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!!!
I am taller than most, so door handles are not my enemy. My scratches have come from utilizing wrong tool for the job. Camping with an edifice. Working on truck wearing my Orient diver. So, I am my watche’s worst enemy.
