I just got notice of the item shipping. I ordered the SS Classic Buckle 42mm Within. 20 seconds of going live on the Apple Store app. My card was charged yesterday, two hours later it changed to preparing or shipment, and now, about 24 hours later there is wind of it shipping. For me it's coming UPS next day air, so don't fret all you who are waiting. There is still time. With my iPhone 6 I actually didn't get notice until the day of that I would be getting it. When these things happen they happen real fast.
FwIW, I live in MO and its shipping out of Mout Juliet, TN. Interestingly, it says the shipping label was created on a date that works out to be this coming Thursday. Apparently Apple has a working time machine as well.
