Personally, I tend to throw on a watch whenever I'm out of the house. Usually, it's to run a errand or to grab some food so I like to time how long it takes for me to get back home. In that case, a diving bezel to track elapsed minutes or even better, a digital stopwatch function for more precision.
I know chronographs can do the same thing, but I don't like to leave the chronograph running for over 30 mins when I'm not really gonna be looking at the smaller subdials until I get home.
