The Panerai luminor replica watch has become more and more popular, and more and more in the fake world, get a lot of attention, certainly a lot more than it did, let’s say, about five years ago. I can even safely say that, aside from , Panerai is one of the most replicated brands out there, both as an homage (where small details are changed and produced under a different name, Parnis, for example) and as a Panerai replica. Whichever it is, the end product is satisfactory to say the least.
