Over eight-and-a-half years ago, Ben noted prices of a solid yellow gold IWC being between $2,000 and $4,000, while something from AP or Vacheron would probably start in the $4,000 - $6,000 range. In 2021 we sold two yellow
link gold IWC caliber 89s (here and here) for around $3,500, two yellow gold APs (here and here) for just under $5,000, and a claw-lugged Vacheron for $5,900.
