Description
The Rolex Sea-Dweller, reference 16660—affectionately known among collectors as the **”Triple Six”**—is one of the most historically significant neo-vintage Rolex dive watches ever produced. Introduced in the late 1970s, the 16660 marked a major evolution of the Sea-Dweller line, becoming the first model to feature a scratch-resistant sapphire crystal and a significantly increased water resistance of 1,220 metres (4,000 feet). Produced for a relatively short period, the Triple Six bridges the gap between vintage charm and modern Rolex engineering, making it one of the most desirable references for serious collectors.
The robust 40mm Oystersteel case is paired with a classic black dial featuring luminous hour markers and Mercedes hands, delivering exceptional legibility both above and below the surface. A black unidirectional bezel with a 60-minute dive scale reinforces its professional diving credentials, while the helium escape valve—developed in partnership with professional saturation divers—allows the watch to withstand the extreme pressures encountered during deep-sea expeditions. Its balanced proportions and timeless design have cemented the 16660 as a true icon within the Rolex Professional collection.
Powering the watch is the renowned Rolex Calibre 3135 automatic movement, one of the most respected and reliable mechanical movements ever produced. Officially certified as a COSC chronometer, the movement operates at 28,800 vibrations per hour and offers approximately **48 hours of power reserve**. Featuring Rolex’s free-sprung balance and Parachrom technology in later service iterations, the Calibre 3135 has earned a reputation for exceptional precision, durability, and ease of servicing, making it a benchmark in Swiss watchmaking.
Presented as a **complete set**, this Rolex Sea-Dweller 16660 represents an increasingly rare opportunity to acquire one of Rolex’s most collectible neo-vintage sports watches. Revered for its historical significance, robust engineering, and enduring investment appeal, the “Triple Six” remains a cornerstone reference for collectors seeking an authentic piece of Rolex diving history with all the character of a true neo-vintage icon.
