Your analog watch can serve as an impromptu compass.
Point the hour hand towards the sun, then true south will be halfway between the hour hand and the 12-o'clock mark. Assuming you're in the northern hemisphere.
E.g. if it's around 2-o'clock, direct the hour hand towards the sun, and south will be in the 1-o'clock direction --- and therefore north towards the 7-o'clock direction.
Point the hour hand towards the sun, then true south will be halfway between the hour hand and the 12-o'clock mark.
Only if your watch shows solar time which is normally not the case.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
