In the somewhat-related space of fitness trackers, there are alternatives to watches: keyfobs, ankle bracelets, rings. You get heart rate, sleep tracking, alarm clocks; I don't know if any do notification buzzes as well. I think companies will continue to explore this space because there's potential to find a big winner. But they're contending with the difficulty of miniaturisation on top of the challenge of usability. p.s. an idea that just crossed my mind was a smartwatch in a pen. Sure, pens are too easy to lose, but it could do some interesting things with input.
