How Rolex conquered the deep. For the conquest of the deep, The ultra-resistant divers’ model engineered by Rolex. It is the result of decades of collaboration with diving professionals, waterproof to a depth of 4,000 feet (1,220 metres) for the Sea-Dweller and 12,800 feet (3,900 meters) for the Rolex Deepsea.
Model features: Rolex adopts 904L stainless steel for its steel watch cases. A superalloy, 904L is extremely resistant and highly polishable. It is usually said that 904L is mainly used in the high technology, aerospace and chemical industries, at which maximum resistance to corrosion is essential. It can keep its beauty even in the worst environments.
It is equipped with an Oysterlock clasp, which prevents accidental opening, and an ingenious Glidelock, allowing fine adjustments of the bracelet without using any tools – and allowing it to be worn and comfortably over a diving suit. The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable.
It is characterized by hour markers which is fashioned from 18 ct gold to prevent tarnishing, and besides, every Rolex dial is designed and manufactured in-house, largely by hand to ensure perfection. The dial is the different face of a Rolex watch, and the feature is most responsible for its identity and readability.
This model is equipped with calibre 3135, which is a self-winding mechanical movement entirely developed and manufactured by Rolex. Just like all Rolex Perpetual movements, the 3135 is a certified Swiss chronometer, which is a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. The 3135 has the feature of 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.
