We are proud to present the impressive Rolex Sea-Dweller DeepSea MK I for sale.
The Sea-Dweller was originally developed in 1967 to compliment the already popular Submariner collection, the Sea-Dweller was developed originally for saturation divers working for SeaLab who were spending a lot longer underwater than your casual Submariner wearer. Because of those extreme conditions and depths, the divers noticed that the crystal would pop out of the case during decompression due to the helium particles in the case. So, Rolex developed the Helium release valve under their patent and thus the Sea-Dweller was born.
In 2008 Rolex launched the original version of the Deepsea, the ultimate evolution of the Sea-Dweller, flaunting a large 44mm Oyster case measuring a sizeable 17.7 mm thick. The size and thickness of the stainless steel case are required to achieve the Deepsea’s impressive water resistance of 3,900 meters. To attain this, the case is built according to Rolex’s patented Ringlock System, which includes a nitrogen-alloyed steel ring at the centre of the case, a helium escape valve to rid the watch of built-up gases, a 5.5 mm thick domed sapphire crystal, and a steel and titanium caseback.
This version is the original reference 116660 and is set in a 44mm stainless steel Oyster case with a uni-rotational black Cerachrom bezel. The dial is a clean black glossy finish with ‘Maxi’ style hour markers with Chromalight luminous filling and a date feature at 3 o’clock. Fitted with a domed sapphire crystal glass (5.5mm thick) and a Triplock screw-down crown for additional water resistance. It is powered by the Rolex calibre 3135 automatic movement with up to 48 hours of power reserve and comes fitted on the Oystersteel bracelet with a folding Oysterlock safety clasp with Glidelock extension system.
Originally purchased in August 2016 and in mint condition, this DEEPSEA comes with its original inner & outer boxes, seal, swing tag, leather card holder, instruction booklet, international warranty card and original receipt. It is being sold with a 12-month warranty from SWC.
