Btw I looked more closely. The trick to getting it to latch is that the long band must go over the short band and each of the magnets must snap in with the one below (I.e. it’s not infinitely adjustable but still highly adjustable).
Done the other way around you end up with a loose fit. It’s natural to want to do it the other way.
EDIT: also meant to add that it would seem like the FineWoven on the watch band is an entirely different material than on the phone cases. On the phone cases it’s almost like a faux-suede but on the watch it’s more like a super fine mesh material. I don’t know what this means for long term durability but given the issues with the cases it might not be the worst thing. I will say the FineWoven on the watch band is super appealing and very comfortable, surprisingly moreso than my previous braided solo loop.
