Rolex uses Oystersteel Perpetual 36for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, superalloys 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 is a perfect alchemy of form and function, aesthetics and technology. First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection. For the Oyster Perpetual models the Oyster bracelet is fitted with an Oysterclasp.
This model is equipped with calibre 3130, a self-winding mechanical movement entirely developed and manufactured by Rolex. Like all Rolex Perpetual movements, the 3130 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. It is fitted with a Parachrom hairspring, offering greater resistance to shocks and to temperature variations. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
Few companies have been so consistently identified with the pursuit of excellence, the quest for the absolute, the discovery of original approaches and innovative solutions. Rolex watches have proved themselves from the start in the most extreme conditions imaginable – from the depths of the deepest oceans to the summits of the highest mountains, in the air and on the race track. And to ensure that all Rolex watches can live up to these high expectations, every single one is tested to extremes before it is allowed to leave the Rolex site.
