HOW TO USE THE COMPASS DIRECTIONAL RING

If your watch is equipped with a compass directional ring, it gives approximate compass readings. Locate the sun and then follow these steps:

1. Point the hour hand at the sun (see diagram).

2. WHEN IN A.M. TIME - Rotate the compass directional ring until S (South) is past the hour hand and halfway between the hour hand and 12:00. 
WHEN IN P.M. TIME - Rotate the compass directional ring until S (South) is before the hour hand and halfway between the hour hand and 12:00.

Adjust the compass directional ring every hour to reflect changes in the sun's position. When reading the compass directional ring, make sure the hour hand is always pointed towards the sun. When the hour hand is at 12:00 noon, S (South) should also be at 12:00.
