Rolex Sea-Dweller Black Dial Steel Watch 126600

Rolex expanded the Sea-Dweller platform with the ref. 126600, increasing the case to 43mm and reinforcing its deep-sea capability to 1,220 meters. The helium escape valve remains integral to its function in pressurized diving systems. On the black dial, luminous plots and broad hands ensure legibility in low light conditions, while the red “Sea-Dweller” text restores the historic signature. A unidirectional Cerachrom bezel provides precise timing control. Caliber 3235 powers the watch with a 70-hour reserve and precise rate stability. Offered pre-owned, this Rolex Sea-Dweller Black Dial Steel Watch 126600 comes with papers and the manufacturer’s box.
