Rolex Submariner Date 40 Black DLC Coating

The Rolex Submariner Date 40 is the reference dive watch, and this is a genuine Submariner Date that has been given an aftermarket black DLC coating. It is important to be clear on that point: Rolex does not produce a black-coated Submariner, so the finish here has been applied by a third party after the watch left Rolex, over an authentic steel Submariner Date. The result is an all-black, matte look that is very different from the standard steel, with the coating adding scratch resistance to the case and bracelet.

Underneath the coating it is the watch it has always been: a 40mm Oyster case, a unidirectional rotating bezel with a graduated insert for timing dives, the Chromalight dial and hands for low-light legibility, the date at 3 o'clock, and a screw-down crown. It runs Rolex's self-winding, chronometer-certified movement on the Oyster bracelet, and the underlying case retains the Submariner's serious water resistance.

Because the coating is aftermarket, it sits outside Rolex's warranty and service terms, this is a customised piece rather than a factory one, which is part of what makes an all-black Submariner stand apart from the standard model. At Konesseur, every watch is authenticated and inspected in Dubai before listing. See more Rolex or the full watches range to compare.
