Was there an alternative adjective to “clockwise” other than “the rotation you take around left hand”?
Also, how did all watch companies around the world agree on what the direction of “clockwise” is?

Well, clocks are just mechanical sundials. Before clockwise, there was sunwise (or deosil), and clocks’ movements are based off of the movement of a shadow across a sundial.
does that mean that “clockwise” in the southern hemisphere is backwards?
Yes, when you are in the northern hemisphere, a sundial shadow falls to the north of the gnomon (the thing that makes a shadow). This makes the shadow move from the northwest to north to northeast over a day, which is clockwise. In the southern hemisphere, the shadow from the gnomon falls to the south, so it starts in the southwest and moves to the south and then southeast, which is anticlockwise.
The most obvious way to see this is the photo of the sundial in Perth, where the hours run anticlockwise.

Because of the Coriolis effect (/j)
No, because the earth is still rotating the same direction in the southern hemisphere
I read this article and I’m more confused now lol

EDIT: The last sentience sums it up well tho:
Well well, learn something new everyday.
Pretty weird to think about. And about them having to either face their relevant poles or the equator for them to work equivalently
