Apple Watch in my home according to “Find my”

Hey 😌

Unfortunately, my apple watch was probably lost in the ocean while I was surfing (it was original strap..

The thing is that I can't remember if that's the case or maybe something else happened before I got out and saw that the watch is not on my hand.

This is series 6 with cellular and I kinda sure the cellular was ON while it lost.

So in the Find my App I can see that watch is exactly in home address somewhere and it is also keep updating on the location every day!

So an apple representative told me that the watch apparently remember his last location which is my house..

Is there any way to check if before I arrive home the watch was on the beach through his location?

The situation is disappointing me so much and I wish it is true and maybe I just need to do everything I can to find it somewhere here, or just to expect the fact it drowned in the water for good.

Sorry for all the words, but do you guys know if it is even make sense that the watch location still updating even though it is 100% without battery?

Thank you so much!

TLDR: 99 % lost my watch at beach, it’s have cellular and I guess it was ON.

Now the location keep showing me the watch is in my house 😳

BTW: Are there any recommend bands for this type of activities?
