Barometric Pressure
Measurement
Q1
Following a relative barometric
pressure reading, the watch’s
second hand points to 9 o’clock.
The second hand will move to 9 o’clock if a
reading is outside the allowable barometric
pressure measurement range (260 hPa to
1,100 hPa (7.65 inHg to 32.45 inHg)). If [ERR]
appears on the display, there may be a
problem with the sensor.
