I'm 19, and I've worn a wristwatch for the last 10 years, at least. The one I currently have hasn't run down its battery for more than two years, and is comfortable and light enough that I never take it off. As a result, I'm often the only person in a group who knows what time it is.
I'm incredibly violent to things on my wrist. I whack it on door frames, tables, everything. It probably means I'm getting too close to things when I'm walking around, but I heal - watches don't. (yet?)
I'm 18, and have worn a wristwatch since I proved to my parents that I could tell time with an analog clock at the age of 4. I will admit that about 2% of my school wears one though.
