Calling all AP experts...

[Des23]

Hi all experts on AP, have a couple of questions here. Hope u guys can help me with ur inputs. Does the new black ceramic Diver comes in "I" series? Or it's has some "H" series as well? And from my understanding, the diver shd come with a "see-thru" back case, showcasing its wonderful 3120 movements. Does it come with solid back case at all? I saw someone wearing a H series with solid backcase, that's why I'm asking all these. Thanks for ur forthforcoming inputs...
