Level of quality varies la, from really kurap to really ho liao. U could start by looking at what are called nwbig (not worth buying it genuine). This is to some extent a function of the gen manufacturer's level of quality and finishing - which is why u will see a lot of Panerai in this segment.
I don't really wanna go into too much detail on this for fear of derailing the thread, and risk being misconstrued as promoting reps la. But for what its worth, with the outward quality of reps becoming scarily better and better, I honestly feel that any serious WIS worth his salt who is interested in the commonly known watch brands on the market needs to arm themselves with knowledge of these reps, if only so they don't get ripped off.
