- Free worldwide shipping
Bold, rare, and crafted from the cosmos—the Rolex Cosmograph Daytona Ref. 126518LN is a fusion of celestial material and high-performance chronograph engineering. Featuring a meteorite and black dial housed in 18 ct yellow gold, this reference stands as a tribute to both Rolex’s racing legacy and its mastery of materials rarely found on Earth.
Dial
The meteorite dial, cut from a genuine extraterrestrial rock that traveled through space before landing on Earth, exhibits its unique crystalline Widmanstätten pattern—no two dials are ever alike. Contrasted with black sub-dials, this layout offers exceptional readability and aesthetic drama. Applied hour markers and hands in yellow gold, filled with Chromalight, provide lasting luminescence and clarity in all conditions.
Case
The 40 mm Oyster case, rendered in solid 18 ct yellow gold, is both luxurious and robust. Its monobloc middle case and screw-down pushers deliver exceptional resilience, while the Cerachrom black ceramic bezel offers both scratch resistance and tachymetric functionality—ideal for high-precision speed tracking. Water resistance is guaranteed to 100 meters (330 feet) via the Triplock crown system.
Movement
This Daytona is driven by the Rolex Calibre 4131, a next-generation chronograph movement designed and built entirely in-house. Featuring a vertical clutch and column wheel, it offers smooth, precise stopwatch operation. Certified as a Superlative Chronometer, the movement runs with an accuracy of −2/+2 seconds per day and features a 72-hour power reserve.
Bracelet
Fitted with the ultra-comfortable Oysterflex bracelet, this model merges sportiness and elegance. The flexible metal blade is coated in high-performance elastomer, offering the durability of a metal bracelet with the comfort of rubber. The bracelet is secured with an 18 ct yellow gold Oysterlock clasp and features the Easylink comfort extension system for on-the-go adjustments.
Water Resistance
Thanks to its patented Oyster case and robust crown system, this model maintains 100 meters of water resistance, allowing for confident wear during active and daily life.
The Rolex Cosmograph Daytona Ref. 126518LN, with its meteorite and black dial, is more than a chronograph—it is a conversation piece forged in precious metal and celestial stone. Designed for the discerning collector and modern connoisseur, this watch embodies technical excellence, rare materiality, and bold design in one seamless execution.
