While there is no "Polywatch" for this, there is something close, I'm happy to report. Recently picked up a bar of Jeweler's rouge made for hard, white metals (see link https://www.ebay.com/itm/Jewelers-Green ... 3949589403 ). I only wish I'd taken before/after pics! This stuff is legendary!

I didn't want to lose anymore of the plating than necessary, and so didn't use any buffer or machine, but instead put a bit on a soft felt rag, from a CD/DVD-buffing kit. I masked off an anodized part of the bezel with masking tape and then began working each of the effected areas lightly and with even, medium pressure. It only took a couple of minutes to see a serious improvement. When the rag started to look dark (from chrome removed), I did a second application and then a third, working it a few minutes each time. JUST EXACTLY what I'd hoped for! Still character there, but also a real shine that had been missing before. It takes patience, but will prove very rewarding.
