Thanks for all the great answers. So Joshwatch is the place to look if you want to be sure? There are two things that seem to be hard to get on this watch: The Omega logo. The original letters are in black (not silver) and doesn't have the letters "melted together" or "underlined": O_M_E_G_A, O-M-E-G-A. The other thing is that the dial should be in silver, not white.
Can you always be sure that the second-hand/pointer will move variable/smooth and NOT jerky/stop-go/tick-tack on Joshwatch (I apologize for my bad english)?
Guess this is a common and annoying question: Is there any thread here where you can see more trustable Omega-replica-sites?
Original one:
Thank you all!
