A luxury watch is a multi-sensory object, and its case, dial, and bracelet are the canvases upon which brands demonstrate their mastery of materials. While 316L stainless steel is a workhorse, prized for its durability and understated elegance, the high-horology world often turns to more exotic substances.
904L steel, used almost exclusively by Rolex, offers a higher resistance to corrosion and a unique ability to take a exceptionally bright, mirror-like polish. Titanium provides incredible strength with featherlight comfort, ideal for large, tool-oriented watches.
