First Claim
Patent Images
1. An analogue timepiece for indicating an atmospheric pressure variation comprising:
- at least two hands (2,
3) for providing time information,a watch movement (12) for driving said hands, said watch movement including an electronic control means for controlling the watch movement for driving said hands,conversion means (30) electrically connected to said electronic control means, anda pressure sensor (13, 13a) for measuring the atmospheric pressure variation and providing to said conversion means indications of said atmospheric pressure variation,wherein one of the hands (2,
3) is driven by the movement (12) to indicate said measured pressure variation in response to pressure information provided by said conversion means to said electronic control means, while at the same time another one of said hands (3,
2) is driven by the movement to indicate a weather forecast which is a function of said measured variation and which is determined by said electronic control means.

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.
