The Rolex Deepsea reference 126660 represents a significant evolution of the brand's professional dive watch line, positioned above the Submariner and Sea-Dweller in terms of water resistance and case dimensions. Introduced in 2018, this reference updated the previous 116660 with a new movement and subtle case refinements, maintaining its robust character designed for extreme underwater exploration. It is notable for its Ringlock System case architecture, which allows for its exceptional pressure resistance.

This reference features a 44mm Oystersteel case with a substantial thickness of 17.7mm, housing the automatic caliber 3235, which provides a power reserve of approximately 70 hours. The watch is fitted with a domed sapphire crystal and is water-resistant to 3900 meters (12800 feet), a testament to its engineering for deep-sea environments. A unidirectional rotating bezel with a black ceramic insert facilitates dive timing.

Collector interest in the 126660 often centers on its technical capabilities and its imposing wrist presence. It appeals to those who value a highly engineered tool watch with a focus on extreme water resistance. The reference is available with either a classic black dial or the distinctive D-Blue gradient dial, the latter being particularly sought after for its unique aesthetic and association with deep-sea exploration.

The Rolex Deepsea Sea-Dweller ref. 136660 is positioned as a professional saturation diving instrument within the Oyster Perpetual collection, designed for extreme underwater exploration. It represents the pinnacle of Rolex's dive watch engineering, offering enhanced water resistance and a more substantial case profile compared to the standard Sea-Dweller models.

This reference features a 44mm Oyster case crafted from Oystersteel, equipped with a Ringlock System that allows it to withstand immense pressure. It houses the Caliber 3235, a self-winding mechanical movement entirely developed and manufactured by Rolex, featuring a Chronergy escapement and a power reserve of approximately 70 hours. The watch is distinguished by its D-blue dial, transitioning from brilliant blue to abyssal black, and a unidirectional rotatable bezel with a black Cerachrom insert.

For collectors, the ref. 136660, particularly with the D-blue dial, holds significance due to its association with James Cameron's Deepsea Challenger expedition. It is valued for its robust construction, advanced technical features, and its status as a highly capable and visually distinctive professional diver's watch.
