Were all getting carried away.
Yes, I meant the SS edition - I dont expect the Gold watch to be $600. Thats probably $999 or higher

But SOLID refers to the case. The case will be Solid. Not Plated with gold, with a Stainless steel center. But I would imagine they will still not use much gold (not like Rolex quantities) as even though apple buyers tend to be wealthy, they've never outed a 'Lamborgini' model with real leather and whatnot for 10K. They're reasonable... to a sense. I would peg that at around the cost of a high end 5K desktop model, probably $2-3K fully loaded..
Now how much gold is that? probably around a 1mm thick wall *42mm*42mm.
So based on that, I get a GOLD value of about $400.
