Completely agree, its the same watch, same internals, just a gold case.
I'll third that. It's one thing to be aspirational, which Apple products are, compared to other smart phones, laptops, desktops, tablets, but those that aspire to own a great watch are not likely (as in no way in hell) to have an Apple Watch on their list. They may spend more to buy a gold Apple Watch, but there is zero way it would be priced anywhere in 5 digit territory. People aspire to own fine Swiss timepieces because they were fine timepieces a hundred years ago and they'll be fine timepieces a hundred years from now.
Apple's Watch may be a curiosity in 10 years, let alone if it even still works. My Seiko automatic hasn't missed a beat in 9 years I've owned it, and it's been on my wrist almost every day, through ocean, lake, river (including rough whitewater rafting), cutting firewood, working on my car, showering, running, etc. The case and band are scratched, but sapphire looks brand new.
Apple isn't anywhere close to offering a watch that will last for more than a couple of years and it certainly won't take the abuse that many fine Swiss and Japanese timepieces will.
I have an impossibly hard time thinking Apple will even get close to $5k for the gold model, unless they're making it from REALLY thick 18 karat gold, as the band and electronics cannot be worth more than $500, so at $4500 (assuming a $5k retail for the gold version), you'd have 3.75 ounces worth of gold in the watch.
Then Gruber suggests 4 times that amount - there is no way, none, zip, zero that there is almost a pound of gold in the watch, even if you value the electronics at $1000 of the $20k price. And no one can suggest that something that is cranked out by the millions has some far out value beyond the weight of gold, knowing that the internals are effectively the same.
Ludicrous thinking and I'm guessing Apple is going to benefit from all this hype when they release the Watch with significantly lower price points.
