Product Description
The Rolex Cosmograph Daytona 126500LN in black dial form is the purest expression of the modern steel chronograph. Understated, powerful, and instantly recognizable, this reference refines the legendary Daytona silhouette with subtle case updates and a next-generation movement—while preserving the DNA that made it one of the most coveted watches in the world.
Design & Case
Crafted from corrosion-resistant 904L Oystersteel, the 40mm case features refined lugs and a slimmer visual profile compared to its predecessor. The black Cerachrom ceramic bezel, engraved with a tachymetric scale, reinforces the Daytona’s racing heritage while offering exceptional scratch resistance and long-term color stability.
The glossy black dial delivers a sleek, monochromatic aesthetic. Contrasting snailed subdials enhance legibility and depth, while Chromalight hour markers and hands emit a long-lasting blue glow in low light conditions.

Powering the 126500LN is Rolex’s updated in-house Caliber 4131 automatic chronograph movement, offering:
-
Chronergy escapement for improved energy efficiency
-

-
Approximately 72-hour power reserve
-
Superlative Chronometer precision (−2/+2 seconds per day after casing)
The 4131 introduces upgraded finishing and a redesigned oscillating weight, representing the most technically refined steel Daytona to date.
