Aftermarket Oysterflex straps for Rolex — the rubber-over-metal band Rolex fits to the Yacht-Master and Daytona, recreated here for the Submariner, GMT-Master and Datejust as well. Our Oysterflex-style straps use high-performance FKM rubber over a flexible metal core, with curved end links that lock into the case for a seamless, no-gap fit in 20mm and 21mm. Sporty, water-ready and comfortable — the modern Rolex look without the boutique price. Choose your fit below.
