The Rolex Deepsea Sea-Dweller, model number 136660 from 2023, is an impressive evolution in Rolex's range of professional diving watches. This model represents exceptional robustness and technological innovation specifically tailored to the needs of deep-sea divers. The Deepsea is known for its extreme water resistance and advanced technical features that set it apart from other diving watches. Design and aesthetics: Dial: The Deepsea dial is traditionally designed to be very clear and functional for optimal underwater legibility. It features large, luminous hour markers and prominent hands coated with a luminous material so they remain clearly visible even in the dark depths of the ocean. The dial is often finished in classic black, which further improves contrast and legibility. Case: The Deepsea's case is made from Oystersteel, a stainless steel alloy known for its exceptional corrosion resistance and durability. With a diameter of approximately 44mm and a particularly strong sapphire crystal, the case is robust and ready for the extreme conditions of the deep sea. The Deepsea also features a helium valve that allows helium to escape during the decompression process in saturation diving environments, thus aiding pressure equalization. Technical features: Movement: At the heart of the Deepsea is the Rolex Caliber 3235, an advanced automatic movement with a power reserve of approximately 70 hours. This movement is known not only for its precision, but also for its robustness and reliability, even under extreme conditions. Water resistance: The Deepsea is water resistant to a depth of 3,900 meters (12,800 feet), making it one of the most powerful watches in the world of deep-sea diving. This exceptional water resistance is made possible by Rolex's innovative Ringlock system, designed for extreme pressure conditions. Bracelet: The bracelet is also made of Oystersteel and features the Rolex Glidelock and Fliplock extension systems, which allow quick and easy adjustment of the strap length over the diving suit without the need for tools. The 2023 Rolex Deepsea Sea-Dweller 136660 is the ultimate choice for professional divers and adventurers who need a watch that can withstand the harshest underwater conditions. Its combination of technological innovation, extreme performance capabilities and classic Rolex design makes it a sought-after model for watch lovers and professionals alike.
