The search term "Rolex Anker 1220" presents a fascinating challenge. A quick search reveals no readily available information about a specific Rolex model bearing this exact designation. The reference to "Rolex anchor" in the eBay advertisement likely points to a colloquialism or a misidentification. The anchor symbol, while not a standard Rolex model identifier, is sometimes used informally to refer to specific models, or perhaps even to describe the robust and reliable nature of the brand itself. The connection with the Sea-Dweller, suggested by the "ROLEX SEA DWELLER ANCHOR" phrase, provides a crucial clue. It is highly probable that "Rolex Anker 1220" is an inaccurate or informal reference to a Rolex Sea-Dweller, potentially of a specific reference number or featuring a particular detail misinterpreted as "Anker" (German for anchor).
This article will therefore delve into the world of Rolex Sea-Dweller watches, exploring the various models, their specifications, history, and significance within the Rolex lineup. We'll also examine related Rolex models mentioned in the prompt, focusing on their characteristics and what makes them desirable to collectors and enthusiasts.
The Rolex Sea-Dweller: A Deep Dive into History and Design
The Rolex Sea-Dweller, a direct descendant of the iconic Submariner, is engineered for professional saturation diving. It's a testament to Rolex's commitment to pushing the boundaries of watchmaking technology and reliability. Its robust construction, helium escape valve, and exceptional water resistance have made it a legend among divers and watch collectors alike. The Sea-Dweller's history is rich and multifaceted, with several iterations evolving over the years, each introducing innovative features and refinements.
Early Sea-Dwellers, like the reference 1665, were groundbreaking for their time, introducing the helium escape valve, crucial for preventing crystal damage during decompression after deep saturation dives. Subsequent references, such as the 16600 and 16660, refined the design and incorporated improvements in materials and movements. The modern Sea-Dweller, available in various iterations including the 43mm Sea-Dweller and the Deepsea, showcases Rolex's continued commitment to pushing the limits of diving watch technology. These models often feature a larger case size, enhanced water resistance, and improved movements, reflecting the evolution of diving technology and the demands of professional divers.
Exploring the Key Features of the Rolex Sea-Dweller:
* Helium Escape Valve: A crucial feature distinguishing the Sea-Dweller from the Submariner, this valve allows helium gas to escape during decompression, preventing damage to the watch crystal.
* Water Resistance: The Sea-Dweller boasts exceptional water resistance, typically exceeding 1,000 meters (3,300 feet), making it suitable for extreme depths.
* Oyster Case: The iconic Oyster case, a hallmark of Rolex, provides robust protection against water, dust, and shocks. This is reinforced by the Triplock crown system, ensuring watertight sealing.
* Calibre Movement: The Sea-Dweller is powered by highly reliable and precise self-winding movements, typically Rolex's in-house calibres, renowned for their accuracy and longevity.
* Materials: Rolex uses high-quality materials, including 904L stainless steel (Oystersteel) known for its corrosion resistance and durability, and sapphire crystals for scratch resistance.
