Abstract (en)
The watch has a case (12) with an electronic control circuit (14) and analog/digital display units (16). The circuit, in an active operation mode of the watch, controls the display of the current hour. The circuit, in a standby operation mode of the watch, controls the stop of the units (16). The circuit triggers the passage from one mode to another based on a signal produced by an accelerometer (30) placed in the case. The accelerometer has pins for measuring the acceleration undergone by the watch, so that the circuit can determine if the watch is carried, in order to pass into active mode. The analog/digital display units (16) are supplied with electric power by an accumulator/battery (18). The accelerometer (30) has a microstructure formed by micromachining in a plate made of crystalline material.
