The Rolex Deepsea model was introduced in 2008, boasting a depth rating of 3,900 meters due in part to its Ringlock System case architecture and Helium Escape Valve. In 2014, Rolex released a commemorative version of the Deepsea featuring a D-Blue gradient dial after James Cameron completed the Deepsea Challenge in 2012 with a Rolex experimental watch on his submersible. The D-Blue version is shown in the photo above on a Rubber B dual tone VulChromatic strap.
The Ringlock System is based on a case architecture that features a nitrogen-alloyed stainless steel ring inside the middle case between the case back and crystal, a domed 5.5 mm thick sapphire crystal and a grade 5 titanium case back. The middle case is made from a solid block of 904L stainless steal and the case features a Triplock winding crown for additional waterproofness.
This dive watch is also equipped with a Helium Escape Valve that allows the helium that penetrates the watch during deep water saturation to escape without damaging the timepiece when the gas expands during decompression. The words ‘Helium Escape Valve’ and ‘Ring Lock System’ are etched onto the case at the 12 o’clock and 6 o’clock positions.
The watch features a 60-minute graduated unidirectional Cerachrom bezel that allows divers to monitor their decompression time. Cerachrom is a proprietary ceramic material used by Rolex on their bezel inserts that makes them virtually scratch-proof. The bezel has a knurled edge that makes it easier for a diver to manipulate it with dive gloves on.
The Deepsea comes with an Oysterlock safety clasp fitted with Rolex’s Fliplock extension system that extends the oyster bracelet by 26 mm and their Glidelock extension system that extends it by an additional 20 mm. This allows one to wear the Deepsea over a thick wet suit that would be required for dives in cold water temperatures.
This Superlative Chronometer is fitted with a Calibre 3135 movement manufactured completely in-house by Rolex. It has a power reserve of up to 48 hours. The case measures 44 mm in diameter and is made of 904L stainless steel, another proprietary material of the watchmaker.
The suggested retail price for the Rolex D-Blue Deepsea is 11,800 Swiss francs. For more information on this or any other Rolex model, visit rolex.com.
