Hi, Nico,
The JPM was (one of) the first piece from the Phillip Vaptzerof era, a true high point of audacity and design in the Royal Oak and Offshore timeline.
AP frequently did a sub-series "Friends and Family" within a larger limited edition.
Ironically the JPM elicited quite a few uncomplimentary initial reactions when it was released. ..
Cheers,
TM
