I'm 22, and I wear a wristwatch. I wear an expensive wristwatch, actually, that's solar powered, radio synchronized, has a barometer, etc. If I had a wristwatch that merely told the time, however, I might not bother.
I'm 21 and I usually wear a wristwatch. I wear an expensive wristwatch, actually. All it does is tell the time. It isn't solar powered, it doesn't synchronize with a server somewhere based on nuclear time, it doesn't even have a chronometer. If it had more features and did something other than tell the time, however, I might not bother.
