A must for any respected Rolex collection, this vintage Double Red Sea-Dweller is blessed with a perfect dial and beautiful warm patina to the hands & batons.

Developed alongside specialist French diving company COMEX as an industrial version of the Submariner, the Sea-Dweller ref. 1665 featured a Helium escape valve on the case side, and the iconic two lines of bold, brick red text on the dial. Characterised by distinctively grained printing, this 1977 Mark IV example was one of the final models with the coveted "DRSD" printing. In outstanding original (unpolished) condition with a lovely thick case, warm buttery Tritium lume, nicely aged bezel insert, and original 93150 heavy link Oyster Fliplock bracelet.
