The Oysterflex Bracelet The 18 kt gold versions of the Cosmograph Daytona with a Cerachrom bezel are available with an Oysterflex bracelet. Developed by Rolex and patented, it singularly combines the robustness of a metal bracelet with the comfort of an elastomer bracelet. It is made up of two flexible curved metal blades – one in each bracelet section – overmoulded with high-performance black elastomer. For optimum comfort, the Oysterflex bracelet is equipped with cushions on its inner sides and an Oysterlock safety clasp to prevent accidental opening. Its length may be adjusted via the ingenious Rolex Glidelock extension system. 18 kt Everose Gold To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 kt pink gold alloy cast in its own foundry: Everose gold. Introduced in 2005, 18 kt Everose is used on all Rolex Oyster models in pink gold. --> Model availability All Rolex watches are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict Rolex production capacity and, at times, the demand for Rolex watches outpaces this capacity. Therefore, the availability of certain models may be limited. New Rolex watches are exclusively sold by Official Rolex Jewelers, who receive regular deliveries and independently manage the allocation and sales of watches to customers. Razny Jewelers is proud to be part of the worldwide network of Official Rolex Jewelers and can provide information on the availability of Rolex watches.
