Bud, if you buy the Soprod Pam in the sales section, it has a "gen" soprod movement. The same movement as the real deal. There is zero difference and will last every bit as long, its a panerai outsourced movement. I sold my gen panerai, and have nothing but Soprod PAMs. Same movement.... If your really looking to sell your gen that is the absolute way to go. Forget the Noob, H stuff. Yes they are awesome. But if your selling a gen, buy the Soprod.
