Agreed. I would also add a silent vibrating alarm to the list. Though interestingly, non of these features need much of a display or interface.

I have a Mi Band 2 with a 1 month battery life. It does everything i Ned. I'm pretty sure all of the above features would be possible with the Mi Band display, at a very low price.

I think smartwatches will split inyo fashion (Apple) vs Utility, depending on whether Google or Microsoft figure oit payments and assistants.
