摘要: The invention concerns an electronic time-piece having a barometric indicator, indicating, for example, trends. comprises, in addition to the reference oscillator determining time, measurement associated with transducer exposed ambient air. A counter measures variations of frequency due fluctuations atmospheric pressure, and circuit controls, from predetermined detection thresholds, indication trend on display device time-piece.
