Rolex 116660 Deepsea Sea-Dweller SS Black Dial

The Rolex 116660 Deepsea Sea‑Dweller in stainless steel with a black dial stands as a landmark of professional dive watch engineering. Introduced in 2008, this reference was designed to push the boundaries of underwater performance, featuring Rolex’s patented Ringlock System and a grade‑5 titanium caseback to withstand depths of 3,900 m (12,800 ft). It houses the reliable, chronometer‑certified Caliber 3135 automatic movement, renowned for its robustness and approximately 48‑hour power reserve. The 44 mm Oystersteel case is paired with a unidirectional Cerachrom bezel and a thick 5.5 mm domed sapphire crystal, delivering both durability and legibility under extreme pressure. The watch includes a Glidelock clasp with Fliplock extension, enabling precise adjustment over diving suits. Its black dial, with Chromalight luminescence and date at 3 o’clock, maintains the tool‑watch aesthetic while offering modern functionality. The Deepsea’s combination of unmatched depth rating, advanced materials, and proven movement makes it highly prized among collectors and serious divers alike. Excellent Condition with Rolex box and papers dated 2017.
