The problem with some of these gold watches now is that the gold value has overtaken the collectability value. I admit I’m far from a C-case expert but if we assume the gold value is €5.5-6k, I still think the ‘collectability value’ is €4-6k so you’re potentially in the horrible position where many collectors are potentially being priced out by gold buyers. Just because the intrinsic value is now two grand higher, it doesn’t mean a collector is suddenly willing to pay that.
Again, these are only my thoughts, but I think in a private sale, you’d struggle to get above gold value if it weighs out at €6k
