Rolex GMT Master II 40 mm 116759SANR White Gold/Diamonds Black

The Rolex GMT-Master II is one of the most storied tool-watch lineages in horological history, originally developed in collaboration with Pan American World Airways in the 1950s to allow pilots and navigators to track two time zones simultaneously. Over the decades it evolved from a professional aviation instrument into a broadly coveted icon worn by world leaders, executives, and collectors alike. Reference 116759SANR represents the apex expression of that evolution — a GMT-Master II transformed into a genuine jewel watch without sacrificing any of its functional DNA.

At 40mm, the 116759SANR wears with the authoritative yet wearable proportions that have defined the GMT-Master II case for generations. The case and integrated Oyster bracelet are rendered entirely in 18k white gold, lending the watch a cool, luminous presence on the wrist that sets it apart from the far more common steel and two-tone variants. The white gold construction elevates the tactile experience as well — the heft and temperature of the metal are immediately perceptible and deeply satisfying.

The bezel is where 116759SANR truly distinguishes itself: in place of the ceramic or aluminum insert found on standard references, the two-tone 24-hour graduated bezel here is pavé-set with diamonds and colored gemstones, creating a breathtaking play of light while retaining the bidirectional-reading GMT scale. Beneath it sits a rich black dial — one of the most classically elegant dial choices in the GMT-Master II catalogue — whose depth and contrast allow the applied hour markers and hands to remain highly legible despite the watch's extravagant jeweled frame.

Powering the watch is Rolex's automatic movement, a self-winding caliber with a quick-set independent GMT hand that allows the wearer to set a second time zone or home time without disrupting the running of the local-time hours hand — a genuinely practical complication for frequent travelers. The movement is housed within the Oyster case, which Rolex rates to 100 meters (330 feet) of water resistance, providing meaningful protection for a watch of this value and everyday wearability unusual for a gem-set piece.

For collectors, 116759SANR occupies a rare intersection: it is a fully functional, in-production-era GMT-Master II with the sport-watch pedigree that commands a passionate global following, yet finished to a standard typically associated with dedicated high-jewelry complications. Production numbers for this reference were always extremely limited, and finding a certified authentic example in pre-owned condition represents a genuine acquisition opportunity.
