Amazing. Thanks for the inputs. Yeah i'm already aware of IWC portuguese problems and people joking about it blowing up a month after a purchase. But also have seen people having it fine, so not sure if it's hit and miss thing or version-specific problem, still gotta look into it more.
Definitely putting PAM 318 on top of the list though, read about the "mistake" before and gen pam forum was ranting about it, but tbh i don't care too much about that much detail, as long as it looks amazing, works well, and lasts long time.
Funny thing off topic though, is that a guy sitting in front of me on a train is wearing black sub as we speak, but don't have enough knowledge to identify whether it's gen or rep
