That's my reason too lenkid...and also because I am realy uncoordinated with my left hand so I can't use my left hand to put the watch on my right hand...
I never take off my watch... I'm weird, I just never do... Well, I do sometimes take it off when I'm in the shower, lol. I even sleep with it on, I just love my watch to peices! ^_^ lol... And I wear it on my left....
I've always worn it on the left wrist because I'm right handed...they say that's "correct" or "normal" because then you can look at your watch while doing other things with your more often used hand.
