Hi,
I think pictures of the case would help all of us to give you an opinion.
kind regards Max
It's absolutely down to you, really. If you're preping it for sale then unless it's awful, less is more IMHO, i.e. leave it alone. But if you're wearing it and it bugs you, then have it done. I'm surprised STS didn't bring it back to as-sold, as they are pretty good (depends on the condition before and what they were asked to do, of course). My eyes always go to the dial on mine so I ignore the case scratches, but a restored barrel case can look amazing. Some photos would help. Cheers.

Your case work would have been done before STS got their Lapping machine. I don’t think they quite reach the levels of LA Watchworks or Lewis watch co. but they can certainly refinish the case to a good level now. Perhaps it would be easiest to return it to them?
Rocco Manfredi at Watchworks in Bristol has one. I had a few cases lapped by him about 5 or 6 years ago when he first bought the equipment.
This is bad. The watch has been ground to death. Look how high the crystal sits. A MKII case should have a nearly flush crystal. Only the bevel should be showing.
