The Rolex Cosmograph Daytona M116508 Series is a celebration of luxury performance, precision engineering, and timeless motorsport heritage. Crafted entirely in 18ct yellow gold, the M116508 lineup embodies the bold, sophisticated essence of the legendary Daytona collection. Whether you prefer the now-iconic green “John Mayer” dial, deep black, radiant champagne, or other exclusive configurations, each model in the M116508 series offers exceptional value for collectors and enthusiasts alike.

At the heart of every M116508 reference lies a 40mm Oyster case in solid yellow gold — striking in presence, flawless in finishing, and built for endurance. The monobloc middle case is matched with a screw-down caseback and Triplock winding crown, delivering a water resistance of up to 100 meters (330 feet). The case proportions are carefully designed for a comfortable yet commanding wrist presence, ideal for both formal wear and everyday luxury.

The fixed bezel, also rendered in 18ct yellow gold, features a classic tachymetric scale — a signature Daytona element used for calculating average speeds over a measured distance. The engraved numerals and markers on the bezel are cleanly executed, offering both visual character and functionality.

Dial options in the M116508 series are as varied as they are desirable. Among the most coveted is the metallic green sunburst dial, made famous by musician and collector John Mayer. This variant pairs luminous gold hands and markers with a stunning reflective green surface and champagne gold-rimmed sub-dials. Other references in the series include black dials with contrasting gold sub-dials, champagne dials for tonal elegance, and white or mother-of-pearl variations for a refined look.

Every dial maintains the Daytona’s tricompax layout: 30-minute counter at 3 o’clock, 12-hour counter at 9 o’clock, and small seconds at 6 o’clock. All hands and markers are coated in Chromalight, Rolex’s proprietary blue-glow luminescent material for high legibility in low-light conditions.

Powering the M116508 series is the robust Rolex Caliber 4130, one of the most respected chronograph movements in the industry. This self-winding mechanical chronograph movement is engineered in-house and features a vertical clutch and column wheel for smooth stopwatch engagement. With a Parachrom hairspring and Paraflex shock absorbers, it’s built to withstand shocks, magnetic fields, and daily wear with unshakable reliability.

The movement delivers a 72-hour power reserve and is officially certified as a Superlative Chronometer, boasting an accuracy rating of -2/+2 seconds per day — double that of standard COSC certification.

The M116508 is paired with a matching 18ct yellow gold Oyster bracelet, offering a perfect balance of style and security. The bracelet features a solid-link construction, polished center links, and an Oysterlock clasp with the Easylink extension system, allowing for a 5mm quick adjustment for enhanced comfort.

This reference is not just a watch — it’s an enduring symbol of Rolex’s elite watchmaking, making the Daytona M116508 one of the most prestigious and sought-after chronographs in the world.
