Well, AliExpress saw a huge wave of postings claiming to sell the "Apple Watch Link Band" as a 1:1 clone lately. Somehow most of them have been removed or changed from approximately 30 USD to 60 USD (all pretty shady) during the last days. There are several shops run by the same person(s) - one e.g. using the name "Oatmall" and another called "Oaec Electronic Company" - claiming to have that 1:1 clone. When I spoke to them however they said it would not be a real 1:1 clone and send me pictures of the actual band they claimed to be shipping. I uploaded the photos with a link to the article
here. Besides the lugs that band pretty much looks like the JUUK link band.
Then there was that posting on Taobao which exactly looks like the band from JUUK (including the lugs). Someone on the forum posted a link and even tried to order one to the US. I can't exactly remember where he posted it though. No matter what, I think you don't need to spend the effort to buy on Taobao right now since what turns up there usually also turns up on AliExpress a little later. They probably are about to ramp-up production on that thing - that's usually the case when those first photos pop up here and there.
