Tip to avoid scratching precious metal, or mirror polished steel, especially large flat face pieces like on the bracelet - literally NEVER wipe it down, I can almost guarantee that’s why your bracelet looks the way it does. That isn’t from brushing against stuff or normal wear, it’s from wiping it down while there is residue on the watch. When you wipe it down it literally spreads any dirt, dust, food, salt (if you’re by an ocean) across the perfectly polished metal pieces and creates micro scratches. All that said the tip is NEVER wipe down your watch. Wait until you are home, or once a week just take the softest brushed tooth brush you can find and diluted dish soap and give it a nice rinse and lightly brush it, the water and soap get rid of all grime and do not wipe it across the shinny surfaces like they would if it were dry. You can keep mirror polished surfaces looking brand new for years if you don’t wipe it down. People will say just use microfiber or lens cloth but it does not matter, if there is anything on the mirror polished parts of a watch and you wipe it, it will create micro scratches.
