Yes, and quite easily too provided the wristwatch shows accurate local time. The method of finding directions: If you hold the watch vertically with its side straight up and down at 12 o’clock noon when both, the hour and minute hands converge and point their tips towards the Sun, they are pointing due south on the ground. Hence the direction at 3 o’clock is due west, at 9 o’clock due east and at 6 o’clock due north. In case you want to ascertain directions before or after the noon, hold the watch sideways with the hour hand pointed towards the Sun, Now due South will be pointed by the imaginary line exactly bisecting the angle between the hour hand and the 12 o’clock mark.

Suppose your watch shows 10 AM. Hence due south lies exactly in the direction of 11 o’clock, in the
same manner, at 6 o’clock in the evening 3 o’clock mark lying between 6 o’clock and 12 o’clock will be due south, Once south is ascertained, marking out other directions is not difficult. However, following riders should be kept in mind:

1. The above method will hold good in the northern hemisphere, and
2. The directions so ascertained will be geographic and not those that can be ascertained with magnetic compass.
