The Tachymetric Scale
With its tachymetric scale, three counters, and pushers, the Cosmograph Daytona was designed to be the ultimate timing tool for endurance racing drivers. The bezel features a tachymetric scale to read average speed over a given distance based on elapsed time. This scale offers optimal legibility, making the Cosmograph Daytona the ideal instrument for measuring speeds up to 400 units per hour, expressed in kilometres or miles.
Black Dial
This model features a black dial with snailed counters, gold applique hour markers, and hands with a Chromalight display—a highly legible luminescent material. The central sweep seconds hand allows for an accurate reading of 1/8 second, while the two counters on the dial display the lapsed time in hours and minutes. Drivers can accurately map out their track times and tactics without fail.
Yellow Rolesor
Gold is coveted for its lustre and nobility, while steel reinforces strength and reliability. Together, they harmoniously combine the best of their properties. A true Rolex signature, Rolesor has been featured on Rolex models since the early 1930s and was trademarked as a name in 1933. It is one of the prominent pillars of the Oyster collection.
