One of many classic discontinued 40mm Rolex 16600 Sea Dweller we sold. This F serial 16600 features the titanium helium escape valve on the left side of the case, and an aluminum bezel insert (currently a ceramic bezel insert on the newer Rolex 116660 Deep Sea). The 3135 movement (same as the Submariner 16610 movement) sits enclosed inside the case, and does not feature the blue parachrom hairspring. This 16600 Sea Dweller features a correct pointed four bezel insert.
The sapphire crystal has no cyclops, a feature both to distinguish it from the Submariner and to allow the diving depth of 4000 feet. While the 16600 Sea Dweller is thicker than the 16610 Submariner, its dial is actually smaller than the 16610 Sub. This F serial 16600 Sea Dweller was SOLD and delivered to our client with original Rolex boxes, manuals, and warranty paper.
