Rolex GMT Master-II 40 mm 116713LN1 Steel/Yellow Gold Black

The Rolex GMT-Master II is one of the most storied tool watches in horological history, originally developed in partnership with Pan American World Airways in the 1950s to allow flight crews to read two time zones simultaneously. Over subsequent decades Rolex evolved the GMT-Master into the GMT-Master II, adding an independently adjustable 24-hour hand so the wearer can track a third time zone, and the reference 116713LN1 represents a mature, fully resolved expression of that lineage in the brand's signature two-tone Rolesor configuration.

The case of the 116713LN1 measures 40mm in diameter and is crafted from a combination of Oystersteel – Rolex's proprietary 904L stainless steel alloy chosen for its exceptional corrosion resistance and high polish retention – and solid 18k yellow gold deployed on the bezel, crown, and Oyster bracelet center links. This Rolesor treatment gives the watch a warm, immediately recognizable aesthetic that reads as both professional and luxurious on the wrist, complementing a wide range of dress codes from business travel to weekend wear.

The black dial is clean and authoritative, framed by the watch's signature bidirectional rotating bezel fitted with a black Cerachrom ceramic insert. Rolex's Cerachrom material is virtually scratch-proof, colorfast against UV exposure, and chemically inert, meaning the bezel retains its deep jet-black appearance indefinitely – a meaningful improvement over the aluminum bezels found on earlier GMT references. The combination of the black bezel and black dial gives the 116713LN1 a cohesive, stealthy character that has made the all-black bezel GMT one of the most sought-after configurations in the lineup.

Power comes from a Rolex-manufactured automatic movement, providing the smooth sweep second hand and self-winding convenience expected of a modern Rolex sports reference. The GMT-Master II's movement allows the 24-hour hand to be set independently of the local-time hour hand, enabling true three-timezone reading – a practical feature that resonates as strongly with frequent international travelers today as it did when the model was first conceived for professional aviators.
