In the absence of a compass, there is a fairly precise method of orientation, which involves the use of a common classic clock with hands.

Instructions for Use:

  1. place the watch horizontally;
  2. point the hour hand towards the sun;
  3. The midpoint between the alignment of the sun with the hour hand and the 12 o’clock position on the dial indicates approximately south.

Obviously, the clock must be adjusted to solar time and not summer time, respecting the time zone of the place of observation. For a more precise orientation, a small adjustment can also be made according to how far we are moved east or west of the meridian relative to our time zone. If we are at the centre, no correction will be needed.
