There are a few variations that I am aware of, with or without the correct caseback. However one thing is clear, only the latest version is worth buying.
This one has no decent AR, bad datemag/font, bad bezel tachometer and numeral engraving (too bold), inner bezel numerals too small, wrong dial colour and font, plus there should only be three red squares between hours markers 11-12 and 12-1, not four....
I would guess the rubber strap does not smell of vanilla either
So all in all a very poor replica, even more so when you compare it to the latest Chopard, which is, in my opinion, one of the best replicas ever made.
hooky I really hope you can return this watch, it is not in the same league as the new version..
Cheers!
