I have to agree with Scoobs on the matter whether a replica should 'fool' a trained eye or not.
As far as my opinion goes, I like the way an SMP looks but don't want to pay 1,700 euros for one. So reps are my opportunity to own watches that have the looks I love without doing 'favours for sailors' in the docks or selling coke to highschool kids. Of course, the closer a rep comes to the real thing, the better, but I'm not paying half the price of a gen SMP for a rep, parts and shipping to get a watch that looks 99% like the real thing. That's why I've accepted my flawed dial, He Valve, crown guards, bracelet screws and so forth.
IMHO, the only way to get a watch that can fool any watch connoisseur is to buy the genuine SMP, other way, someone will always find it out. And once more, for me, owning a great looking automatic watch is about taste, not about money, and I believe that a closely repped Omega SMP is as tasteful as a genuine.
That said, I do have respect and understanding for the guys who do want to push the boundaries of reps, for they put some hard and smart work into a cool hobby.
Cheers!
