Abstract (en)
The timepiece has a case (12) fitted with a dial (28) and including an electronic control circuit (22) driving an analogue display device (24). The dial includes a main body (48) in the form of a plate made of silicon. The electronic control circuit includes a time base circuit formed by a reference oscillator (34) and a control unit (36) e.g. microcontroller, which is etched in the main body of the dial. The time base circuit and a micro electromechanical system are etched in the main body. The dial comprises raised indices (64) on its top face which includes a metallic coating.
