List or name whatever ends up messing up your watch. For me it’s ALWAYS DOOR HANDLES. Not when I use a door handle to open/close a door but more so walking past a door that’s already open my watch will brush against the handle scratching it slightly!!!
Because I wear quite big watches iv got used to moving my arm around door handles when I walk past them without even thinking about it but I have to say my watches worst enemy is by far my girlfriends jewelery / mobile phone
