This sold as KM90 is like a flattened and even more compact non-curved U17.
With a 35.5×30.8mm display in a 39.5×34.0mm body it offers really thin bezels and hence an amazing 81% display coverage, and even better than that if you look at coverage under the glass.
The 6.9mm outside the protrusion makes it one of the thin ones too!
It uses the H-band app just like the U17, and that is not the worst out there. It is the same screen-size and chip as the U17 too, though the 180mAh battery is 22% less than the U17.

And uses standard 20mm bands.
It has the same clever band attachments as the U17 it seems, allowing it to go anywhere from straight out for large wrists to straight down for tiny wrists.
I ordered it and am awaiting its arrival and will update this.
