I have a new interest in vintage dress watches - Omega, Longines, Hamilton, Tissot - 1960's and early 1970's. I have been trying to educate myself by reading comments on the watchuseek (and other) website(s). I have also been studying Ebay. I am negatively impressed with the amazing number of replicas (actually fakes, because they are advertised as authentic) on Ebay. Even my untrained eye can recognize many. Today I stopped by five pawn shops (at least one quite reputable) to look at vintage watches. A few shops had only fakes. Two shops had authentic old watches (but scattered among fakes). The fakes on Ebay and at these shops all share some common characteristics without consideration for internals (movements, case signing, etc.). I shudder to name them because the manufaturers of the fakes may take corrective steps to improve their fakes.
The fakes that I recognized both on Ebay and at shops were watches that were advertised to be 40-50 years old; each one had not a single scratch or blemish; none looked as though it had ever been worn; yet each had a brand new replacement band (bands had not even been bent -once); the replacement bands appeared to be the same for all the watches - dark brown to black textured leather made by some company other than Omega, Longines, Hamilton, Tissot. I wanted to pull out my car key to test the crystals (I bet all were acrylic).
I am not surprised that fakes are common in the price range associated with Omegas and more expensive watches. I am shocked that fakes are so common among the Longines, Hamiltons and Tissot's of the world. I will need far more education before I purchase a vintage watch (and I my psyche sinks to know that scamming is rife).
