Rolex GMT-Master II 40 mm 16710LN3 Steel Black Rolex GMT-Master II 40 mm 16710LN3 Steel…

The Rolex GMT-Master II ref. 16710LN3 for sale at Bizak & Co. is one of the most recognizable dual-timezone sport watches ever produced, and this particular example — finished in all-black with a steel case measuring 40mm across — represents the model at its most focused and purposeful. The GMT-Master family traces its origins to a collaboration with Pan American World Airways in the 1950s, designed so that pilots and crew could read a second time zone at a glance. The GMT-Master II refined the concept by allowing the local hour hand to be set independently of the GMT hand, a feature that transformed it from a cockpit tool into the globetrotter's watch of choice worldwide.

The 16710 reference occupies a beloved chapter in the GMT-Master II story, representing the generation that carried the aluminum bezel tradition forward before the line eventually transitioned to ceramic. The all-black aluminum bezel insert on this 16710LN3 configuration gives the watch a stealthy, cohesive appearance that pairs seamlessly with the black dial. The result is a dial side that reads with exceptional clarity under any lighting condition, the gilt or luminous hour markers and hands cutting cleanly against the dark background.

Constructed entirely in Oystersteel, the 40mm Oyster case is classic GMT-Master II architecture — broad lugs, a screw-down crown protected by its signature crown guards, and a screwed case back that contributes to the watch's 100-meter (330-foot) water resistance. The Oyster bracelet completes the package with Rolex's characteristic solidity, its center and outer links flowing naturally from the case and terminating in a deployant clasp. On the wrist the 40mm diameter wears with the confident, sport-watch presence that has made this model a mainstay of both professional and casual wardrobes for decades.

Power comes from a Rolex automatic movement, giving the wearer the convenience of self-winding operation through normal wrist motion. The GMT-Master II's hallmark complication — the independently adjustable local hour hand working in concert with the 24-hour GMT hand referenced against the graduated bezel — means crossing time zones is handled with a single crown adjustment rather than a full time-set. It is a practical, intuitive system that rewards frequent travelers and anyone who regularly communicates across time zones.

Buying a used Rolex GMT-Master II 16710LN3 from Bizak & Co. means acquiring a certified authentic example backed by the expertise of a dedicated luxury watch specialist. The all-black bezel variant consistently commands strong enthusiasm among collectors, and the 16710 generation is widely regarded as a transitional grail piece — desirable for its aluminum bezel character before the ceramic era, yet fully capable as an everyday sports watch.
