The Leather: Horween® Shell Cordovan Widely considered the finest leather in the world, Shell Cordovan is vegetable-tanned at Horween® over six months in roughly 100 mostly-manual steps — a process unchanged since 1905. Its dense fiber structure resists creasing, and it's self-polishing: a quick pass with a horsehair brush revives the glassy luster. How It Ages On a wrist, worn daily, shell transforms fast: black deepens to a glassy, from-within luster that no topcoat can fake. Little maintenance required — that's the point of shell. FAQ Will it fit my watch? Any watch with 20mm lugs — check the width between your watch's lugs or your current strap's stamp. How do I care for it? A quick pass with a horsehair brush brings back the shine — no product needed.
