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. The latest Explorer model’s characteristic 3, 6 and 9 numerals are now filled with a luminescent material emitting a long-lasting blue glow, like the hour markers and hands. Like all Rolex timepieces, the Explorer’s 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 Oysterlock folding clasp, which prevents accidental opening 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 calibre 3132, a self-winding mechanical movement entirely developed and manufactured by Rolex. It features a Parachrom hairspring and Paraflex shock absorbers, offering greater resistance to shocks and to extreme conditions. Like all Rolex Perpetual movements, the 3132 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
