Ditto Ezio.
Before clicking BUY, YOU, the buyer, should educate yourself on what the gen looks/feels like. Research gens via google or gen websites & go to an authorized dealer (AD) & try the watch on. Work the functions & see how it feels on your wrist. That is the best way to improve your chances of satisfaction when you receive your watch.
Otherwise, the QC pics look fine. But be aware that rep watches are generally powered by used/unserviced movements, so, if this is a watch you plan to rely on or keep for the long haul, have a local professional watchmaker do a full service. That way, you can catch/correct any problems & insure that it will be reliable for the next several years (until the next service - 5-7 years).
