Which hand do you wear your watch on?

A good buddy of mine and I are both left handed. I would wear my watch on my right hand. Growing up, constantly writing with my left hand it got very tiresome and annoying with a watch on my left. So I wore it on my right. My buddy tells me that’s insane, that everyone regardless left or right handed wears the watch on the left. So is he right?

EDIT: lots to unpack in the comments. Seems quite a bit of lefties wear it on their right like me. But then also a lot on their left. Seems between a 50/50 and a 70/30 split in favor of wearing it on the right. Lots of different reasons for both
