I dunno if he'll get $4K for it, but that's a great watch. If I remember correctly, this watch was posted on 'Risti.com a while ago. It started out as a real RXW MM20, and the fella had the dial/hands made to fit the Rolex movement.
From a purely aesthetic standpoint, I think the watch looks like crap from the front. The dial and hands both look a bit too raw/homemade/rough to me. Plus I'm not a fan of gold hands.
He'll probably get that price, though. It's certainly unique, but I'd rather have one of Enzo's Angelus powered 6152s that he's built. No homemade dials/hands there....
