The Rolex Deepsea Sea-Dweller, specifically the 2018 model in its striking blue dial configuration (reference 126660), stands as a testament to Rolex's unwavering commitment to pushing the boundaries of horological innovation and diving technology. This iconic timepiece, with its robust build and impressive water resistance, has captivated watch enthusiasts and professional divers alike. This article delves deep into the specifics of the 2018 Rolex Deepsea Sea-Dweller Blue, exploring its features, history, value, and where to find the best deals, particularly referencing the options available on Chrono24.
A Deep Dive into the Specifications:
The Rolex Deepsea Sea-Dweller 126660, released in 2018, represents a significant evolution in the Deepsea line. Its most immediately striking feature is its deep blue dial, a departure from the previous black dial versions. This vibrant blue is not just aesthetically pleasing; it's also highly legible, even in low-light underwater conditions. The dial's crispness is further enhanced by the Chromalight display, offering superior luminescence for extended periods.
Beyond the dial, the watch boasts a 44mm Oyster case, crafted from virtually indestructible Oystersteel. This robust material ensures the watch can withstand the immense pressures of the deep ocean. The case is fitted with a unidirectional rotatable bezel, crucial for tracking dive time, with a Cerachrom insert in ceramic. This ceramic bezel is highly scratch-resistant and impervious to the fading effects of ultraviolet radiation, maintaining its accuracy and appearance even after years of use.
The watch's heart is the caliber 3235, a self-winding mechanical movement entirely developed and manufactured by Rolex. This movement is a marvel of engineering, incorporating numerous innovations that enhance its precision, power reserve (approximately 70 hours), and resistance to shocks and magnetic fields. The movement's performance is meticulously tested and certified by COSC (Contrôle Officiel Suisse des Chronomètres), guaranteeing its accuracy.
The Deepsea's water resistance is truly exceptional, rated to an astounding 3,900 meters (12,800 feet). This remarkable depth rating is achieved through a combination of factors, including the robust case construction, the Triplock winding crown, and the helium escape valve. The helium escape valve is a critical feature for professional saturation divers, allowing helium gas to escape during decompression, preventing potential damage to the watch.
The bracelet is a solid Oyster bracelet with an Oysterlock safety clasp and Glidelock extension system. The Glidelock system allows for precise adjustment of the bracelet length, accommodating the changes in wrist size that can occur due to the effects of pressure at depth or the wearing of a diving suit. This ensures a comfortable and secure fit in all conditions.
The 2018 Model's Significance:
The 2018 release of the Deepsea Sea-Dweller Blue wasn't just a simple color change. It marked a continuation of Rolex's dedication to improving its already impressive diving watches. The introduction of the caliber 3235 movement represented a significant upgrade in terms of performance and reliability, solidifying the Deepsea's position as a top-tier professional diving instrument. The blue dial, while aesthetically pleasing, also enhanced readability in challenging underwater environments.
