Respo,
If you are interested in a black Panerai watch, I would highly recommend a Pam 292 Radiomir.
It's my favorite size for a Radiomir(47mm's tend to poke your wrist), it has the classic, clean design of a Panerai, and you can even wear it with suits(it's sporty and elegant at the same time)
On top of that, it's a relative bargain.
Regards,
