Nautilus is always popular in our market, I recommend two factories when you are going to buy a super clone Nautilus 5711, they are PPF and 3KF. Absolutely you can directly choose a 3K Nautilus 5711 and do some customized works to get a perfect watch. For example, I got this Patek Nautilus 5711 from 3K factory and replaced its dial with a green dial from SW factory, now its green color is closer to that of genuine watch.
