Last night I rubbed my watch against the stainless steel handle on my oven. SB Ti S6. It left a mark that I can’t feel with my finger nail. Feels flush as can be. It wasn’t a hard rub, just grazed it as I was walking by. Didn’t expect it would’ve done damage to the sapphire glass as I’ve done much worse before. It looks like metallic material but can’t really tell if it’s oleophobic coating that rubbed off. Is there a cleaner and light abrasive that anyone recommends to try to remove it or leave it be? Thanks.
