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 dial is the distinctive face of a Rolex watch, the feature most responsible for its identity and readability. Characterised by hour markers fashioned from 18 ct gold to prevent tarnishing, every Rolex dial is designed and manufactured in-house, largely by hand to ensure perfection.
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.
This model is equipped with a new generation movement, calibre 3235, entirely developed and manufactured by Rolex for a superlative level of performance. Certified as a Swiss chronometer by COSC (Swiss Official Chronometer Testing Institute), it is tested a second time by Rolex after being cased to ensure that in everyday use it satisfies Rolex’s criteria for precision, which are twice as exacting as those for an officially certified chronometer. This control of the final precision of the assembled watch is carried out using a methodology and high-technology equipment specially developed by Rolex.
WHAT A DIFFERENCE A DATE MAKES
Influenced by the pioneering Datejust, the date on the Datejust 41 is displayed in a window at 3 o’clock and changes instantaneously. The Cyclops lens on the crystal, invented by Rolex in 1953, magnifies the date for easy reading.
