I ordered the 42 mm space gray and I think what probably screwed me into the 4-6 week range is that I took an extra couple of minutes entering 3 Apple Store gift cards. I think my order went in at 2:06 CST or something like that on pre-order night.
Yesterday I called Apple support to change the cc I had used to pay the remainder of the balance on my order, and the support person was really chatty with me for some reason. Wanted to know what I was most excited about as far as the new watch and kept reassuring me that my order went in soon enough that I should get it a lot sooner than 4-6 weeks. I'll believe it when I see it, but it was encouraging. (Not sure how the common phone jockey could even know that for sure.)
That being said, I can wait for the watch. I was never promised the 24th. Also, I already got one really awesome Watch-related thing via FedEx--my iPhone 6. Anyone who ordered an Apple Watch already has the item that makes the watch.......tick (pun intended), and that item is way cooler than the Watch in my opinion. So I'm going to just keep loving my iPhone 6 to death until my Watch comes.
