Abstract (en)
[origin: EP1890204A1] The watch has a time base formed of a piezoelectric resonator (1) e.g. quartz resonator, and an oscillator circuit (2). An electric motor (5) drives needles (6). A circuit (4) controls the motor. A set of connection points supplies an oscillator circuit (2) of the base and the circuit (4). Another set of connection points controls the motor. The circuits (2, 4) are integrated in a single integrated circuit (7). The circuit (7) has a frequency divider (3) placed between an output of the circuit (2) and an input of the circuit (4) for providing signals at a frequency of controlling the motor.
