The Rolex Submariner, a name synonymous with diving prowess and enduring luxury, holds a legendary status in the horological world. This article delves deep into the specifications and details of the Rolex Submariner, often referred to as a "Datenblatt" (datasheet) in German, exploring its robust construction, iconic design, and the market surrounding this highly sought-after timepiece. We'll examine its key features, the materials used in its construction, and where to find various models, from new to pre-owned options.
The Uncompromising Build: A Deep Dive into Materials and Construction
The Rolex Submariner's legendary reputation isn't built on fleeting trends; it's forged in the crucible of meticulous engineering and the use of premium materials. Central to its resilience is the Oyster case, a hallmark of Rolex design. This robust construction provides exceptional water resistance, protecting the intricate movement within from the harsh elements. A key element of this case is the material itself: Oystersteel.
Highly resistant to corrosion, Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and aerospace industries. This isn't just any stainless steel; 904L boasts superior corrosion resistance compared to standard 316L stainless steel, a common choice for many other watch brands. This makes the Submariner incredibly resistant to saltwater corrosion, a crucial feature for a diving watch designed to withstand the pressures of the deep. The polished finish of the Oystersteel further enhances its elegance and resistance to scratching.
Beyond the case material, the Submariner's water resistance is further enhanced by the Triplock winding crown. This triple-sealed crown system ensures a waterproof seal, preventing water ingress even under significant pressure. The screw-down crown, combined with the sapphire crystal glass, forms a formidable barrier against the elements. The sapphire crystal, renowned for its scratch resistance, ensures the dial and hands remain clear and legible, even after years of wear.
The unidirectional rotatable bezel, a defining characteristic of the Submariner, is also crafted with precision and durability in mind. Graded in minutes, this bezel allows divers to accurately monitor their dive time. Its ceramic insert, known as Cerachrom, is exceptionally scratch-resistant and fade-resistant, ensuring the bezel markings remain clear and accurate throughout the watch's lifespan. This contrasts sharply with earlier models which used aluminum bezels, which were prone to fading and scratching over time.
The movement powering the Submariner is another testament to Rolex's commitment to precision and reliability. The caliber used varies depending on the specific model and year of production. However, all movements are known for their chronometer-certified precision, meaning they meet stringent accuracy standards. The self-winding mechanism, powered by the wearer's movements, ensures the watch runs continuously without the need for manual winding. Many modern Submariners feature the Calibre 3235, known for its extended power reserve and superior performance.
