The Rolex Sea-Dweller Deepsea, particularly the blue dial variant from 2018 with serial number prefix LC100, represents a pinnacle of horological engineering and design. This article delves deep into the specifics of this particular model, exploring its history, technical features, market value, and what makes it a highly sought-after piece among collectors and enthusiasts. We will unpack the details surrounding the reference number 116660, examining its condition, year of manufacture, and the significance of the LC100 serial number prefix. Finally, we'll consider its place within the broader Rolex Sea-Dweller lineage.
The Legacy of the Rolex Sea-Dweller:
Before focusing on the specific 2018 LC100 model, it's essential to understand the Sea-Dweller's place within the Rolex pantheon. Born from the demands of professional divers, the Sea-Dweller's story is one of relentless innovation and unwavering commitment to reliability in extreme conditions. Initially conceived as a more robust and capable sibling to the Submariner, the Sea-Dweller quickly carved its own niche, becoming synonymous with deep-sea exploration and unparalleled water resistance. Its development involved close collaboration with professional divers, leading to technological breakthroughs that redefined the limits of underwater timekeeping.
The original Sea-Dweller, introduced in 1967, boasted a groundbreaking helium escape valve, a crucial feature for saturation divers working at extreme depths. This valve allowed the escape of helium gas accumulated during decompression, preventing the watch crystal from shattering under pressure. This innovation, coupled with its exceptional water resistance rating, cemented the Sea-Dweller's position as the ultimate tool watch for professional divers.
Over the decades, the Sea-Dweller has undergone several iterations, each reflecting advancements in materials science, manufacturing techniques, and design aesthetics. The evolution has seen improvements in water resistance, the introduction of new movements, and refinements in the case design. However, the core principles of robustness, reliability, and precision have remained constant throughout its history.
The Deepsea: A Giant Leap Forward:
The Rolex Sea-Dweller Deepsea, introduced in 2008, marked a significant leap forward in the evolution of the Sea-Dweller line. This model pushed the boundaries of what was considered possible in a wristwatch, achieving an unprecedented water resistance rating of 3,900 meters (12,800 feet). This remarkable feat was accomplished through innovative design and the use of high-strength materials. The Deepsea’s larger case size, compared to previous Sea-Dweller models, allowed for greater internal volume and the incorporation of advanced technologies needed to withstand the immense pressure at such depths.
The Deepsea's iconic design, with its bold and imposing presence, immediately captured the attention of watch enthusiasts. Its distinctive features, such as the Ringlock System—a patented internal ring that distributes pressure evenly across the crystal—further enhanced its rugged appeal. The case construction, utilizing high-grade 904L stainless steel, contributes to its exceptional durability and resistance to corrosion.
