Developed and patented by Rolex, the outer construction of the Oysterflex is made of high-density elastomer, a material commonly used for high-performance bushings of cars. At its core is a flexible titanium-nickel alloy, giving it shape and structural integrity. With the two materials combined, the Oysterflex boasts of the same durabiity of a metal bracelet, with the comfort of a rubber strap.
Another strength of the Oysterflex is comfort: it features a tiered design that lifts the watch up and away from the wrist, providing airflow and comfort, which are commonly lacking from other sport bands.
What’s more, it also features the Rolex Glidelock extension, a system developed by Rolex, which allows fine adjustment of the bracelet length by 15 mm, without the use of tools.
