In 1967, the famous independent watch brand Rolex launched the first Oyster Perpetual Sea-Dweller diving watch. It has become the ideal wrist choice for many people. In 2018, after the tremendous success of the brand’s 2017 launch of the red-letter sea ambassador, Rolex once again injected fresh blood into this legendary series at the annual Basel Watch and Jewellery Fair, with the deep “D-BLUE” black and blue two. The color dial face is presented with an Oyster case. It is worth mentioning that, in addition to slight changes in details, the brand-new DEEPSEA (deep diving type) is equipped with the 3235 movements for the first time. An upgraded version of the 3135 movements brings more excellent performance. It fully reflects the superb watchmaking craftsmanship of Rolex.
As the most sophisticated diver’s watch in the Rolex brand, the Rolex Sea-Dweller is water-resistant to 4,000 feet (1,220 meters), while the brand’s deep dive watch is water-resistant to 12,800 feet (3,900 meters). It far exceeds the waterproof level of most diving watches on the market, showing the extraordinary results of decades of cooperation with professional divers. In addition to inheriting the waterproof performance of this series, the new timepiece introduces a D-BLUE color dial in appearance, paying tribute to James Cameron’s historic single-person diving record. The two-tone dial changes from bright blue to deep black, representing the diving from shallow to profound. It has a unique look and feels and is immersive.
The new-generation 3235 movements are developed and manufactured by Rolex, demonstrating the brand’s innovative and excellent watchmaking technology, equipped with Rolex’s new patented Chronergy escapement. Made of nickel-phosphorus, it is not only efficient and reliable but also free from magnetic field interference, ensuring the accuracy of travel time. As one of the essential parts of the watch, the balance spring assembly is equipped with a Rolex blue Parachrom hairspring, made of a unique paramagnetic alloy cast by the brand. Its shock resistance is ten times higher than that of a traditional hairspring. The Rolex end coil ensures that the balance spring remains regular in any position. In general, the new movement has been significantly improved in terms of accuracy and reliability, power reserve, anti-vibration, anti-magnetic, and practicality. It is also a benchmark for quality movements in the future.
The new deep-diving watch is made of Oystersteel (a type of 904L steel) with a diameter of 44 mm. The lugs and the outside of the case have been redesigned to match the wide Oyster strap and the corresponding Oyster. Insurance discounts are integrated, showing a unique classic aesthetic while inheriting extraordinary waterproof performance. One side of the case is equipped with a helium escape valve device unique to diving watches to reduce the impact of pressure during diving.
There are three waterproof rings in the three-button winding crown, which, together with the waterproof devices on both sides, ensure the watch’s airtightness and the perfect waterproof performance of the case. Equipped with a unidirectional rotating outer ring and a black Cerachrom 60-minute graduated word ring on the outer ring, divers can master the diving and decompression time at the bottom of the sea to ensure driving safety.
The dial adopts the iconic Rolex diving hour markers and the central three-hand design, which is covered with an easy-to-read Chromalight long-lasting blue luminous material, which can read even in darker environments or when diving deep into the water. Very reliable.The back cover is designed with a dense bottom process, which, together with the case, ensures the extraordinary waterproof performance of the watch—equipped with an Oysterlock safety clasp to prevent accidental opening of the buckle, adding a sense of security. Features a dual extension system to adjust the chain straps when wearing heavy wetsuits.
