Discontinued, coveted, and engineered for the extremes, the pre-owned Rolex Sea-Dweller 4000 116600 is the ultimate expression of Rolex’s professional dive heritage. Born from the collaboration between Rolex, COMEX, and the US Navy, the Sea-Dweller was the first watch to feature a helium escape valve, making it indispensable for saturation divers. The 116600 pays tribute to that legacy while introducing modern upgrades such as a Cerachrom scratch-resistant ceramic bezel, Chromalight luminescence for superior legibility, and a 40mm Oystersteel case built to endure the harshest underwater conditions.

Beneath its iconic black dial beats Rolex’s automatic movement, delivering unwavering accuracy and reliability. The Oyster bracelet with Glidelock clasp ensures a secure, custom fit whether worn over a wetsuit or with formal attire, while the 1,220m (4,000ft) depth rating reaffirms its tool-watch credentials.

This pre-owned Rolex Sea-Dweller 4000 is in good condition, showing minimal signs of wear, and has been fully inspected, authenticated, and comes with an authentication certificate. It includes its original box and papers, making it a strong investment piece with enduring resale value. As production of the 116600 ceased in 2017, examples in this condition are increasingly scarce, offering both the exclusivity and the craftsmanship that serious collectors seek.
