This is a beautiful example of a Rolex Sea-Dweller, Ref. 1665, from 1981. The original Mark IV dial on this watch is in excellent condition with pleasing lume markers and matching hands. The case on this piece is strong with the normal surface wear. The watch comes on a heavy Rolex oyster flip-lock bracelet with diver’s extension.

1967 saw the launch of the Oyster Perpetual Sea-Dweller, waterproof to a depth of 610 metres. To meet the needs of professional deep-sea divers, the case was equipped with a helium escape valve so that, during long decompression phases in hyperbaric chambers, the helium from the gas mixtures used could be released without risking damage to the watch.
