I can check my watch without having to pull my phone out my pocket, depending on what you are doing that can make a huge difference.

Practicality and functionality mean different things to do different people.

I have to say, last time I had a phone break, the first thing I dug out was my watch. You really notice a distinct lack of visible clocks these days when your phone dies and you don't have a watch and people these days seem to look at you like there's something wrong with you if you ask them the time.

Being able to start and stop a chronograph/stopwatch to time events without having to look at it whatsoever can be life-saving at best, amusing at worst. Even a watch with a simple minute-gradiated bezel is so much better than relying on my memory to remember a start time.
