Just like NewApplyBoy, I, too, am glad I found this thread- only maybe the 3rd time I've come into the "Accessories" subset of the Watch forums here, and this was exactly the stuff I was looking for!
I have a silver aluminum AW Sport w/Blue Sport Band (had it the past 3 and a half weeks) and just today my Black Sport Band was delivered by UPS. AND just yesterday I made a trip to one of the nearby Apple Stores and picked myself up a Classic Buckle- and I love them all! (And- as a side note, my trip to the Apple Store yesterday was actually my first time seeing any other Apple Watch or band in person. I never scheduled a try-on appointment or anything of the sort prior to preordering/receiving my Watch. So was a pretty amazing trip for me- first time seeing the Stainless Steel Watch [and gold Edition obviously for the matter], and more importantly to me and this thread, my personal opinion on a number of the bands was changed- some VERY drastically. I went from hating the Milanese Loop to almost considering ordering one, and while I only 'disliked' the Leather Loop, that one also grew on me to the point I was considering it as well. Steering back from my huge tangent- the Classic Buckle was the only band other than Sport's Bands I had considered prior to going into the store [love the Link, but not for $450], and I left the store very satisfied with one of em, which may well become my "primary" band. BUT, all of a sudden, I was very interested in every band option offered in one color or another).
Back to square one- So the Classic Buckle came with it's own 'personal case' in a sense- just pretty much a miniature version of the white plastic elongated case the Apple Watch Sport's come in, so I figured I could store it in there when not in use, but I ran into the issue with where I would want to keep my Blue Sports band. Then today, receiving the Black SB from UPS, it didn't come in any real case that it could be stored in. Which all prompted me to begin looking into storage options.
Anyways, I have nothing to offer up myself yet, save for the above short story, long, but appreciate people sharing what they've come across!
Cheers!
