The early Sea-Dweller models, including the present watch, could withstand pressure up to impressive depths of 2000 feet or 610 meters, making them the world’s most robust water-resistant watches at the time. The Sea-Dweller model amply embodies complex horological technology and sophisticated craftsmanship that enable Rolex to be an industry leader for decades.
The red wordings of this dial, “Sea-Dweller, Submariner 2000” is dubbed by watch enthusiasts as “Double Red”. The present watch is fitted with a Mark IV dial, of which the “Double Red” letterings are vivid and clear, while the font of the red lettering is notably larger on the top line. The Rolex coronet is large, with clearly-defined spikes and a more pronounced “O” under the coronet.
Manufactured in 1977, the present watch is likely one of the very last examples of reference 1665 manufactured by Rolex that has the signature “Double Red” lettering.
