No deployant clasp. No sailcloth texture. No complication. Just the material that serious dive straps are made from, cut in the shape that dive watches have worn since the 1960s. On the Black Bay, this is the strap that matches the watch's original intent. A tool watch on a tool strap.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFKM is the material standard for high-performance rubber. The same class of compound used in aerospace seals and industrial environments where standard rubber cracks, hardens, and fails. It resists UV exposure, saltwater, heat, sweat, and daily abrasion without fading or degrading. Standard rubber ages. FKM does not. On a Black Bay rated to 200m, the strap handles everything the case can.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe straight-end profile sits clean against the Black Bay case with a minimal, functional look. No curved ends. No integrated fit. Just a clean lug-to-strap transition that suits the Black Bay's no-nonsense tool watch character. It is lighter than the factory bracelet, more breathable than leather, and more comfortable in warm conditions than any metal option.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTen colourways. Black is the default. Navy pairs naturally with the BB58 Blue and the GMT Pepsi bezel. Green complements the BB58's gilt accents and the emerging green dial references in the Tudor lineup. Grey works across silver and black dials. Orange and red are for sport and contrast. Dark brown and beige add warmth for casual wear. White is the statement option on dark-dial references.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eQuick-release spring bars pre-installed for tool-free strap changes.
