C Factory, also called CF Factory or CF by many people, is actually Clean Factory in this field, what about C+ Factory, it is not the same factory, it is also not a branch of Clean Factory, I do not know the background of C+, maybe being operated by a small team in the market just to make some quick money, C+ has existed in this area for about two years, about its reputation, it is just so so. My overall suggestion is just buy Rolex from Clean(C), they make better quality Rolex than C+.
I admit that C+ Factory makes good quality Submariner and GMT-Master, but their finish is not as good as Clean, the case finish is not as good as that of Rolex from Clean, some people have complained its fat lugs, but in C+ promotion, they said their case and bracelet use the same finish as that of previous AR Factory, I doubt this. 116610LV is still hot, C+ also makes this replica and they claim their 116610LV is the best in the market, I do not think so, the best 116610LV is still from Clean.
About the GMT-Master II Pepsi and Batman from C+ Factory, they used VR3186 or VR3285, actually these two movements have no difference in function and power reserve, about 1 or 2 days, but I am not sure which Chinese movement factory makes the 3186 and 3285 they used in the GMT-Master II, the movement quality is ok and these two movements have been widely used. Just weeks ago, Clean Factory announced that they will use Dandong 3285 movement in their GMT-Master II, this is a good news for us because Dandong 3285 is said to have 3-day power reserve, but currently it is still very hard to get one GMT-Master II with this movement from Clean, you need to wait for a long time.
So, about Rolex from C+F, they are good quality but still can not be compared with Clean. For 40mm Submariner, Clean has advantage in their green ceramic bezel. For 41mm Submariner, I suggest VS versions with Dandong 3235 and I hope Clean will also use Dandong 3235 in future, so their 41mm Sub will become better. For GMT-Master II, the finish of Clean is better than C+, the movement is Dandong 3285, which is more advanced and better than VR3285 from C+.
