The renderings above were sent to us by Edgar Rios, and heĀ imagined what is probably best described as the evolution of Apple’s sixth-generation iPod nano watches. With Apple’s recent patent covering a slap wristband form factor, more concepts seem to be leaning toward a longer display that would take advantage of a flexible or curved display and not one that’s square (like the sixth-generation iPod nano) or circular like more traditional watch faces.

This next set of mock ups were done by designer Martin Hajek for the upcoming issue of MacUser magazine (via Gizmodo) and imagine more traditional materials for Apple’s much rumored watch product. Like the concept above, Martin’s appears to also imagine a scaled back version of iOS and is reminiscent of the sixth-generation iPod nanos.
