Thanks for your reply!
My question more precisely relates to how the bracelet would conform to my wrist actually, whether the integrated bracelet would stand away from wrist at either side of the case, (dreaded bracelet gap).
To add to this - I just tried on my PPF 5726, perpetual calendar Nautilus on bracelet, and the bracelet curves to my wrist pretty well, there is a small gap on either side of the case, but not too bad.
So I'm just being cautious before I buy.
