Measuring Barometric Pressure and Temperature

  1. Enter the Barometer/Temperature Mode.

  2. Entering the Barometer/Temperature Mode starts measurement, and displays the barometric pressure and temperature at your current location, and a barometric pressure graph.

    After you enter the Barometer/Temperature Mode, the watch takes readings about every five seconds for three minutes. After that, a measurement is taken about every two minutes.


    To re-trigger measurement, press (B).

    To return to the Timekeeping Mode, press (D).


The watch will automatically return to the Timekeeping Mode if you do not perform any operation in the Barometer/Temperature Mode for about one hour.

Measurement ranges are shown below. [- - -] will appear for the measured value if it is outside the allowable range.
Barometric pressure measurement: 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg)
Thermometer measurement: -10.0 °C to 60.0 °C (14.0 °F to 140.0 °F)
