In the past, I always thought that PPF makes the best replicas of Nautilus, actually I was wrong, my opinion changed, especially after reading some stories about 3K factory. The movement equipped in Nautilus 5711 developed by 3K factory is the best in this field, and the case shape and size on 3K Nautilus are closest to that of genuine watch. If you still think the blue dial version of Nautilus made by PPF is the best, but be sure to choose from 3K factory if you want the best Nautilus replica with other dial colors such as this white.
