Round smartwatches make no sense and I don't know why anybody is making them. Scrolling content needs a constant-width display. If there was a square android watch I would get it.
Clock face, compass, activity tracking, heartrate measurements. For most of those, square vs. round is largely irrelevant from a functional perspective, but round feels more aesthetically pleasing (to me).

You can fit less information on it, even with the same number of pixels. There is nothing you can do on a round LCD that you can't do on a square. If you find it aesthetically pleasing, great. I like round as well. But for people who like round, and use round to display a clock face, try a mechanical watch. They are awesome. ]
