Rolex GMT-Master II 40 mm 116758SANR Yellow Gold/Diamonds Black Rolex GMT-Master II 40 mm 116758SANR Yellow…

The Rolex GMT-Master II is one of the most storied and recognized complication watches ever produced, originally developed in partnership with Pan American World Airways to give long-haul pilots and navigators the ability to read two time zones simultaneously. Over decades the line has grown from a practical aviation instrument into a benchmark of horological prestige, and reference 116758SANR represents the absolute pinnacle of that evolution — an 18k yellow gold interpretation dripping in diamonds and sapphires that transforms a working tool watch into a genuine collector's trophy.

At 40mm in diameter, the 116758SANR wears with the confident, balanced proportions that made the GMT-Master II a global icon. The case is sculpted from 18k yellow gold and paired with an Oyster bracelet that is itself set with diamonds, creating a unified tapestry of precious metal and gemstone from lug to lug. The warm glow of yellow gold against the deep black dial produces a contrast that is simultaneously dramatic and refined, a combination that photographs beautifully and commands attention in person.

The bezel is the reference's most immediately arresting detail: a full gem-set configuration featuring diamonds and sapphires in place of the traditional ceramic or steel insert. Rather than the familiar two-tone color coding of a standard GMT bezel, this version uses precious stones to delineate the 24-hour scale, each gem selected and set to exacting standards. It is a statement that Rolex makes very deliberately — that technical excellence and haute joaillerie can coexist without compromise.

Powering the watch is a Rolex automatic movement, the self-winding caliber at the heart of every GMT-Master II, providing the signature independently-adjustable GMT hand that allows the wearer to track a second time zone at a glance. Water resistance is rated to 100 meters / 330 feet, meaning the 116758SANR is not merely a safe display piece but a fully functional, wearable luxury instrument built to Rolex's exacting standards of robustness and precision despite its extraordinary jeweled exterior.

From a collector's standpoint, the 116758SANR occupies a rarefied position in the GMT-Master II catalog. Full yellow gold gem-set references are produced in limited numbers relative to steel or even white gold variants, and their combination of precious metal, fine stones, and mechanical complication ensures sustained desirability in the secondary market. Buyers who seek a Rolex that doubles as a fine jewelry piece without surrendering any of the brand's legendary durability will find no better candidate.
