Snap! Space Grey Sport ordered via the Apple Store app. Website still down. Date range for delivery is 24/04/15 to 08/05/15. Hoping that's just deliberately vague.
Mine came up in the app right at 3:01 AM EST. Selected my prechosen watch and checked out in a matter of seconds with apple pay.
My only concern/question is whether they are doing in-store pickup at 8am like they did with iPhones? I had planned on in store pickup but did not receive the option.
Holy hell that Space Grey 42 mm Sport slipped to 4-6 weeks shipping quickly. I'm not being remotely sarcastic when I say that I'm glad I checked out with Pay for this one.
