How to turn a watch into a compass at 09:30

The sun’s position on the compass varies with time of day, as do the positions of your watch’s hands: By combining the two equations, you can solve for direction. Just move your arm so your watch’s hour hand points to the sun. Halfway between the hour hand and the number 12 is south. (The trick doesn’t work at high noon, for obvious reasons—go have a gunfight and try again later.)
