Never understood why it's the norm for guys to wear watches on their left hand, and girls are supposed to wear them on the right hand. Date Posted: Apr 2, 2009 #2. Not gay. feminine.
men wear their wedding rings or watches on their left hand or arm. I was always told that it's done like that so it doesn't get in the way of their dominant hand. The dominant hand (for most people this is the right hand) is involved in many more activities and therefore is at greater risk of damaging the watch.
