I can only comment on three of them. I’ve owned a Royal Oak, Aquanaut and handled a Piaget. Maybe an unpopular opinion but I’d rank them AP, Piaget, Patek. The Royal Oak is a tremendous watch with outstanding finishing and feels more substantial than it’s size. The Piaget is not far off but has a few sharp edges which could do with a bit more polishing. The Aquanaut is a watch that I tried to love but I ended up agreeing with the popular opinion before it became a must have piece that it’s not a real Patek. It tries to look sporty but is too light and the finishing is only on a par with a mid-market brand. I had both the strap and bracelet for mine and the bracelet was nothing better than you would find on a Seiko, and not even a Grand one! Traded mine for a complicated Patek and you can really see the difference in quality.
