From a while Panerai is realising quite boring pieces, I mean existing references where they change only dial and strap and call them limited edition or whatever. Best.
Green with copper looks better IMO, although copper is a ridiculous material to use on a wrist watch. So maybe yellow or rose gold with a green dial? ...
that must be cleaned and maintained. Apart from that, it's very soft and gets nicked too easily. I can't remember any of the high end watch manufacturer that produces silver cases
