Introduced in 1967, the Rolex Sea-Dweller was developed in collaboration with professional deep-sea divers to meet the demands of saturation diving. Building on the success of the Submariner, it featured increased water resistance and the introduction of the helium escape valve, allowing trapped gas to safely exit the case during decompression. Designed as a true professional tool watch, the Sea-Dweller has remained purpose-built throughout its evolution, favouring functionality and robustness over embellishment. Today, it stands as one of Rolex’s most technically significant and respected sports watches.

Whats on Offer

This Rolex Sea-Dweller reference 1665 is the highly coveted Double Red variant, instantly recognised by the two lines of red text on the dial and regarded as one of the most important Sea-Dwellers ever produced. Dating to circa 1973, the matte black dial is beautifully preserved, with a crisp date aperture and iconic Mercedes hands filled with rich, butter-yellow luminous material that has aged evenly across the oversized hour plots.

The stainless steel case and Oyster bracelet remain in superb condition, showing only light signs of wear consistent with age, while retaining strong lines and excellent overall definition. The bezel is well preserved with clear markings and a sharp serrated edge. Supplied with its original box and papers, this Double Red Sea-Dweller is powered by Rolex’s calibre 1570 automatic movement and is offered with a 12-month warranty — a truly exceptional example of a landmark Rolex professional model.
