What we see are two end stones with powerful micro-magnets (about 1.3 teslas) that keep the balance staff centered, and even more, allows it to self adjust when the watch takes a shock. On top of that, the watch is completely anti-magnetic due the use of these micro-magnetic pivots, and the magnets don't impact the operations of the watch because all parts that would be affected are made of silicon. Clever, no?

One of the magnets is actually stronger than the other, so one end of the staff touches the end stone while the other "floats" just above the other end stone. So when a shock occurs, the magnets automatically re-center the balance staff. It also means that the friction on the balance staff pivots is pretty much the same no matter what position the watch is in. Essentially, this magnetic field is an artificial gravity that ensures the 7727's regulating organ to be working flawlessly in any position. Sound familiar? Maybe a little like a tourbillon? Not at all the same solution mechanically, but indeed the very same problem that needs solving, and in my opinion, the magnetic pivot is a far more interesting, thoughtful, and indeed commercially viable solution than the tourbillon. It's also so very much less "ugh, really?" than a tourbillon.
