Rolex - Sea-Dweller – Black - Red Letters – 126600 – 2017

The Rolex Sea-Dweller reference 126600, commonly nicknamed the “Single Red” or “Red Sea-Dweller,” debuted in 2017 to commemorate the collection’s 50th anniversary. Its black dial features a single line of red “SEA-DWELLER” lettering, recalling the celebrated red-text Sea-Dwellers of the late 1960s.

This generation introduced a larger 43mm Oystersteel case and the Sea-Dweller’s first Cyclops date magnifier. Powered by the Rolex calibre 3235, it offers approximately 70 hours of power reserve. A helium escape valve, fully graduated ceramic bezel and 1,220-metre water resistance equip it for professional saturation diving.
