Rolex Sea-Dweller Deepsea 44 – Black Dial – Oyster Bracelet (Ref. 126660)

Engineered to conquer the deepest oceans, the Rolex Sea-Dweller Deepsea 44 – Black Dial – Oyster Bracelet (Ref. 126660) is the ultimate expression of Rolex’s dive watch mastery. Designed for professional saturation divers and adventurers alike, this timepiece pushes the boundaries of underwater durability and technical performance.

Crafted from robust Oystersteel, the 44mm case houses a patented helium escape valve and a unidirectional rotating bezel fitted with a Cerachrom ceramic insert. The platinum-coated 60-minute graduations allow divers to monitor their descent with precision. The 5.5mm-thick domed sapphire crystal ensures strength and clarity under immense pressure.

Beneath the surface lies the Rolex Calibre 3235 — a self-winding mechanical movement delivering exceptional chronometric precision and a 70-hour power reserve. The iconic black dial features Chromalight lume for extended low-light visibility, maintaining legibility in the harshest conditions.

Equipped with an Oyster bracelet featuring the folding Oysterlock safety clasp, Glidelock extension system, and Fliplock link, this model offers unmatched adjustability and security — even over a diving suit. Waterproof to an astonishing depth of 3,900 meters (12,800 feet), the Sea-Dweller Deepsea 126660 is not just a tool watch — it’s a feat of engineering.
