I went through 3 Amazon stainless steel "Damascus" bands, $6 each. Either lost them, or wore them down to the point of looking like crap, or scratching them all to hell.
Now that I work with machines, a basic Amazon silicone ring, in case some spinning part grabs it.
I take it off every night, and usually don't bother on the weekends, unless I'm trolling for cougars at the bar
