The Rolex Sea-Dweller reference 16660, affectionately known as the "Triple Six" among collectors, holds a significant place in the history of professional diving watches. Its evolution, features, and enduring appeal make it a highly sought-after piece, commanding substantial prices in the secondary market. This article delves into the fascinating history of the 16660, exploring its design, technological advancements, and its lasting impact on the world of horology. While the provided unrelated text about Daytonas, Bulgari collaborations, and counterfeit watches (indicated by "triple aaa Rolex") is irrelevant to the 16660's history, we will focus solely on the subject at hand.
Origins and Evolution:
The 16660's lineage can be traced back to the original Rolex Sea-Dweller, reference 1665, introduced in 1967. The 1665, itself a significant advancement in diving technology, pushed the boundaries of water resistance and depth rating. However, the 1660, introduced in 1988, marked a significant leap forward. This new generation incorporated several crucial updates reflecting the ever-evolving demands of professional divers and Rolex's relentless pursuit of innovation.
One of the most notable changes was the introduction of the helium escape valve. The original Sea-Dweller lacked this crucial feature, making it less suitable for saturation diving. Saturation diving involves spending extended periods at significant depths, exposing the watch to high pressures and helium gas used in the decompression process. Without a helium escape valve, the pressure differential could cause the crystal to shatter or the case to deform. The 16660's helium escape valve, positioned at 9 o'clock, elegantly addressed this issue, allowing helium to escape during decompression, preventing damage to the watch.
Beyond the helium escape valve, the 16660 also featured a redesigned case. While maintaining the robust and reliable characteristics of its predecessors, the case offered subtle yet significant improvements in terms of ergonomics and wearability. The slightly larger case size, compared to the 1665, provided improved comfort and visibility.
The dial and hands also underwent refinements. The 16660's dial is instantly recognizable, often featuring a matte black finish with luminous markers and hands. The text, including the "SEA-DWELLER" inscription and the depth rating, is meticulously applied, showcasing Rolex's commitment to both functionality and aesthetics. While variations exist, the overall aesthetic remains consistent with the brand's signature understated elegance.
Movement and Reliability:
The heart of the 16660 is its robust and reliable movement. The calibre 3035, a self-winding mechanical movement, powered this iconic timepiece. Known for its accuracy, durability, and resistance to shock and magnetic fields, the 3035 movement has become synonymous with Rolex quality. Its robust construction ensured the watch's ability to withstand the extreme conditions encountered in professional diving. Regular servicing, as with any mechanical watch, maintains the movement's optimal performance and longevity.
