Navigating by sun’s position: The direction will be accurate if you are using true local time without any
adjustment for daylight savings time. The further you are from the equator, the more accurate this method
will be.
In the northern hemisphere, bisect the angle between the hour hand and the 12 o'clock mark and set the
bezel’s S (30s) indicator to that point. Hold the watch horizontal and point the hour hand at the sun; the
bezel’s N indicator will be pointing North. If there is any doubt as to which end of the line is north,
remember that the sun rises in the east, sets in the west, and is due south at noon. The sun is in the east
before noon and in the west after noon, so set the bezel’s S (30s) indicator to the left of 12 in the AM and
to the right of 12 in the PM.
In the southern hemisphere, point 12 o’clock at the sun instead of the hour hand, the midway point between
the hour hand and 12 o’clock will be the North/South line.

*Note: If your watch is set for Daylight Savings Time instead of Standard Time, use the midway
point between the hour hand and 1 o'clock to determine the north-south line.
