Nice.
I have two Carrera's. One with Gen movement, all gen hands, rotor, crown, bracelet etc and one that is similar to yours with silver screws and gen datewheel (gen rotor on its way soon).
I don't think it is a huge amount thinner than the rep. It is a bit, but I think the brighter red is a bigger difference. The rep hands are too dark.
The gen hands make a massive difference too all round. The swiss ETA movement also make the hand stack look taller.
They are very nice though and yours looks amazing on that strap.
I will try and get some pics up of mine soon.
