Are you sure that your wrist watch shows the right time always?

I can not stand to be late. Because of that, I always leave early and set all my clocks at least 5 minutes fast. I don't really look at my watch to synchronize it with other clocks. Rather, I am pretty much surrounded with clocks that at some point, I am going to notice if my watch is significantly off from those clocks around me. I have a pretty reliable watch and have a battery that lasts a good year. :) And I just replaced it a couple of months ago...so I think I am set for a while longer. :D

I actually do not own a wrist watch, I cannot remember the last time that I wore one..Many many years ago though..
