My Apple Watch died and never turned back on this summer because I wore it while swimming. I went to the Apple Store to get it checked they told me “oh, but you should have rinsed it after coming out of the sea because the salt deteriorated the water-resistant property. Since you are out of warranty, you can get it repaired for 300+€.” Mind you, it was an AW SE 1st gen.
