The Rolex Oyster Deepsea Sea-Dweller, with its legendary 12,800 ft (3,900m) water resistance, represents the pinnacle of professional diving watches. This article delves deep into the history, features, specifications, and price of this exceptional timepiece, exploring its place within the broader Rolex Sea-Dweller lineage and comparing it to related models. Understanding the "цена" (price) requires a nuanced look at the market, considering factors like condition, year of production, and retailer.
A Legacy of Depth: The Rolex Sea-Dweller Family
Before examining the specific model in question, it's crucial to understand its place within the broader Rolex Sea-Dweller family. Rolex's commitment to creating robust and reliable diving watches dates back decades. The Sea-Dweller line, an evolution of the Submariner, was specifically designed to meet the demands of professional saturation divers. These individuals spend extended periods at significant depths, requiring a watch capable of withstanding immense pressure and offering exceptional reliability.
The original Sea-Dweller, introduced in 1967, already showcased Rolex’s dedication to pushing the boundaries of underwater exploration. Subsequent iterations refined the design and technology, constantly improving water resistance and functionality. The evolution led to the introduction of the Deepsea line, a testament to Rolex's relentless pursuit of technical excellence. The Deepsea models, including the Deepsea Sea-Dweller we are focusing on, represent a significant leap forward in diving watch technology.
The Rolex Sea-Dweller Deepsea: A Masterpiece of Engineering
The Rolex Oyster Deepsea Sea-Dweller 12,800 ft (3,900m) is not merely a watch; it's a testament to Rolex's mastery of materials science, engineering, and horological precision. Its impressive water resistance is achieved through a combination of innovative design features:
* Oyster Case: The iconic Oyster case, a hallmark of Rolex diving watches, provides exceptional protection. The monobloc middle case, screw-down case back, and Triplock winding crown combine to create an impenetrable barrier against water ingress. The case itself is crafted from high-grade 904L stainless steel, known for its exceptional corrosion resistance and scratch resistance.
* Ringlock System: This patented system is a key element in achieving the Deepsea's remarkable water resistance. A ring of nitrogen-alloyed steel within the case structure helps distribute the immense pressure evenly, preventing deformation and ensuring the integrity of the watch's internal components even at extreme depths.
* Crystal: The watch features a thick, scratch-resistant sapphire crystal, designed to withstand the immense pressure at depth. The crystal is carefully engineered to ensure clarity and prevent distortion, crucial for readability in low-light underwater environments.
* Helium Escape Valve: Saturation divers often work in pressurized environments using helium-oxygen mixtures. The helium escape valve allows helium gas to escape during decompression, preventing damage to the watch movement. This valve is a crucial safety feature for professional divers.
* Movement: The Deepsea Sea-Dweller typically houses a self-winding mechanical movement, renowned for its precision, reliability, and robustness. These movements are chronometer-certified, meaning they meet stringent accuracy standards set by COSC (Contrôle Officiel Suisse des Chronomètres). The specific caliber varies slightly depending on the year of production.
