I ordered one 42mm SS Classic Buckle (my watch and the first one I ordered) at 3:03am and two 38mm SS Classic Buckles that I ordered later (confirmation at 3:28am and 5:31am).
Of course the two 32mm watches updated to "preparing for shipment" yesterday while I got to sit around stressing about my watch for the last 24 hours. But luckily after checking Apple's site all day and refreshing multiple times, my 42mm has finally updated to "preparing for shipment" as well!
Still have a June watch that I'm waiting on but at least it's not mine. Lol. Stay positive guys.
