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?

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.
