Key features of the 1983 Sea-Dweller ref 1665 include a robust stainless steel case, which measures 40mm in diameter and is designed to withstand depths of up to 610 meters (2000 feet). The black dial, with its highly legible white hour markers and hands, is both functional and timeless in design. The model retains the iconic date function at the 3 o’clock position, but unlike the Submariner, it does not have a Cyclops lens over the date to maintain structural integrity at great depths. Powered by the reliable Caliber 1570 automatic movement, the Sea-Dweller 1665 offers proven precision and durability. The combination of its impressive technical specifications, historical significance, and distinctive aesthetic makes the 1983 Sea-Dweller 1665 a highly sought-after piece among collectors and diving enthusiasts alike. |
