A light-emitting clock has a case, a dial, a light-emitting mechanism, a movement and a plurality of hands. The case has a front cover, a back cover and a washer. The front cover is coupled to the back cover. The washer is disposed between the front cover and the back cover. The dial is disposed between the washer and the back cover. The light-emitting mechanism has a switch, a power unit electrically connected to the switch, and at least one lamp strip electrically connected to the switch. The switch and the power unit are disposed on the back cover. The lamp strip is annularly disposed at the washer. A light-emitting surface of the lamp strip at least faces the rim of the dial. The movement is disposed on the back cover. The hands are coupled to the movement and correspond in position to one side of the dial.

A watchmaking gasket, in particular a watch glass gasket for a timepiece, includes a polymer matrix charged with phosphorescent and/or fluorescent pigments.

A horology component (1) for a timepiece, including a first portion (10) and a second portion (20), the first portion (10) comprising one part that is at least partially transparent and at least partially superposed on top of the second portion (20), this second portion (20) taking the form of a massive portion comprising a material capable of emitting at least one emission light wave if excited by at least one excitation light wave, and the at least partially transparent part of the first portion allowing an emission light wave emitted by the second portion (20) to be transmitted at least partially toward the outside of the horology component so that the horology component exhibits at least a first appearance by day and at least one different second appearance by night where the first portion (10) is backlit by an emission light wave emitted by the second portion (20).

A device for illuminating luminescent watch displays containing luminophore material, including a case arranged to receive at least one receptacle for receiving at least one watch, the device including a illuminating device arranged to light up the displays of each said watch. The illuminating device include a control device and a time base, and at least one light source capable of exciting said luminophore material for a pre-determined charge time, or corresponding to a wearing duration chosen by the user via a control device included in the device, and watch self-winding device, including at least one such illumination device, and universal device for winding and setting the hands of a watch, including such a watch self-winding device.

A gaseous tritium light source (GTLS), which has a hermetically sealed outer sleeve made of glass, more particularly borosilicate glass. A high durability and lighting intensity is produced due to the fact that at least some sections of the outer sleeve have an outer coating applied directly to the outer surface of the outer sleeve serving as a reflective layer made of a metal, wherein the outer coating has an epitaxial structure and wherein the metal has a reflectance of >70% for visible light.
