I love my BP v1 5711. The only negatives for me were the green tinge to the dial and the noisy rotor on the miyota movement. I saw a thread where someone oiled the rotor on their AP 15400 royal oak, which also uses a miyota movement and this inspired me to try the same.
Here's what I did with mine that made it as quiet as my eta and 21j based movements.
1. Order some oil online. I am not an expert by any means, but I've read that if you get the wrong oil or use too much of the right oil it can screw your watch. I used "moebius d5" that I got off ebay (see below). 1ml is more than enough. It is not technically the correct oil to use, but some experts chimed in that it was a little thicker so it would be less likely to spill elsewhere in the movement. Sounded perfect for a hack like me. Also, the thickness of the oil provides a little more friction so the rotor won't spin for 10 seconds after you move your wrist like mine did.
2. Remove a pin from the bracelet so you can get unobstructed access to the back of the watch.
3. Hack the movement then open the caseback. I used a sticky ball and it was easy to get off
4. Remove the three little screws in the very centre that hold the rotor in place. I used the red screwdriver.
5. Remove the rotor with a toothpick or rodicco, put it to the side and put the caseback back on (you don't need to fully tighten it, but you want to keep the dust out)
6. Flip the rotor over so you can see the underside (ie the side without the patek Philippe logo). You will see a gap with tiny little ball bearings (blue arrow) in it. That's where we want to lubricate to reduce the sound (red arrows)
7. Now we use the oil. You only need a teeny, tiny, incy, wincy bit. A drop would be way too much. Dip the tip of a toothpick in and scrape it over the edges of the bottle to remove most. Now dab the tip of the toothpick at 5 or so spots around that space over the ball bearings then spin the rotor for 30 secs using another toothpick (that doesn't have oil on it). Repeat that a few times. You can also oil the other side (green arrows) to try to get some oil in from both above and below.
8. After a few cycles of oiling and spinning, put the rotor back on, screw the screws back in (can be pretty fiddly), put the caseback on and see how it sounds. If it's still making too much noise, repeat steps 3-7 until you're happy.
9. Enjoy your quiet new nautilus.
