Introduced in 2008, the Deepsea ref. 116660 took the Sea-Dweller collection to another level, at the time representing Rolex’s latest efforts in over-engineering their famed dive watch design and showcasing their continued and lasting chops in the underwater world.

In sum, the Deepsea was “the Formula 1 of Rolex divers,” as one former HODINKEE writer described it, its large 44mm by 17.5mm case representing the forefront of dive watch capabilities. These credentials exemplified with the launch of the 2014 D-Blue edition alongside the standard black edition: a special edition which commemorated director and explorer James Cameron’s 2012 dive into the deepest part of the ocean – the Mariana Trench.

At its core, the ref. 116660 gained instant recognition for more than tripling its water resistance from 1,220 meters to an astonishing 3,990 meters. The advancement came as a result of some serious engineering marvels, with the watch notably including the five millimeter-thick sapphire crystal to support the underwater pressure assisted by a visible Ringlock system on the dial that keeps the watch’s thickness below 18mm. A unidirectional, Cerachrom bezel adds to the watch’s professional grade credentials, as does a subtle helium escape valve opposite the screw-down crown.

On the dial, a highly-legible dial produced in Rolex’s distinct diver configuration is showcased, complete with a three o’clock cyclops-magnified date window, hour markers and hands are filled with blue Chromalight lume material, and a dark dial contrasting to it all. Worth noting is the 116660, like most Sea-Dwellers, does not feature a Cyclops magnifier over the date.

Inside is Rolex caliber 3135, an automatic movement with a 48-hour power reserve, an incredibly reliable, chronometer-grade movement used extensively by the brand. The caliber is protected via a solid titanium case back that helps manage weight and ensures a water resistance to 3,900 meters (12,800 feet), with the entire watch secured to the wrist via a 904L steel Oyster bracelet with a matching Oysterlock safety clasp to prevent accidental opening.
