There are different grades of fakes, some look darn good. I bought a knock off Panerai Luminor in China last year for about $100US. The thing looked amazing. I wore it to work and a Doc I worked with who is a watch aficionado notices it and says "you spent $7,500 on a watch?". To which I asked "was that too much?"
Anyhow, he was dying to have it and gave me $100 for it. Better part of 2 years later he still wears it from time to time and it still works fine. He often boasts about how many people he's fooled with it.
Milgauss is a great looking watch. If you aren't bothered wearing a fake, go for it. Just understand that it's a crapshoot as to how long it will work and how well it will keep time.
