VS factory has released many Datejust II models, and besides this black one, other colors like blue, silver and grey are also popular. Clean also makes this black one and both factories make Datejust in real 904L stainless steel, but VS uses the better 3235 movements with longer power reserve. More people are choosing the Datejust 2 from VS. It’s no surprise that all of the watches from Rolex are in the top five best sellers list.  
The replica AP Royal Oak 15400 has been a popular watch in our market, and I recommend two factories, ZF and APS, both of which do the best job. But after the release of the V3 version from the APS factory, I suggest you get it from the APS factory now. Its clone 3120 movement is much closer to the real AP 3120 movement and is the most authentic super clone internal 3120 movement we have on the market.
The PP Factory, also known to us as PPF, has the best selling replica Patek Philippe watches with its Nautilus 5711 replica. In my opinion, both Factory 3K and PP make the best Nautilus 5711 replicas, PPF was the first factory to make this blue dial in the correct color, closest to the authentic watch, and now that it has been updated to V4, I recommend PPF first, considering the Nautilus 5711 is usually out of stock at Factory 3K.
Another Rolex, and yes, I wouldn’t be surprised if they are both Rolex watches on this list. This 42mm replica YachtMaster has become very popular in the last two years and the best ones are made by the VS factory. JVS and GM factory also make these watches, but VS makes the best clone 3235 movement. However, if you order from VS, you can’t get the watch immediately, you need to wait a few days, JVS and GM usually have it in stock.
I learned its name, Batgirl, from a reader and it is the GMT-Master model with a black/blue ceramic bezel and Jubilee bracelet. Several factories are producing this replica GMT-Master; besides Clean, V9 and GM are the other two factories I recommend, but Clean produces the best, and if you consider the high price of Clean, the V9 and GM versions are also good. I still wish Clean would correct this even though people won’t open the case back.
