All true, but aren't you losing sight that these are only reps? I mean most people wouldn't know a good cannon pin from a bad one, let alone what a Panerai is. I look at them as reps ALWAYS. If I wanted perfect I would buy the genuine. For $200-$300 you get a real good copy, I can't understand adding another $300-$400 in mods to a rep, it still won't be real, just a better copy.
No offense to modders who do this as a hobby, I think be able to successfully tinker with these things is an art. But let's try not to lose sight at what these watches are.
