The Oysterflex bracelet, introduced on the Yacht-Master 40 in white gold, revolutionized rubber straps in luxury watchmaking. Unlike traditional rubber straps, the Oysterflex features a flexible titanium and nickel alloy blade running through its core, overmolded with high-performance black elastomer. This provides the comfort and sportiness of rubber with the security and adjustability of a metal bracelet.
The patented Oysterlock folding clasp is the same used on Rolex's metal bracelets, ensuring security, whilst the Glidelock extension system allows precise micro-adjustments. The Oysterflex is significantly more comfortable in warm weather than metal bracelets, doesn't pull wrist hair, and gives the Yacht-Master a more contemporary, sporty appearance.
It's also extremely durable—the elastomer compound is resistant to environmental damage and maintains its appearance over time. For anyone living in warmer climates or seeking maximum wearing comfort, the Oysterflex is genuinely superior to traditional bracelets.
