Introduction: Centennial Tribute
The Rolex Cosmograph Daytona reference 126529LN marks the 100th anniversary of the 24 Hours of Le Mans in 2023. Produced for a single year with production appearing extremely limited (Rolex has not disclosed official numbers), this white-gold chronograph stands among the most notable modern Daytona releases.
White Gold Case Construction
The 40mm white-gold case keeps classic Daytona proportions while the precious metal changes the wearing experience. At 12.2mm thick and approximately 47.5mm lug-to-lug, it wears balanced across a range of wrists.
The case features Rolex's Oyster architecture—screw-down pushers, crown, and caseback—for 100 meters of water resistance. While not a dive watch, it’s suitable for daily water exposure, including swimming.
A subtle white-gold ring surrounds the bezel insert, creating separation between the black ceramic and the case body—distinct to this Le Mans execution while staying true to the Daytona design language.

Commemorative Cerachrom Bezel
The black Cerachrom bezel features a unique red “100” at the 70-mark position—a direct nod to the 100th anniversary of the 24 Hours of Le Mans. This single detail makes the bezel a commemorative statement, not just a functional tachymeter.
The red accent breaks the monochrome in precisely one spot, adding contrast while preserving overall balance. Rolex's Cerachrom resists scratches and color fade; the engraved tachymeter numerals are platinum-coated for long-term legibility.
Reverse Panda Dial with Paul Newman Cues
A high-gloss black lacquer dial with light subdials delivers the classic reverse-panda look. White-gold markers and hands maximize legibility and connect the design to mid-century racing chronographs.
The three subdials use square markers that echo the vintage “exotic” dial aesthetic associated with Newman-era Daytonas. These indices contrast with the main dial’s applied markers while nodding to history.
The 9 o’clock subdial is a 24-hour totalizer rather than the usual 12-hour counter. This mirrors the Le Mans race format, making the chronograph function race-specific. The red “DAYTONA” script above 6 o’clock ties into the bezel’s red “100.”
White-gold hands and markers receive luminescent coating for night reading. The design balances vintage inspiration with modern execution.
Caliber 4132 Movement
Rolex Caliber 4132 is a 4131 adapted with gearing for a 24-hour counter at 9 o’clock—showing Rolex will develop bespoke movements for special applications.
The movement offers ~72 hours of power reserve. Chronergy escapement and Paraflex shock absorption aid efficiency, robustness, and accuracy.
A sapphire display back—unusual on a Rolex sports model—shows Côtes de Genève finishing and an open-worked 18k gold rotor. This positions the Le Mans Daytona alongside other modern Rolex references with display backs, notably the platinum Daytona 126506 and the Perpetual 1908.
White Gold Oyster Bracelet
An 18k white-gold Oyster bracelet with polished center links contrasts against brushed outer links, adding visual depth without losing utilitarian character.
Each link shows meticulous finishing with consistent surfaces; the bracelet moves freely without excessive play, draping comfortably while staying secure.
The Oysterlock folding clasp includes the Easylink 5mm extension for quick, tool-free sizing adjustments.
