To ensure their precision and reliability, Rolex subjects every watch that leaves its workshops to a series of particularly demanding tests. When you purchase a Rolex watch, the authorized retailer will complete the Rolex warranty card and enter the date on it, certifying the authenticity of your watch.
All Rolex models come with a five-year warranty and are certified as a Superlative Chronometer, a status symbolized by a green seal. This exclusive designation attests that the watch has successfully undergone a series of specific final inspections conducted by Rolex in its own laboratories and according to its own criteria, in addition to the official COSC certification of its movement.
Each Rolex watch is presented in a magnificent green box, protecting and guarding the treasure it contains. The box also symbolizes the act of giving. If you're giving a watch, it's important that the recipient's first contact with their Rolex sets the tone for what lies within.

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 kilometers or miles.
Black dial
This model features a black dial with spray-coated counters, 18 kt 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.
Yellow Rolesor
Gold is coveted for its luster 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 Perpetual collection.

Model Availability
All Rolex watches are hand-assembled with the utmost care to meet the brand's high quality standards. Such high standards naturally restrict Rolex's production capacity.
Therefore, the availability of certain Rolex models may be limited. New Rolex watches are available exclusively from official Rolex retailers, who receive regular deliveries and independently manage the allocation of watches to customers.
Godechot Pauliet is honored to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of different models.
