The Rolex Yacht-Master 42 in 18 ct yellow gold on the Oysterflex bracelet is a striking blend of luxury and sportiness. This model features a 42 mm Oyster case crafted from 18 ct yellow gold, complemented by a matte black Cerachrom bezel insert and a black dial with Chromalight luminescent markers for enhanced legibility. The Oysterflex bracelet combines the durability of a titanium-nickel alloy core with the comfort of a high-performance elastomer overmold, secured by an 18 ct yellow gold Oysterlock clasp equipped with the Glidelock extension system for tool-free adjustments
