I have experience with a few different metal bracelets on the Duro. I have a Casio branded one that is a cheap folded metal hair pincher of a thing, a mixture of polished and brushed that looks ok from 6 ft away. The other two are an Ali Express Jubilee style that fits well and is comfortable to wear, but my personal favourite is the oyster style bracelet from an Orient Kamasu that fits onto the Duro with minimum adjustment to the hollow end-links. I’ve swapped out the pressed clasps of those two for an Ali X milled clasp with 6 holes of microadjust. Very happy with both the Orient and Ali X straps, wouldn’t put the casio metal strap anywhere but the bin though.
