In Meteo mode, the hands are superimposed to indicate the weather trend. The advantage of the barometer is that it enables the relative atmospheric pressure to be displayed. This relative pressure is displayed in hectopascals.

Changes in the weather are related to variations in atmospheric pressure. When the atmospheric pressure rises, the sky clears. The area is then referred to as one of "high pressure", or an "anticyclone". When the atmospheric pressure falls, the sky clouds over. The area is then referred to as one of "low pressure" or a "depression".

• The T-Touch Connect Solar watch measures these pressure variations and indicates the weather trend with the hands, which can adopt the following 7 positions according to the weather developments:

The T-Touch Connect Solar program takes account of atmospheric pressure variation over the last 6 hours to calculate the trend to indicate. In addition, the pressure variation caused by a rapid change in altitude is detected by the watch and compensated for automatically. It therefore has only a minimal influence on the barometric trend. The T-Touch Connect Solar’s digital display shows the absolute and relative atmospheric pressure values in hectopascals [hPa]. Absolute atmospheric pressure is the actual pressure at the time and place the measurement is taken, and cannot be modified. Relative pressure is a value relating to sea level, based on the local absolute atmospheric pressure. Barometers and weather maps show relative pressure values. The relative pressure value depends on the climate zone set, and can be preset on the watch. The relative pressure presetting is related to the altitude.
