The tachymetric scale

The tachymetric scale

With its tachymetric scale, its three counters and its 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.

White dial

This model features a white 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 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

Yellow Rolesor

Gold is coveted for its lustre and nobility. Steel reinforces strength and reliability. Together, they harmoniously combine the best of their properties. A true Rolex signature, Rolesor has 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.

Rolex Watches

Model Availability

All Rolex watches are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict Rolex production capacity and, at times, the demand for Rolex watches outpaces this capacity.

Therefore, the availability of certain models may be limited. New Rolex watches are exclusively sold by Official Rolex Retailers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.

Ethos Summit is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.

Rolex Watch

The emblematic style and superlative performance of the Oyster Perpetual Cosmograph Daytona have cemented its iconic status well beyond the motor racing circuits. To mark the 60th anniversary of the watch, Rolex ensures the legend lives on by revisiting the entire range, through high-precision reworking that concerns the case and face as well as the movement. The numerous adjustments and evolutions are a reminder that the pursuit of excellence is a race with no finish line.
