How to find your bearings with a watch

So, if I was to ask you where north was you'd either point in the rather direction of north, get your compass out or even open Google maps on your mobile phone, but there is another way to find north. This technique uses the sun and your watch (Analogue, not Digital) and it isn't very hard to do. 
So you're lost in the middle of a field with just a map, a set of bearings and a watch. What do you do. well you use you're watch like a compass and use it to work out your rough bearings. I'm going to tell you how to do this as if you were standing in the united kingdom, so you'd have to take in to account that it's in the Northern hemisphere, so the sun moves from east to west via south rather than north like in the southern hemisphere.
So firstly you're watch must be set to local time, so for the United kingdom, It would be Greenwich mean time or +/- 0 hours. with this you must also take in to account, whether or not it is daylight savings at the time. 
Next, you must hold your watch flat in the palm of your hand and point the hour hand towards the sun. 
After this, bisect the angle between 12 and the hour hand if it's Greenwich Mean Time (winter months) and 1 and the hour hand if British Summer Time (summer months). The Diameter line running through the watch face and the half way point of the angle should result in pointing towards north/south. 
The end of the line which is furthest away from the sun, will point towards true north.

To use this method to find bearings, you just need to imagine that the watch face has bearings running around the outside edge just like on a compass face. The degree angle for a full circle or watch face will equal 360, so if every number's central point is equal distance away from each other around the watch face, each distance should equal 33.3 degrees. Next time, I will write about how to make a para-cord bracelet watch.
