Anyone gearing up to dive in the oceans abyss can benefit from this new and improved Rolex unveiled at Baselworld 2018. Introducing the new slightly improved and refined “Rolex Oyster Perpetual Deepsea Sea-Dweller”.



Here at EiT we’re proud to announce we’re currently one of the few vendors in the USA that have the “Rolex Oyster Perpetual Deepsea Sea-Dweller” (Ref#: 126660) iN stock! This updated version has grown from a 40mm to a 44mm case in a refreshed design; plus a broader bracelet and resized Oysterlock folding safety clasp. While on the technical side Rolex has improved precision and increased the power reserve. It’s equipped with the Chronergy escapement patented by Rolex, which features a Parachrom hairspring made of an exclusive paramagnetic alloy that is 10 times more precise than a traditional hairspring.

The model we’ve received is the black dial version, instead of the “D-Blue” dial. This edition exhibits the distinctive face of a Rolex which consumers worldwide have grown accustomed too. It is further characterized and embellished by 18k white gold hour index markers, which provide a stronger shine and are more resistant to tarnish.

Originally this watch debuted back in 2014 with the special D-blue dial. Although its prototype was first conceived and worn by James Cameron as can be seen in the documentary for “Deepsea Challenge 3D”.

The timepiece he wore was never actually made available on the horology market. For the documentary James Cameron was given an experimental “Deepsea Challenge” watch that had an astonishing water-resistance that could reach up to 12,000 meters (39,370 feet).


But, currently we do have the standard issue “Rolex Sea-Dweller Deepsea D-Blue James Cameron” (Ref#: 116660) in stock at EiT. For more in-depth information on this timepiece visit our blog review here, while our current in-store listing can be seen here.

This new updated version for 2018 has had some minor changes applied to the case, an updated bracelet, but the main difference was swapping out the caliber 3135 mechanical movement for the caliber 3235. That same caliber was also cased inside the 50th anniversary “Rolex Sea-Dweller” (Ref#: 126600) with red writing and a cyclops lens, we also have in stock and listed here.

Focusing back on the new updated “Deepsea” its 44mm case is made of stainless-steel, or the “Oystersteel” as Rolex has designated. The case consists of a monobloc middle case, a steel screw-down case back and the Rolex Ringlock system case architecture with a helium escape valve for alleviating pressure during diving sessions.

Comes equipped with a screw-in crown that has the Rolex Triplock triple waterproofness system, while the aforementioned helium escape valve has been aligned with the 9 o’clock position. It’s topped by an extra thick 5.5mm domed sapphire crystal that assists with water-resistance on this watch reaching up to 3,900 meters (12,800 feet).

Mounted to the case is a unidirectional rotatable steel bezel with a 60-minute graduated Cerachrom black ceramic insert that allows divers to monitor their underwater and decompression time for safety purposes. This Rolex-patented insert is made of an extremely hard and corrosion-resistant ceramic, which is virtually scratchproof and its color is unaffected by ultraviolet rays.

While the numerals and featured graduations are molded in the ceramic and colored with platinum using a PVD (Physical Vapor Deposition) process. With divers in mind the bezel’s knurled edges offer an excellent grip when manipulating the bezel to set dive time, even while wearing gloves.

Time is exhibited on the iconic D-blue dial which is predominately colored blue, but gradually shifts to black as it reaches downwards towards the bottom half of the dial, as if it were descending to the oceans depths. But, for 2018 Rolex has also made an all black dial version available, which we currently have iN stock at EiT, check our listing by clicking this link!

Both versions come with round hour index markers, expect for the 6 o’clock position which has a rectangular index and the 12 o’clock position with an upside-down triangular marker; followed by smaller white printed minute index markers.

The “DEEPSEA” inscription on the lower half of the dial has been colored green (except on the all black dial version) which adds an extra color highlight in this darker area. The central hands and hour index markers have been given a luminescent filling, for an enhanced legibility. There is also a white date aperture at the 3 o’clock position.
