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.

Ceramic Bezel and Luminescent Display
The 60-minute graduated, unidirectional rotatable bezel of the Sea-Dweller enables various to precisely and safely monitor their dive and decompression times. It is equipped with a patented black Cerachrom bezel insert manufactured by Rolex in a virtually scratchproof ceramic whose color is unaffected by ultraviolet rays. The graduation is coated via PVD (Physical Vapor Deposition) with a thin layer of gold. The sleek black dial features large Chromalight hour markers and hands, filled with luminescent material that emits a long-lasting blue glow for excellent legibility in dark conditions.
Intense black dial
The black dial of the Sea-Dweller has the large hands and indices reserved for Rolex professional models. The dial bears the name Sea-Dweller inscribed in a yellow hue, echoing the color of the yellow gold. When the Sea-Dweller was updated in 2017, this lettering was in red, in reference to the original model. The innovative Chromalight display on the dial pushes back the boundaries of visibility in dark environments. Its distinctive blue glow lasts up to eight hours with a uniform luminosity, practically twice as long as that of standard luminescent materials.
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.
Auberi is honored to be part of the worldwide network of Official Rolex Retailers and will be able to provide you with information on the availability of different models.
