I've never really figured out why wear a wristwatch. I think I last had one when I was in elementary school, early 90's. By high school I had dropped the habit.

I don't care about glamorous shiny and expensive things, so that's no reason to wear a watch, really.

I rarely need to check the time and whenever I do, I can usually just see it somewhere: the city is full of clocks, especially the places where you might want to know the time, like tram stops and subway stations.

When I'm at work my computer conveniently tells me the time so that I can appear at a meeting roughly on time.

If I really, really need to have the time then I can use my cellphone. Well, I don't have my cellphone with me all the time, so I can't always do that either. Especially if I'm going alone and have no rendezvous coming up, I don't have it.

If I'm cycling around on a summer day, that's usually without the watch I don't have and without the cellphone I don't want to carry with me, so I can usually tell when it will soon be the evening and to turn my heading back to home.

A few times I've just asked for the time. That's quite as low-tech as it goes.
