Module No. 5678

Checking the Current Barometric Pressure

  1. Enter the Barometer Mode.

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

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


    To retrigger measurement, press (A).

    To return to the Timekeeping Mode, hold down (B) for at least two seconds.


If the hour and/or minute hand is located over the digital display when you perform a barometric pressure measurement, the hands will temporarily shift to 4 o’clock or 8 o’clock to allow easier reading of measurement values. The hands will unshift to their normal positions after about three seconds.

When you enter the Barometer Mode, the second hand indicates either timekeeping seconds, or the differential between barometer measurements (whichever was indicated the last time you were in the Barometer Mode).
You can toggle between the two second hand functions by pressing (D).

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

The measurement range is 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg) (1 hPa (0.05 inHg) units). [- - -] will appear for the measured value if it is outside the allowable range.
