Um, I wear one. An analog Swatch. But it's colourful to accentuate my childish side. I know a hell of a lot of people that do. And those that don't are constantly asking us that do what time it is.
It's the quickest way to tell time.
It looks good (it is technically jewlery).
It can have a lot of other funtions than to tell time.
I'm used to it, it would feel weird not to wear one.
OP, are you serious?? How can you not wear a watch, I've never understood that. I'm not trying to question your opinion, I'm just curious.
