I have never scratched a watch so deeply
It might be something that bothers you too much given the location.
Audemars Piguet has top notch service centers and does offer refinishing services. There are limitations on how many times you can refinish, but that might pertain more to the main case and bezel. Your scratch appears contained to the bracelet. I suspect it can be restored without issue.
