Mark my words. The Edition won't be selling well. Apple might spin it as a "wow, it's sold out always," but that'll be because they're making hardly any of them.
But let's get to the bottom of what's really going on here. Why is it so hard for the Apple faithful to say "Hey, I really like this watch, but the gold one at 10x + the price is stupid." I haven't heard a single good rationalization for why Edition exists, or why it'll be popular. Not one. If I hear one, I might be inclined to change my position on this, but nobody has rationalized it yet.
Burberry sells 18kt gold watches for $15,000 with leather bands. They also sell similar gold-plated watches for $3,000 and stainless steel watches for around $500-$1,000. I'm sure Angela Ahrendts knows the mix, and could have guided Apple as to how many they might realistically sell relative to the other models.
Also, given that the dedicated Apple Watch stores are outside the US, we need to consider the possibility that foreign markets will be more important. London, Paris, and Tokyo (particularly London) have lots of very wealthy people, including lots of foreign money.
