Abstract (en)
[origin: EP1538493A1] The dial has a ceramic upper unit (1a) having enamel layers (3) on its outer surface. A ceramic lower unit (1b) is provided with a hole (2) to receive a steady-pin (9) by sticking and/or pressing, before assembling the two units by a glue joint (4) and a peripheral weld (6). The two units have same dimensions and have same thickness of about 0.4 to 0.5 millimeters. An independent claim is also included for a method of manufacturing an enameled dial with pressed steady-pin.
