Here's a great way to use your watch as a compass. You will need a watch with hands and a view of the sun. Instructions are for the Northern hemisphere - reverse for Southern Start by pointing the small hand (hour hand) at the sun. It might be easier to take the watch off of your wrist. Now South is halfway between the hour hand and 12:00. For example, if the hour hand is pointing at 3:00, then South is at 1:30. The trick is the remember that morning hours have South between before noon. Afternoon mesurements will be on the hours after noon. Supppose it is 6:00. If 6:00 AM, then South is at 9:00 AM. But, if it is 6:00 PM then South is at 3:00 PM. Let's say it is 8:00 PM. Where is South on the watch face? South is a 4:00. Don't just use the side that is closest! Personally, I have had days when this little bit of information would have saved me a lot of time and aggravation.
