The Yacht-Master’s new Oysterflex bracelet, developed and patented by Rolex, offers a sporty alternative to metal bracelets without compromising robustness, waterproofness or reliability. Aesthetically and in suppleness and comfort, it resembles a rubber strap, while its resistance is comparable to that of a metal bracelet. The bracelet attaches to the watch case and the Oysterlock safety clasp by a flexible titanium and nickel alloy metal blade. The blade is overmoulded with high-performance black elastomer which is particularly resistant to environmental effects, very durable and perfectly inert for the wearer of the watch. For enhanced comfort, the inside of the Oysterflex bracelet is equipped with a patented longitudinal cushion system that stabilizes the watch on the wrist. The bracelet is fitted with an 18 ct Everose gold Oysterlock safety clasp that prevents accidental opening.
