That's what I thought until I started carrying a wrist watch a few years back. Now I wont go anywhere without it.
Checking the time, as stupid as it may sound, is way easier and comfortable to do than pulling your phone out.
Setting a timer for the boiling water on the stove way quicker and easier than pulling your phone out.
Going for a run and wanting to time your runs, I don't even carry my bulky ass phone on my runs, way easier to do on a watch.
Sitting in the sauna after the gym and want to keep track of time, wrist watch. Etc, etc, etc.
