Sea-Dweller Deepsea, 126660, Oystersteel, 2021

Product Description

Launched in 2014, the Sea-Dweller Deepsea stands as Rolex’s most substantial dive watch (Challenge aside). This 2021 reference 126660 measures 44mm across and 17mm thick, with a titanium case back and even a 5mm thick crystal, so there’s no getting around it, this is a watch with real presence, best suited to a more generously proportioned wrist.

But it’s not just about size. The real standout here is the dial, fading from deep blue into black with a gradient that genuinely catches the light. It’s a look that draws you in, but there’s serious capability behind it too. Crafted from Rolex’s corrosion resistant 904L steel and fitted with a helium escape valve, this is a watch built to handle the extremes, even if it spends most of its time closer to the surface.

Since its launch, enthusiasts have gravitated towards this model, earning it the nickname “James Cameron” in tribute to the director’s historic Mariana Trench dive, a fitting link for a watch built with deep sea exploration in its DNA.

Our 2021 reference 126660 is presented in excellent condition, showing only light signs of wear and no signs of polishing. It comes as a full set, complete with its 2021 dated warranty card, booklets, one tag, and the large Rolex box.

We welcome viewings in our Knightsbridge showroom.
