I bought a real Omega about 6 years ago in the states at a reputable dealer with warranty blah blah blah.
About 2 years ago I bought a copy of an IWC in Vietnam. At first glance the fake might pass with some, but if you know even just a little bit about watches or have the real version of the copy, you can spot this fake a mile away. It cost about 40USD after negotiating and it is a nice looking watch, but the feel and especially the finish is rough. I can barely wear it for a full day, where as the Omega i can comfortably wear day after day. My suggestion; forget about the fake and get a real brand that you can afford. I have 2 Hamilton watches as well and the are relatively inexpensive and FAAAAR superior to any copy of a Rolex, Omega ect. I am very partial to Hamilton because of the history behind the brand, they are Swiss made (they are owned by the swatch group, same company that owns omega) and they are damn nice watches for the price. Just my .02
I am a bit of a watch nut so if anyone has any questions about watches, please shoot me a message and I will try to answer it for you.
