BBF has published the replica of Patek Philippe Nautilus 5711 for some time, I introduced their replica Nautilus 5711 before, they got the super clone 324 movement and made some improvements, for example, the dial color is closer to that of the genuine, the engravings on the movement plates are deeper. 3K Factory has not yet taken any action regarding these, this factory has been remarkably low-key in recent years, after all they have earned a lot because having kept the exclusive usage of 324 movement for many years. Just days ago, BBF made another improvement on the dial, I made a comparison between the old version and the new version, please check the pictures below.

The left one is the old version BBF published before, the right one is the new version BBF published days ago. The difference only lies in the dial. Please look at the letterings “PATEK PHILIPPE” and “GENEVE”. On the old version, the “PATEK PHILIPPE” and “GENEVE” are placed on two separate grids, while on the new version, the logo is trapezoidal, the two characters are centered in the groove between the grids. The pictures say everything. The font also looks slightly bigger.

The second difference is the grids, which become slight narrower on the new version. Please check the date window. On the old version, the bottom edge of the grid is parallel to the bottom edge of the date window.

On the new version, the bottom edge of the date window extends slightly beyond the bottom edge of the grid.

These differences are not flaws, actually genuine watches also have had these differences on different versions.

This Nautilus 5711 is a very hot replica watch, many customers bought it from 3K before and made some modifications by replacing its dial and date wheel, now I think the one made by BBF is very good enough, but the case still has one place that can be improved. The “eagle’s beak” feature at the end of the lugs is not pronounced. Many people care about this feature, before OME factory made this part very well, but they disappeared, it is said that they could not get the movement and produce this watch. Too bad. I made a comparison on the 5711 between OME and PPF, please check at https://www.susanreviews.com/2025/04/28/nautilus-5712-ome-vs-ppf/, you can better see the lugs’ difference here.

There are two approaches to deal with this defect on the case of the BBF, first, some watch masters in the market can polish this place very well, they do not charge too much. Second, you can pay extra to buy a CNC case and replace, but this case is very expensive.
