No. I'm sorry but no. You can't legitimately say that "anyone could tell this one would be the most popular". That's based entirely on your own opinion and I'll guarantee a random poll taken before launch wouldn't have returned a 100% result for that model as it's an utterly subjective view. The window you've been given isn't random, it was set at the point of ordering and frankly if you weren't happy with that you shouldn't have ordered.
And ENOUGH with this utter nonsense about custom bands taking away from the mainstream watches. All that work would have been done by the design team after their work on the current Watch was finished and would have had minimal impact on production runs if any (wouldn't be at all surprised to find out that Apple have small scale productions for prototyping that'd be used for this sort of work).
Look, I understand being upset that you may not get your watch on launch day, I really do. It's frustrating as hell but Apple have been up front about this. If they'd changed the delivery date or missed the one you've been given you'd have all the right in the world to complain. Until then though... you're still talking about a grand total of a two week delay at worst which you were aware of at the time of placing the order.
