Isn't this just using the sun as a compass? You could easily just look at the position of the sun knowing what time it is, or use your hand and make a sun-dial.

Isn't this just using the sun as a compass? You could easily just look at the position of the sun knowing what time it is, or use your hand and make a sun-dial. I believe the watch is only there to tell us the time and cross reference that with the sun's position.
- Terr_ 4y agoYeah, the strategy only really involves (A) knowing the current time and (B) a protractor or a good sense of angles. Or in word-algorithm form: 1. When the sun rises that's usually at 6AM in the East, at 12AM noon it's usually towards the South, and when it sets that's usually 6PM in the west. (Valid for northern hemisphere only.) 2. Use the current time to linearly interpolate between those three values. 3. Once you know the heading of the sun, you can figure out which way is north.
- rosywoozlechan 4y agoRight, if you can see the sun and know the time of the day why do you need a watch for this.
