I'm right handed and wear my watch on my left. My hubby is left handed and wears his on right.
I think its mainly to do with when you had to wind watches up, you had to wear the watch on the opposite wrist to you one you used to wind it up with.
Maybe the people that wear the watch on their working wrist were ahead of their time and had advanced watches that you didn't have to wind up!
I think this may be the truth!!! especially the winding one !!!
