I had a dream that Tim Cook on september would introduce the "best watch ever created" 2.0 AW on stage and he'd announce they'd sell a band-less version.
Anyway I don't have the AW with me yet since it's still shipping but I got this one:
MoKo Milanese Loop Stainless Steel
And this other one also has some good reviews:
JETech 42mm Milanese Loop
I looked at videos on youtube for both and they seem to be overall worthy knock-offs. The first one specifically got a couple comments on durability where the video uploader would post an update comment saying it's still going strong (the color/magnet) after a few months.
I reckon the first one is space gray, not black, but it's close? Or perhaps useless for your taste.
In general I'd stay away from products with lots of 5-star "Disclosure: I got this item at a low price or for free in exchange of my unbiased and honest review" = sell out, you're lying.
Since we're likely 6 months away from the AW2, you want one, and don't wanna spend premium money, then maybe stay on the $20ish mark since that seems to be the usual. $40+ seems too steep and closer to say the knock-off link bracelet price.
