Abstract (en)
The dial has a ceramic substrate (1) whose outer surface has two enamel layers (3) and inner surface has an adhesive film (5). A thick metallic layer (7) is deposited on the film, to fix a steady-pin (9). A head (11) of the pin is fixed on the layer (7), by sticking, welding or soldering. The inner surface has a cylindrical housing to position the steady-pin. An independent claim is also included for a method of manufacturing an enameled dial with a steady-pin.
