Found this one in my Amazon wishlist, I think I saved it when I saw someone mod it to fit the ZW3... Seems pretty nice, probably not light if their claim of solid links (rather than stamped) is true but still, it's got sort of a unique simplistic design that I think goes well w/the ZW3

For $29 I might try it once SteelConnect's adapter ships out. I like that it's made for QRs too, and I've never worn one with that kinda hidden clasp before. It was actually $40 thru much of last year according to Camelcamel.
My only worry would be the color matching/clashing, specially if SteelConnect doesn't nail theirs... One color transition from watch to adapter wouldn't be bad, but two from watch to adapter to band might look odd (and the ZW3's lugs already stand out as it is).
Edit: Damn Amazon's combined listings, had to edit the link 3x until it pointed at the right one.
