Yeah my lifehack in that department is assuming that the seals might not be perfect anymore. Plus a brief brush with seawater splashes made my iPhone speaker sound like crap for a few days a few years ago so I've decided it's not worth the risk!

Seawater destroys everything you ever loved and cared for, no IP rating will defend against that for long.

I have never had a (smart)watch damaged by seawater. (I am not a sailor though, I guess keeping exposure fairly short matters.)

If my phone gets dirty watered, i ensure I rinse it with fresh water; really confuses the onlooker.
