As in the Northern Hemisphere, you should take off your watch and lay it flat in your hand when you're in a location where you're able to see the sun. The key difference between the Northern and Southern Hemispheres when it comes to using a watch as a compass is that in the Southern Hemisphere, it's the 12 o'clock mark, rather than the hour hand that you must line up with the sun. Reversing the orientation of your watch relative to the sun allows you to account for the difference in the sun's orientation between the two hemispheres. If you're having a difficult time getting a bead on the sun, you can use the same shadow trick as in the Northern Hemisphere to ensure your 12 o'clock mark is precisely lined up. The exact middle of the angle between the 12 o'clock mark and the hour hand on your watch marks North, while the point directly across the face of the watch from it marks South.  For example, if it's 9 o'clock in the morning and we line the 12 o'clock mark on our watch up with the sun, the midpoint between the 10 and 11 o'clock markings is North and the point across from this (between the 4 and 5 o'clock markings) is South. If your watch is set to Daylight Saving Time, use the 1 o'clock marking on your watch as your benchmark, rather than the 12 o'clock mark, as you would in the Northern Hemisphere.
احمل الساعة أفقيًا. وجه علامة الساعة الثانية عشرة في اتجاه الشمس. نصف الزاوية بين عقرب الساعات وعلامة الساعة الثانية عشرة لإيجاد الشمال.
