Rolex Sea-Dweller 1665

Rolex Sea-Dweller reference 1665 housed in a robust 40mm stainless steel case with a pronounced domed acrylic crystal and was rated for an impressive 2000 feet (610 meters) of water resistance, significantly exceeding the Submariner’s capabilities at the time. Powered by the automatic Caliber 1570, the watch features a date function at 3 o’clock (without a Cyclops lens) and operates at a frequency of 19,800 vph with a power reserve of around 48 hours. The case includes the signature helium escape valve and is paired with a classic bi-directional bezel with an aluminum insert. Its bold case profile, thick case back, and professional diving specifications have made it a legend among Rolex tool watches.
