how would it be "smart" without some kind of way to get data from your phone (or other wireless data source)? are you imagining a wired tether and periodic sync, like Palm Pilots?
I guess technically I mean more of a fitness tracker watch. Having connectivity to my phone isn't important because I can't take my phone into the places I can't take my current smart watch. I have a Garmin Vivoactive 5 that I used to wear, but having to take it off before going to certain meetings got to be such a hassle that I just got myself a Casio 593 to just not have to worry about it.
A nice bedside dock in which I could mount the watch and have it sync data at that point would round the whole thing out.
