Apple Watch Ultra 2 not turning on after swim

hi all, we was swimming with my Apple Watch Ultra 2 but after 5mins it started freaking out calling 911 and everything. After that it completely turned off and not turning on again what should I do. Disappointing that they advertise it as water proof. (I only swam for 5 min in not more than 0.5meters

The advertising is water resistant, not water proof.

I routinely swim with an Apple Watch, but expect damage or degradation will eventually allow a leak.


If you have AppleCare coverage, contact Apple. Otherwise, you’re headed for a replacement.

You can’t swim in 0.5 metres (19”). With the wild actions and overheating you mention in your other post I think it is more likely your watch developed a major electronic failure and the timing with water exposure is simple coincidence.


Advice: Arrange to get the watch examined by Apple Support. https://getsupport.apple.com
