Withings wins that particular narrow field handily, their watches do about four things: notify, tell time, track steps, and heart rate.

But they have real hands, and the 'smart' part is subtle enough that most people just see a watch, a couple weeks battery is realistic as well.

Pebble hit a sweet spot in terms of how much you can do with it, while being good looking with a hardy battery. If we limit the comparison to the last two of those things, Withings is in the lead, not to mention still actively sold and supported.
