Debuting in 1967, with the specific aim of bolstering Rolex's dive watch offering, the Rolex Sea-Dweller built upon the industry-leading dive watch credentials that the Submariner had earned Rolex over the previous 14 years. Created specifically with professional divers in mind, Rolex collaborated with diving companies like COMEX to perfect the Sea-Dweller's design and ensure it would be the ultimate dive watch. Featuring the ingenious Helium-Escape Valve that Rolex had patented the same year, a hugely impressive water resistance, and a sizeable case design, the Sea-Dweller rightfully toppled the Submariner as Rolex's most hardcore dive watch. Today offered in a few separate styles such as two-tone, with various dials, and in two different case sizes (43mm and 44mm), the Sea-Dweller has taken a leaf from the rest of Rolex's offerings and merged its tool-watch focused design with tasteful aesthetics, to create one of the most sought-after and best-equipped dive watches that any diver might ever need.

Watch is in excellent overall condition. There are small marks and scratches visible on the case sides and along some of the bracelet. Dial and ceramic bezel insert appear to be near-mint without any marks. Bracelet has12 full, 2 half links - 4 full links removable. 1 extra full link and 1 divers extension on the side.

An icon within Rolex's dive watch category, the Sea-Dweller has earned its title as one of Rolex's most robust offerings with its impressive water resisitance and hefty construction.
