Find out North without navigational survival gear.

If you need the help of a compass but you don't have one, you can use an analog watch to do that. Point the hour (short) hand at the sun and draw two imaginary lines between it and the 12 o'clock point. You will create an angle between the two lines. Draw an imaginary straight line bisecting the angle. The line point away from the sun is north, because the sun always goes to set in the west direction.

Disclaimer: telling time by sun doesn't work as effectively when you are too far up north or south.
