The way they positioned the tourbillon at 12 and the chrono not at 6, plus the large size of the tourbillon, works really well imho. It creates just the right amount of visual tension to keep the dial well balanced but interesting.
In terms of weight, the watch feels quite substantial on the wrist. Probably similar as my PP 5740 if this is any help. It is not a small watch, but the weight feels reassuring and proportionate rather than excessive.
