The MKF Nautilus V6 has two problems if you plan on using it as a base for a hybrid. One problem is the stiff bracelet which does not wrap/curve nicely if you have a small wrist, there will be gaps on the sides. However, if your wrist are larger than 19.05 cm (7.5 in.) there is no problem, the bracelet will fit fine. The other problem is a misspelled word engraved on the movement. You will need a loupe to see this mistake and with the watch on your wrist nobody will ever see it. So if your wrist is larger than 19.05 cm and you can overlook the misspelled word, the MKF 5711 V6 is an excellent base for a hybrid PP 5711. This watch is on sale at Trusty Time for around $350.00, so the money you save can help pay for the PPF hands, dial and the required PF date wheel. The PPF date wheel is no longer available, but the PF date wheel will fit according to members who have done this before.
The best known rep PP 5711 white dial is from PPF. The PPF hands will be needed so that the lume will match. I suggest you ask if the watch, dial and hands are all available first before starting.
The required Keylog PF date wheel can be ordered by going to the top of the Patek Philippe sub forum and click on the sticky thread, Nautilus Date Wheel Project, go to page 1 and the click on the link provided. It cost $40.00 plus shipping. This part is required because the date wheel of the MKF Nautilus 5711 V6 will not appear properly on the PPF dial date window. It needs to be replaced.
I do not know of any guide or instructions on how to do this modification. Most members send their watches and parts to a modder. If you are in Germany, I recommend slaughterer62, you can contact him via PM and ask him about cost and other information.
I wish you success on your endeavor. All the best.
