The Rolex Sea-Dweller Deepsea, specifically the 2009 model (reference 116660), represents a significant milestone in Rolex's dive watch history. Its robust build, impressive water resistance, and iconic design have cemented its place as a coveted collector's item and a highly functional professional dive tool. This article will delve into the specifics of the 2009 Deepsea, comparing it to its successors, examining its investment potential, and exploring its place within the broader context of Rolex's Sea-Dweller and Deepsea lines. We'll also touch upon relevant reviews and price guides to provide a comprehensive overview.
The 2009 Rolex Sea-Dweller Deepsea (116660): A Closer Look
The listing mentioned, priced at $8,722 for a 2009 model in good condition, provides a valuable starting point for our discussion. This price reflects the enduring demand for this particular reference. The 116660 boasts a 44mm Oyster case, significantly larger than its predecessors, constructed from virtually indestructible 904L stainless steel. This substantial size contributes to its impressive 3,900-meter (12,800-foot) water resistance, a testament to Rolex's engineering prowess. The Ringlock System, a crucial innovation introduced with this model, plays a vital role in achieving this exceptional depth rating. This system uses a hardened steel ring inside the case to distribute pressure evenly, protecting the movement from the immense forces at such depths.
The watch is powered by Rolex's calibre 3135, a self-winding mechanical movement known for its reliability and accuracy. The movement is COSC-certified, guaranteeing its precision. The dial is typically black, featuring large, highly legible luminescent hour markers and hands, crucial for underwater visibility. The unidirectional rotating bezel, also made of ceramic, ensures safe decompression during dives. The distinctive helium escape valve, positioned at 9 o'clock, allows for the controlled release of helium during saturation dives, preventing potential damage to the watch. The Oyster bracelet, comfortable and robust, completes the package, securely fastening the watch to the wrist.
Rolex Deepsea 116660 vs 126660: A Generational Comparison
The 116660 (2009 model) paved the way for the subsequent 126660, released in 2018. While both share the iconic Deepsea design, several key differences exist. The 126660 boasts an updated calibre 3235 movement, offering improved chronometric performance and a longer power reserve. The newer movement incorporates Rolex's Chronergy escapement and optimized blue Parachrom hairspring, enhancing shock resistance and precision. Aesthetically, subtle changes are present, including updated hands and markers, though the overall design language remains consistent. The 126660 also features a slightly redesigned case and bracelet, although the functionality and water resistance remain remarkably similar. The choice between the two ultimately depends on personal preference and budget. The 116660, while older, offers a compelling value proposition, representing a significant piece of Rolex history.
