direction value will not be accurate if the watch is not oriented correctly.

The direction value shows the direction that the 12 o’clock position of the
watch is pointing as an angle value. See “Direction Values” for details.

After you take a direction and temperature reading in the Timekeeping
Mode, temperature readings continue to be performed every two minutes.

See “Temperature and Direction Reading Precautions” and “Digital
Compass Precautions” for other important information about taking
direction and temperature readings.
