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

The Rolex GMT-Master II 116759SANRDB is widely regarded as the most opulent interpretation of one of horology's most celebrated tool-watch lines. Born from the original GMT-Master created in partnership with Pan American World Airways in the 1950s, the GMT-Master II evolved over decades to offer an independently adjustable 24-hour hand and a bidirectional rotatable bezel, allowing travelers to track a second time zone at a glance. Reference 116759SANRDB takes that storied legacy and transforms it into a wearable jewel, casing the movement in 18k white gold and replacing the traditional two-tone ceramic or aluminum insert with a bezel pavé-set with a graduated rainbow of multicolor sapphires and diamonds.

The case measures 40mm in diameter, a proportion that the GMT-Master II wore for many years before the line moved to 40mm with the introduction of the 116710 family and its successors. At 40mm the watch occupies the sweet spot between commanding wrist presence and everyday wearability, and the Oyster case architecture — with its screw-down crown and solid-link Oyster bracelet — gives the reference a water resistance of 100 meters (330 feet), a reminder that beneath all the gemstones lies a genuinely robust sports watch mechanism.

The dial is finished in deep black, a choice that creates dramatic contrast with the brilliance of the white gold case and the vivid multicolor sapphire bezel. The black dial allows the luminous hour markers and hands to stand out with purpose, preserving the GMT-Master II's core function as a legible, practical timepiece even in the context of a haute-joaillerie creation. The 24-hour hand sweeps continuously above the dial, pointing to the white gold and gem-set bezel to display the wearer's reference time zone.

Power comes from Rolex's self-winding automatic movement, the same family of calibers that underpins the broader GMT-Master II line and is recognized for its precision, reliability, and manufacture-level finishing. The movement's column-wheel-controlled mechanism for the independent GMT hand has long set the standard for dual-time complications, allowing the local hour to be set forward or backward in one-hour increments without stopping the seconds, a feature pilots, executives, and frequent travelers prize above almost everything else in a travel watch.
