Mens stainless steel bracelet with Coumadin engraved on inside.

This is a mens preowned stainless steel bracelets with a little red accent logo which I don’t know what that is and also has Coumadin engraved on inside. If anyone knows what that little red symbol means, please comment so I can update it. See pics. Not sure if that was someone’s name or a brand. It’s been cleaned beast I could and still a nice bracelet to own. Sold as is.
