Rolex builds its rubber bracelet in one colour and one colour only, so a fresh black FKM strap is the most faithful way to bring a worn or ageing Oysterflex back to its original, just-unboxed condition — at a fraction of a factory replacement, and with no compromise on feel.\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePremium FKM rubber — resists sweat, water, sunscreen, chlorine and UV; won't fade or crack\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDirect Oysterflex replacement for gold Daytona, Yacht-Master \u0026amp; Sky-Dweller\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eKeeps your original Rolex clasp — connects to the factory Oysterlock\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSpring bars included (your original Rolex spring bars also fit)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTwo-piece, made-to-fit — 20 mm or 21 mm lug width; each side in 50 \/ 60 \/ 70 mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLifetime warranty \u0026amp; free worldwide shipping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eCrafted from premium FKM fluoroelastomer — the same high-performance rubber trusted in demanding marine and aerospace use — this strap is built to outlast everyday wear. It shrugs off sweat, water, sunscreen, chlorine and UV, stays soft and supple on the wrist, and holds its colour and matte finish for years. The result feels every bit as premium as the watch it's made for.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis is a faithful, straight-end replacement for the Rolex Oysterflex bracelet. In a 20 mm lug width it fits the Cosmograph Daytona and Yacht-Master 40; in 21 mm it fits the Yacht-Master 42 and Sky-Dweller. It's designed to connect to your original Rolex Oysterlock clasp, so you keep your factory clasp and simply refresh the rubber. Every strap ships with spring bars included, and your original Rolex spring bars fit perfectly too. Thanks to the straight-end design, it also works on other Rolex sport models sharing the same 20 mm or 21 mm lug width — including the Submariner, GMT-Master II and Sea-Dweller — so just match your watch's lug width.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eLike the original Oysterflex, the strap is supplied as two separate pieces, and you choose the length of each side independently — 50 mm, 60 mm or 70 mm per side — for a precise fit on any wrist. Just select your lug width (20 mm or 21 mm) and the two lengths you need. Many owners pair one longer side with one shorter side to centre the clasp; if you're replacing an existing Oysterflex, simply match your current lengths.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eEvery Helvetus strap is backed by our lifetime warranty against manufacturing defects and ships with free worldwide delivery and no import duties — the same quality and after-sales care trusted by more than 45,000 watch owners worldwide.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cem\u003eHelvetus is an independent brand and is not affiliated with, authorised by, or endorsed by Rolex.
