Basic information of the compass

Accuracy assurance temperature

–4 °F (–20 °C) to 104 °F (40 °C)

Assured accuracy

±10°

• The accuracy is guaranteed when temperature is constant after 2 point correction.

About the regions where the compass function may be hard to use

In the patterned regions on the next page, the compass accuracy of the watch may 

not be maintained due to the characteristics of the geomagnetic field. When using 

the compass function of the watch, check the region.
