Depends what kind of mood I'm in really.
If I want to get the ladies, I obviously choose a "bad guy" watch to suit the image.
However I'll also bring along a backup watch. Sometimes when I tire of girls practically (who am I kidding, literally) throwing themselves at me, I will go go to the bathroom and change personas. For this I like my flower bezel Hello Kitty watch to let them know I'm not interested.
If I'm going to a business meeting I always wear the watch that shows how serious I am.
