you have to remember that most quality reps will fool 98% of the people... well, I take that back. Everyone will assume you have a fake if you wear a Panerai, Rolex, or other high-end watch, no matter if it's gen or rep!
Just like any project, the final, fine details are the most time consuming and expensive parts of the project. I haven't been here long, but I can see that!
And "perfection" is relative. It's just like the difference between the restoration of a classic car; "restoration" may mean a new paint job and recovered seats to one guy, or a total nut-and-bold disassembly and rebuild to another. Big difference!
Like others said, probably the best way to get a really, really great rep is to learn about them first, then buy a nicely modded version that someone else did. You might even get a deal doing that!
