Every Watch a Compass

It is not generally known that a watch is a first-class compass, though it can only be effectively used when the sun is shining, according to a writer in Pearson's London Weekly. Point the hour hand to the sun, and south is then just half-way between the hour and the figure 12 on the watch. If, for example, it is four o'clock, the figure two on the watch is exactly south; or if it is eight o'clock, then ten on the watch is south.
