Found a Forerunner 955 on a beach

Yesterday was hiking on the cost and found this Garmin. At the fist look it was in a terrible condition

But then I brought it home, washed, let it dry and tried to charge it. Surprisingly it worked as nothing happened!

Not sure for how long it was in the sand, but the rubber body parts were sanded heavily, the screen protector was damaged, so I removed it. The main issue is that the buttons were stuck with the sand in them (worth some cleaning), but apart of that it's still working fine.

Now the question is who is this person who lost it?
