The Rolex Cosmograph Daytona Ref. 126518LN is a contemporary masterpiece that masterfully blends bold, modern aesthetics with Rolex’s legendary chronograph performance . This striking 40mm timepiece is forged from 18K yellow gold and features a high-contrast black Cerachrom ceramic bezel with an engraved tachymetric scale, offering a modern and durable interpretation of the classic Daytona . The highlight is its coveted, vibrant turquoise blue lacquer dial, often nicknamed the “Tiffany” dial, which provides a captivating backdrop to the black contrasting chronograph sub-counters at 3, 6, and 9 o’clock, creating a sharp and desirable visual identity . This colorful, high-impact design is paired with 18k gold applied hour markers and hands, which are filled with Chromalight luminescent material for optimal legibility . At its heart beats the advanced in-house automatic Caliber 4131, a COSC-certified Superlative Chronometer movement that delivers an impressive 72-hour power reserve, a column-wheel vertical clutch chronograph mechanism, and a blue Parachrom hairspring for exceptional shock and magnetic resistance . The watch is secured on a sporty and comfortable black Oysterflex bracelet—a high-performance rubber strap with a titanium and nickel alloy core—fitted with a yellow gold Oysterlock folding clasp and the Glidelock extension system for a precise and secure fit . With 100 meters of water resistance and a screw-down crown, this 2025 release is the ultimate statement for the discerning collector, offering a perfect fusion of contemporary color, precious metal luxury, and chronograph performance . Key specifications: 40mm 18K yellow gold case; black Cerachrom tachymeter bezel; turquoise blue lacquer dial with black sub-dials; Rolex Caliber 4131 automatic movement; 72-hour power reserve; black Oysterflex strap with yellow gold Oysterlock clasp; 100m water resistance; sapphire crystal.
