Rolex Yacht-Master Oysterflex Black Rubber Strap 21mm

A genuine Rolex Oysterflex rubber strap, sold as an individual OEM component. Made from Rolex's own high-performance elastomer with a metal-reinforced core, finished to the exact fit and flex of the case. The underside features a longitudinal cushion system — small fins that stabilize the watch on the wrist and allow air to circulate for comfort in warm weather. The elastomer resists UV exposure, saltwater, sweat, and temperature swings far better than leather, and won't fade or crack like ordinary rubber. Available in four factory sizes.
