High-performance chronograph

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.

With chronograph counters

This model features a black dial with spray-coated counters, 18 ct gold applique hour markers and hands with a Chromalight display, a highly-legible luminescent material.

The dial allows drivers to accurately map out their track times and tactics without fail.

A meeting of two metals

Gold is coveted for its lustre and nobility. Steel reinforces strength and reliability. Together, they harmoniously combine the best of their properties.

A true signature, Rolesor has featured on models since the early 1930s, and was trademarked as a name in 1933. It is one of the prominent pillars of the Oyster Perpetual collection.

Alchemy of form and function

The design, development and production of bracelets and clasps, as well as the stringent tests they face, involve advanced high technology. And, as with all the components of the watch, aesthetic controls by the human eye guarantee impeccable beauty.

The Oyster bracelet is a perfect alchemy of form and function. First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection.
