I think this watch is a super well made replica. Every single detail is very nicely done and the watch looks stunning on your hand. The fit is perfect and every button works like its supposed to. The movement….. well its NOT Swiss made as seller says. Its an Asian Clone of a ETA Valjoux 7750 – BUT its a very good movement. Mine keeps time within the Swiss specifications – that 2-3 sec a day and I can live with that. But you pay 300 $ to much witch is not ok I think.
