*You're*
Now that that's taken care of. No I'm not serious.
But I seriously think that Apple will sell a decent amount of bands regardless of their price range. If you've previously worn high end stainless steel watches like Omega, Breitling, Rolex then a link band at $450 with the awesome functionality that the link band has is not overly pricey. Somehow I don't see Apple changing the "adapter"-connectors for the second generation so it won't be a waste of money.
But for "normal" people who don't normally lash out several hundreds of dollars for bands I can see third party straps being a more attractive alternative.
I would have zero problem putting a $450 band (or more) on a classic, almost art of watches that you are talking about.
I wouldn't even have the problem doing it for Apple Watch Edition. But how many people do you know that put one of the high end Omega, Rolex, etc bands on a Fossil Watch? Or even a $100 Seiko that was bought off Amazon? That is what we are talking about here.
All the Apple Watch bands are overpriced. I'm still kicking myself for buying a LL. There is nothing special about any of them except perhaps the ML and the Link. But IMO, it makes zero sense to put a $450 Apple band (no matter how great of a band it is) on their a $400 watch. And no, it really doesn't make any more sense on a $550 watch. Your example the watches cost $1,000's or even 10's of thousands.
Especially since there are as good of looking link bands by well know band makers in the $100-$150. Not to mention the bands from companies you mention that are fantastic.
While technically any non-Apple band is a 3rd party band, there is a significant difference between the cheap Chinese knockoff's and even Kickstarter band v. The well know, established bands. Heck to be honest, I'd consider paying the $450 link band for my SG sport if it were made by Tag. But never for the Apple.
Now, to be fair, this is just the first wave of bands even by Apple. They very well my come out with more. In fact, I'd argue they have too. Especially for the SG and SS black since they currently offer few choices for them.
