Since we're in the rep world I'm inclined to think that all 'Swiss' reps actually could be frankens or 100% Chinese. In fact, I think that even the collectors are never 100% shure and they simply pass on what the factory tells them. I've experienced at least 2 times that one of our most trusted collectors unpurposely sold me a low beat 7750 for a high beat because the factory had informed him wrong. So I would never buy a Swiss rep for the 'Swiss' movement, but only because it usually comes with sapphire and AR, instead of mineral glass without AR on the cheaper Asian version.
Movements of reps I'm planning to keep are either fully serviced by The Zigmeister or are swapped by a sealed and preoiled ETA or DG2813 from Cousins. That's the only way to guarantee a quality movement.
