My wallet regrets ever discovering this hobby! I came learning how not to get fooled as I was buying a gen from an AD - yes, I'm paranoid!!! I bought it but the thought of buying an "identical" piece, at least from the outside, consumed me.
In the end, as others have said, "you know" not others. Although people may notice your watch, the will have no idea. And to be honest, unless its a real shitty rep, at a glance, it's tough to be called out. You have to remember that we spend our days looking at super macro shots an hi-res screens, zoom in, zoom out, open a different window and compare. At the office, at the park, wherever, how often will you say, "Nice watc, do you mind if I take a look at it?"
This never happened to me. You comment but never handle the watch. If I'm not happy with a flaw, I fix the flaw change the watch.
Enjoy it for yourself! There is no greater pleasure than being in the car, on the beach, anywhere for that matter and glancing at your wrist wearing a piece you truly love. Once you spot a flaw, you won't be smiling and the person next to you won't know the difference.
