I did have a regular watch back in highschool, and all it gave was the time and date. Now that I can look at my phone or my computer screen, it would be of little benefit.
My smartwatch comes with a step counter, which gives a little goal for every day. Plus it shows notifications from my phone. It makes it so much more comfortable that I don’t have to pull my phone out for every single notification. Just having a look at my watch, and I know if it’s important or not.
