Hey! Amused to find this thread, I've been waiting too... Did have one email exchange with Chloe at Nomad, who did her best to be soothing and said they'd been surprised to find out how limited the carrier's tracking infrastructure was.
The tracking link mentioned PostNord, so I did a little digging and got to
http://www.posten.se/en/Pages/Track-and-trace.aspx which provides additional information. I synthesized the following tracking information from both that and the DirectLinkPlus site - and from the USPS site - your tracking number works there too:
June 1 - (Hong Kong?) - pre-advice received
June 4 - PostNord Receiving HUB (in Hong Kong?) - received for processing
June 18 - MALMO UTR/MMAH,Sverige - departed Direct Link's international terminal towards U.S.
June 19 - Chicago - Processed Through Sort Facility ISC CHICAGO
The entry on the 18th had me confused for a bit, but (Wikipedia to the rescue) "Sverige" is Swedish for "Sweden", and Malmö is a (coastal port) city in Sweden (right across from Copenhagen, Denmark). And, PostNord, the carrier in use here, was created by a merger of the postal services of Sweden and Denmark, so it's making sense...
Given the locations and times, it's pretty clear that our watch stands (or mine, at least) have been sent from Hong Kong to the U.S. by putting them on a ship (a guess, given the two weeks involved), sailing them from Hong Kong to Sweden, then putting them onto a plane and flying them to the U.S. (landing in Chicago) where they are now going through customs, and will soon make it into the hands of the USPS for the last leg. So they are making progress, and the end is in sight.
Once a package reaches one of the USPS's ISCs (International Sorting Center? basically "customs"), it can take anywhere from a few hours to a few days for the package to clear and reach the adjacent post office (in my experience), and then it'll take however long it takes the post office to deliver you a package from Chicago.
And once a package that will ultimately arrive via the postal service gets into the USPS system, stateside, that same international tracking number you have will work on the USPS site for delivery tracking (in my case, I rarely look at the sites directly - I use JuneCloud's "Deliveries" app on iOS).
But who thought that taking a cruise to Sweden was the best way to get from Hong Kong to the U.S.? Rather than say, just crossing the Pacific Ocean? Nomad went out of their way in their (last?) update, to say that they'd chosen the carrier that would get them into our hands the fastest. Meanwhile, in the past few months, I've purchased a few items from Hong Kong on eBay (watch straps for an analog watch, not that it matters), which were all delivered in 5 to 7 days via normal postal mail.
If they'd said, "sorry, these will take a while to arrive because we thought they ought to be well traveled, and this way was cheaper for us", then fine. But they went out of their way to say, effectively, "this will be the quickest way". SMH.
BTW, for anyone keeping score, mine is order # USA12810, for one Space Gray stand, placed April 15th, with tracking number RE204870285SE. Best Buy's site informs me that 20 stores within a two hour drive (several are only ten minutes away) have the stand in stock, and the slightly-higher-but-no-shipping price would work out to a total of six or seven dollars more than I paid direct to Nomad. And I would have the opportunity to examine it before buying, rather than paying and then getting a mid-course design change that makes the elegant stand somewhat less elegant. Not feeling too kindly towards Nomad at this point.
Oh, and my Apple Watch? (42mm SGS) Apple's initial extimate was "Available to ship: June", and their final estimate was "Should arrive June 4th-8th". It shipped at the end of May, took I think 3 days from factory to doorstep, and was meticiously updated every step along the way by FedEx. And it arrived June 1st, ahead of schedule.
