One aspect of the utility model relates to a watch dial comprising an autonomous lighting device, the autonomous lighting device (3) comprises the following functional elements: at least one light emitting source (4), an autonomous
power supply unit (21), and a
control unit (7) used for managing the operation of the at least one light emitting source (4), the dial (2a, 2b) is formed by a plurality of assemblies (9a, 9b) through stacked
layers (10, 11, 12, 13, 14), the plurality of
layers (10, 11, 12, 13, 14) are connected together via stacked
layers (10, 11, 12, 13, 14) and each comprise one or more functional elements of the autonomous lighting device (3).
