Do a search on the forum of "Cape Cod Cloth". These things are the best way to get a mirror polish back on your watch. I've used then to remove the hair scratches and they work extremely well. Just remember to go slow and use tape over the brushed surfaces as the Cape Cod Clothes are only for the mirrored bits (I use tape, others might have a steadier hand).
Like John said this wouldn't be something to be concerned about, unless your either King Kong or the Hulk.... :laugh: :laugh: All polishers remove surface metal. Otherwise they wouldn't polish as it's the only way to get the scratches 'even' with the rest of the bracelet.
You just don't want to put alot of pressure into it. Start light & see how it goes. Add pressure slowly as needed. Patience is a good thing when polishing your watch.. Just make sure you tape off the brushed links. Otherwise you'll probably polish them a bit too.
