Launched in 1967, the Sea-Dweller reference 1665, was the first wristwatch designed for use in saturation diving. Aimed for amateur and hobbyist divers, ref. 1665 was modeled after the Submariner, with a tougher case and pressure-release valve allowing the watch to withstand compression.
The present ref. 1665 is an original example of a Mark II dial variation of the Double Red Sea-Dweller. Distinguished by two lines of red type applied directly to the dial, "SEA-DWELLER" is written in a larger type than "SUBMARINER 2000." Further, the Rolex coronet is highly distinctive on Mark II dials as it appears smaller, with a diminutive "o" base.
The present example has been serviced by Rolex, indicated by the strike-through case back inscription noting the proper case number "662," a frequent occurrence among reference 1665 models. With a beautiful and uniform chocolate brown dial among it's other unique features, this watch an attractive collector's piece.
