Rolex Deep Sea Dweller 116660 2018 Discontinued [Preowned]

Overview 

The Rolex Deepsea reference 116660 is a monumental feat of mechanical engineering, designed to conquer the "final frontier" of Earth’s oceans. Introduced in 2008, this reference pushed the boundaries of the Sea-Dweller lineage to unprecedented heights, offering a professional depth rating of 3,900 meters (12,800 feet). It is a watch of extremes, built for the uncompromising demands of saturation diving and the crushing pressures of the abyss. Following a decade of production, the 116660 was discontinued in 2018, making this specific example one of the final pieces produced before the transition to the 12-series—a significant detail for collectors seeking the ultimate iteration of this modern classic.

The cornerstone of the 116660 is the patented Ringlock System. This innovative case architecture features a high-performance nitrogen-alloyed steel central ring, a 5.5mm thick domed sapphire crystal, and a Grade 5 titanium caseback. This combination allows the 44mm Oystersteel case to withstand over three tons of pressure without the bulk of a traditional heavy diver. At 9 o’clock, the signature helium escape valve acts as a safety feature for decompression, ensuring the watch remains a functional tool for professional saturation divers.

The deep black dial is a masterclass in high-visibility design, featuring the Chromalight display, which emits a long-lasting blue glow in the darkness of the depths. This is framed by a unidirectional rotatable bezel with a Cerachrom insert in black ceramic, featuring graduations coated in a thin layer of platinum. Despite its formidable size and 17.7mm thickness, the Deepsea maintains a balanced aesthetic, serving as a powerful statement piece for those who appreciate technical ambition and a substantial wrist presence.

The 116660 is fitted with a robust Oyster bracelet that includes two critical adjustment features: the Rolex Glidelock system, allowing for 20mm of micro-adjustments in 2mm increments, and the Fliplock extension link, which adds an additional 26mm to fit comfortably over a diving suit. Inside, the watch is powered by the Calibre 3135, a legendary "workhorse" automatic movement renowned for its durability and COSC-certified precision. The Rolex Deepsea 116660 is not just a timepiece; it is a pressurized fortress for the wrist, representing the absolute pinnacle of Rolex’s diving mastery.
