How to use the watch as a compass (Northern Hemisphere, for example)
The approximate direction can be determined by comparing the position of the hour hand with respect to the Sun. Note that these determinations are approximate as discrepancies occur between different latitudes and seasons.
Position the watch horizontally and align the hour hand of the watch with the position of the Sun.
The midpoint between the alignment of the Sun with the hour hand, and the 12 o’clock position of the dial, indicates approximately South .
If you position the rotary ring so that it points south, you can read other approximate directions from the compass.
