I got complements on my 111, 183 and 212 more then few times. Few times random people said nice Panerai, few times just - wow, nice big watch.
No one has ever asked if it's real. Few people at my work that know of the brand never questioned it. Up until a day one of my cooworkers who's seen me wearing them for a while (111 for over a year now) and who is into watches and has few gens said: You spend some major coin on those Panerais. I could not stop myself and told him about 99% acurate reps and my 111-project, new crown guard, crown etc. I explained that I like Panerai designs but I choose not to spend close to $18,000 (including tax) on 3 watches. I let him inspect 212 I was wearing that day and he was pretty amazed how good it is. He actually had a gen watch with 7750 movt. on that day, we compared both see-through cases and he could not stop saying that he never thought there could be such great replicas on the market.
