I looked at the listing. A few things right off the bat, he’s never going to get $17K for this. It doesn’t matter if it’s new or not. The watch is listed as ‘never turned on’, which means that battery is completely depleted and it will not turn on, especially being it’s almost 6 years old. Also, the fact that the integrity of the package has been opened, will also devalue the watch. The most I could see that seller making off the 18 karat gold Apple Watch is maybe $10K, if that. Realistically, he’d be lucky to even walk away with $8K, and that’s just what the casing is probably worth.
