The Rolex Sea-Dweller was designed with saturation divers in mind.  Due to the use of helium in the gas mixture during saturation dives, helium particles would accumulate in diving watches during extended periods at depth, which would then escape through the weakest parts of a watch during decompression.  It would often escape by popping the Plexiglas crystal off of the watch.  Rolex developed the helium escape valve, built into the side of the watch case, to combat this issue and, therefore, allow for a safe release of the gas and continued reliability and durability of the watch.

More About The Rolex Sea-Dweller Ref 16600

The History

The Rolex brand needs no introduction.  Founded in 1905 by Hans Wilsdorf and his brother-in-law, Alfred Davis, these visionary men set out to do what had not been successfully and reliably done before.  Build a timepiece to be worn on the wrist that is highly reliable, functional, and durable, as well as stylish.  Wilsdorf’s dream was to create a watch that could accompany its owner through all facets of life and withstand any environment.  His innovative approach and high standards for quality reshaped the watch industry as a whole.  It has made the Rolex name synonymous with quality, innovation, and elegance.  

The Watch

The Sea-Dweller Ref 16600 has a 40mm stainless steel case and a sapphire crystal.  The Ref 16600 utilizes the Calibre 3135 movement and has a water resistance rating of 4000ft.  The gloss black dial has circle and rectangle hour plots with Super-Lumiova lume and white gold surrounds and features a date window at the 3 o'clock position.  The hour and minute Mercedes-style hands are lumed.

The Details

This Rolex Sea-Dweller Ref 16600 is a P-serial number and dates to the production year of 2000.  It appears to be in unpolished condition, with sharp original case lines and chamfers present.  The case and bracelet show some wear, including on the crystal near the 6 o'clock position, that are consistent with a timepiece of this age, which is visible in photographs.  This timepiece includes the original 93160A Oyster bracelet.
