That kickstarter is a nifty idea, I actually just bought this band : https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
It was fairly easy to modify to fit the zenwatch3, and the color is a perfect match for the gun metal zenwatch3. Pictures 1,5 and 6 are what you get (2,3,4 show a different lug attachment), and with a 1/16" drill bit and a dremel you can modify it to work. Just remove the lug that attaches the band to the watch (tool comes with the band), this leaves a narrow link exposed that will fit the zenwatch. Then use the drill bit (in a drill, not the dremel) to widen the hole so the 14mm pin from your zenwatch fits in that link. Tip here, use a drill, and on very very slow speed, and hold the link with your hand, that way if it catches you don't break the bit off inside the link.
Now the pin from your watch should fit in that link, but you'll notice the quick release stops the pin from being centered in the link. The last step is to make a small notch in the link to make room for the quick release knob on the pin, or if you can find a 14mm pin without a quick release you'd be done. i used a tiny cutting disc that came with my dremel, but i'm sure there are other ways, the notch only needs to be 2mm deep in order to fit. If anyone is interested I can post a picture of what it ended up looking like.
