I was noting the already established variants... which yes, are also derivatives of AP. I was simply noting that they are the established derivatives, and that there's room for more, but that Piaget has not really done anything here except make another variant, which is necessary commercially, but does not seem to have any other reason to exist. But hey, this is business. I would be the first to do the same thing! However, in collecting, we are attracted to what seems to transcend commercial necessity, and I was merely pointing that out, perhaps unsuccessfully.
