Great looking watch you got here. Must say that the Hublot Big Bang V6 are very close to gen. I've got two V6 (stainless steel and rose gold, check my signature for pictures )
Buy yourself a H screwdriver and screw the bezel off the watch and put for example the V1 bezel or a genuine back on it. Further those details are typical rep flaws, these little things aren't bothering me but if it bothers you, you'll might be better off with a genuine Hublot. But you should question yourself, are these little things worth all that money?
