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!!!
The metal clasp on my wife’s purse, or worse, her engagement ring. Waiting for the day that the diamond scratches the sapphire glass, but so far it’s only scratched bezels, case, etc…I keep forcing myself to walk to the right of her but it’s not always possible.
