Silver dial
The dial is the distinctive face of a Rolex watch, the feature most responsible for its identity and readability. Characterised by hour markers fashioned from gold to prevent tarnishing, every Rolex dial is designed and manufactured in-house, largely by hand to ensure perfection.
Oystersteel
Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.


The Oyster bracelet
The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable. It is equipped with an Oysterclasp and the Easylink comfort extension link, also exclusive to Rolex. This ingenious system allows the wearer to increase the bracelet length by approximately 5 mm, providing additional comfort in any circumstance.

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 Jewelers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.
Meierotto Jeweler is proud to be part of the worldwide network of Official Rolex Jewelers and can provide information on the availability of Rolex watches.

The Oyster Perpetual Datejust is the archetype of the classic watch thanks to functions and aesthetics that never go out of fashion. This year, Rolex presents the Datejust 36 featuring new 'palm' and 'fluted' dial motifs. The palm motif evokes lush, vibrant tropical forests, while the fluted motif showcases the pattern found on a range of Rolex bezels that has become one of the brand’s signature esthetic styles.
