2019 Rolex Sea-Dweller SD43 Ref 126600

About The Watch:

The Rolex Sea-Dweller Ref 126600 was introduced in 2017, as a celebration of the 50th Anniversary of the first Sea-Dweller. The SD43, as it is known, debuted the new 43mm case size and 22mm lug width. The Ref 126600 also introduced the single Sea-Dweller text line in red on the dial, as well as a cyclops magnifier over the date window.

The History:

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 the cases of diving watches, during extended periods at depth, which would then escape through the weakest parts of a watch during decompression. Many times, it would escape by popping the plexiglass 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.

The Watch:

The Sea-Dweller Ref 126600 has a stainless steel 43 mm case, with a sapphire crystal. The bezel is unidirectional rotating with a 60-minute graduated, scratch-resistant Cerachrom insert in ceramic, which has numerals and graduations coated in platinum. Powered by the Calibre 3235 movement, the SD43 has a 70-hour power reserve and a water resistance rating of 4000 feet. The stainless steel Oyster bracelet has the folding Oysterlock safety clasp with a Rolex Glidelock extension system and the Fliplock extension link.

This 2019 Rolex Sea-Dweller is in good condition. The case has some wear marks, with some slight nicks on the sides of the case that are visible in the photos.
