I just sent my Samsung Watch3 (which is still covered under the 1-year warranty) as it stopped working, and this watch, which has this two special features (as per the manual): Water Lock mode when you exercise in the water and rated 5ATM and passed military specifications testing, IS NOT COVERED IF IT WETS WET!!!!
I have spent several hours over the phone, and the answer is the same. Not covered because it got wet!!! I don't recommend anybody to buy a Samsung watch trusting their specifications, I don't think I am going to trust this brand anymore.
Anybody can help you how do I file a claim under the Bureau of Consumer Protection?
