Rolex Sea-Dweller Deepsea – Reference 116660 (2012)

Heritage Narrative

When Rolex introduced the Sea-Dweller Deepsea ref. 116660 in 2008, it set a new standard in commercial dive-watch engineering. The 44 mm Oystersteel case features the patented Ringlock System—a unique construction of a nitrogen-alloyed steel compression ring, a 5.5 mm-thick domed sapphire crystal, and an RLX-titanium case back—enabling the watch to withstand water pressures down to 3,900 m / 12,800 ft. Powered by the chronometer-certified Calibre 3135, a movement praised for its reliability and 48-hour power reserve, the Deepsea balances technical prowess with everyday wearability. A unidirectional Cerachrom bezel, Chromalight luminescence, and a Glidelock clasp with a 20 mm tool-free extension complete the package, appealing equally to saturation divers and desk divers alike.
