Isn't it the same exact movement as the 15300? As such, I would think whatever incidents are reported are the definite exception, since the movement has been around for some time.
Unless somehow the extra weight of the bigger watch is throwing it out of balance and AP didn't account for that? (I have zero technical knowledge to know if that's even possible - just a pure guess
