ABSTRACT:
An analogue timepiece capable of indicting a pressure variation, such as that of atmospheric pressure, comprises at least two hands (2, 3) for providing time information, a watch movement (12) for driving the hands and a pressure sensor (13, 13a) for measuring the atmospheric pressure variation. One of the hands (2, 3) indicates the measured pressure variation while one of the others of said hands (3, 3) indicates at the same time a weather forecast as a function of the variation.
