I use the Modular watchface, and put things like other timezones on it, and a quick one-tap to timer. (great for cooking, or medicines, or Pomodoro, etc)
If you're a MacOS user, you can auto-unlock your computer with it (sounds scary even typing it, but it's damned handy)
A quick swipe up and you can use it to "ping" your iPhone (phone makes loud sonar sound) in case you can't remember where you put it.
If I'm on other side of house, and phone rings, I can actually answer call with watch and talk Dick Tracy style :-) (people tell me it sounds pretty clear)
