Best Of

I have had a Garmin Vivoactive 3, Marie also has one and it is a really great fitness watch, easy to use app, automatically synchs with Strava. It has many features and is very well loved and usable with GPS for mapping runs/etc. Just recently upgraded to a Fenix 5S and its also great, would recommend this watch as well, has all the usability of the Vivoactive 3 kicked up a notch.

Wow, I didn't even know there were ever smart watches with e-paper. Sounds doap!
I'm a Garmin user but because my primary use is the fitness stuff, so not helpful for you perhaps :-D It does get through close to a week without charging, depending on how much I use the GPS. Faces are pretty customizable with most brands now as far as I have seen. Vibrating alarm is also standard now (mine doesn't have the ability to make any sounds at all). I think most are fitness focused apart from maybe the apple and android watches which are more smart-phone feature focused. My Garmin Vivoactive has a touch screen and phone notifications too, but fewer of the smart-phone sync features. Touch screen vs no button based might be a dividing factor for you.
