This is what you are looking for, at least the only thing that actually looks like it will be released in the near future: I like it a lot. I've found that I would much rather wear my mechanical rolex than any smartwatch, but if I could have it integrated into the band then I'd be all for it. I'm quite surprised no one else is jumping on this, it takes the decision away which watch to wear.

I saw this earlier as well and thought it a great way to merge smart functionality and mechanical timepieces. I hadn't seen the one you replied to but just realized it's from Kairos, same designers of what I consider the best looking and most useful implementation (well, at least smart watch design since they still aren't available) so far. Between the two, I like the the Kairos T Band as having the display on the very bottom makes it very susceptible to scratches and dings, as I've experience wearing my Microsoft Band that way.
I am taking it all with a grain of salt however since as you've pointed out, while the designs looking very promising, Kairos still has given firm release dates.
