All you'll need for this survival trick is an analog (not digital) clock or watch that's set to the correct time and a clear view of the sun. See Step 1 below to get started.
In the Northern Hemisphere
Hold the watch horizontally. This trick can be used anywhere in the Northern Hemisphere during the day, when the sun is visible. Lay the watch flat and face-up in your palm so that its face is parallel with the ground.
Point the hour hand in the direction of the sun. Turn the watch, your hand, or your entire body so that the hour hand of your watch is pointing directly at the sun. The time on the watch doesn't matter, as long as it's accurate.
If you're having a hard time lining the hour hand up with the sun exactly, you may want to use a narrow object's shadow to help you. Stick a twig or narrow post into the ground so that the shadow it casts is clearly visible. Then, line the shadow up with the hour hand of your watch. An object's shadow is cast away from the sun, so lining your hour hand up with a narrow shadow is essentially the same as lining it up with the sun itself.
