Venexx makes this watch that sprays perfume.  You can fill it with perfume or cologne and when you don’t feel as fresh as you would like.  Spray.  It would also be great if you have a stinky person next to you. Ever been stuck on a plane next to someone who smells? Not a problem anymore. Although TSA might have a fit if you try to go through security with it on. If I had this watch I could go for a week without having to take a shower.  I am pretty sure James Bond has a watch like this except it is filled with acid or poison and not cologne.
