet, infrared or blue light to illuminate at least one zone integrating fluorescent and/or phosphorescent pigments of an indicator element visible through the glass, wherein the light emitted by the diode is directed onto the periphery of the glass forming a waveguide capable of diffusing the light, wherein means for diffusing the ultraviolet, infrared or blue light from the glass towards the interior of the timepiece are arranged in the path of said light, wherein the means for diffusing the ultraviolet, blue or infrared light are arranged in the form of at least one ring so as not to obstruct the visibility of the fluorescent and/or phosphorescent zones of the indicator element.
