A trick we had to learn in Labrador, 40 years ago, where sun compasses were used, because of the severe magnetic deviations around the iron formations: make a fist with your thumb folded over the top and thumb nail facing upward. Take your knife blade and hold it upright, with the point sitting on your thumb nail. Slowly turn the blade until the shadow made on your thumb nail by the blade is the *thinest*. The blade, with aligned shadow, is *pointing* toward the sun. This will work on even very overcast days. Then make the conversion for the analog watch.
