As a longtime watch enthusiast, I can confirm that there is a possible detriment to polishing too much/too often. I've seen it done to rolexes, where yes the surface is blemish free and shiny as heck but when you look at it from any angle or moving it a bit, you'll see that the reflections are odd, kind of wavy. What you can do is make the surface of the watch slightly uneven and it'll be apparent when light shines on it while it's moving. This especially happens when you polish out an individual blemish, or a certain area harder or more often than the whole watch. It's asinine to polish a watch more than like twice a year at the most; if you're that much of a perfectionist, be more careful with your watch! I've had my SS apple watch since 4/24 and it has zero blemishes or dings or scratches despite daily 12 hour wear.
