While the existing Patrimony Moon Phase Retrograde Date versions (those being in white or rose gold) retail for $40,100, each of the fifty platinum pieces being added to the Collection Excellence Platine will sell via VC boutiques for $67,000. With platinum forming everything from the case to the dial, and even the thread used for the strap, you kinda knew it was going to cost a pretty penny. That said, you get a very limited and lovely watch in return.
