I have 4, I think, but I regularly wear just one. Two are dressier watches, one from my parents, that I always forget about - mostly because they're gold and I rarely wear gold. The third is a gear watch, Ironman brand I think, which does all the split laps and countdowns and all that jazz, which I used to use a lot when I was doing long-distance walking training. The last is a Citizen Ecodrive in silver with a white face which my husband got me for Christmas a couple years ago and I wear mostly every day. I do take it off when I work on my laptop because it is uncomfortable when I type (the same reason I rarely wear bracelets and bangles).
People who constantly check the time on their phones annoy me, for some unexplained reason. It just somehow seems ruder than discreetly glancing at a watch or a clock on the wall.
