Panerai is supposed to have made only 500 hundred of these watches with the PVD movement, the later modela come with a smoked glass ace back to give the look of PVD but without the expense.
It is really a lovely watch that catches the regard.
It definitely has a presence on one's wrist.
I am not in a position to say whether it will be the biggest Panerai collectible.
I figure that it will hold ifs value.
Best regards,
