Just ask any of the trusted dealers here. You can check their reviews and choose one. Buy the modified Valjoux version they have and not the Quarz. You will be amazed if you get the watch. This is a very good rep. Even has a real ceramic bezel. It is very accurate and I think it looks more like the genuine then for instance the as super rep marked UPO Seamaster. I own them both by the way and however the Omega UPO is a nice watch the Tag wins it for me as out of the box rep. The reps even have unique serials.
