Who made it compulsory or normal to wear watches on the left wrist? And why do we think those who wear on the right are mad?

It's not a compulsory boo.. But most of us (all over the world) are right handed...
And they said tat the lesser the wrist movement, the lesser the watch prone to damage


I myself is a right handed person but I wore it on my right wrist coz my left hand is allergic to the straps...

lol
interesting.
each time I wear it on my right hand, I jst feel someone is laughing at me.
