Well the harshest environment for mine is being attached to me. Between my blinking nerve damage making my stupid arm spasm and whack off things and me not babying it, it's had a tough time.
It's been bashed or scraped against walls, wood, metal, concrete, glass (car window) and porcelain. It's been thrown across the room to land on a solid wood floor, smack into the television, against the wall and on more than one occasion a poor unsuspecting sleeping collie dog 😀
It's survived it all with nought but tiny hairline scratches in the shiny silver, which it'll get no matter what, it's a watch after all. The sapphire however is completely un-marked, still looks like it did on launch day.
So I guess I'm saying, just wear it like any other watch, it'll survive what any other watch will.
