- How do I find north using a watch? 2 answers
In Treasure Of Khan by Clive Cussler, the main protagonist is lost in a desert and uses his watch to determine directions, here is the quote :
An old survival trick, he knew that south must be halfway between the hour hand and twelve o'clock if he was standing in the Northern Hemisphere.
I didn't quite understood it. Is this a real trick ? Is there a name for it ? How does it work ?
