The Rolex GMT-Master II Ref. 116758SARU is an ultra-rare and exceptionally bold statement piece that elevates the legendary pilot’s watch to the realm of high jewelry, representing one of the most coveted and extravagant creations in Rolex’s modern lineup . Housed in a commanding 40mm 18K yellow gold Oyster case with a matching three-link Oyster bracelet, this model features a diamond-set case and a truly spectacular bi-directional rotating bezel set with a dazzling arrangement of baguette-cut blue sapphires, red rubies, and diamonds, a gemstone combination that gives the reference its celebrated “SARU” moniker (Sapphire and Ruby) and pays tribute to the iconic blue and red “Pepsi” bezel of the original 1950s GMT-Master . The black lacquer dial is a study in refined contrast, featuring the signature date window with Cyclops magnification at 3 o’clock and the vibrant green 24-hour hand for tracking a second time zone . At its heart beats the legendary in-house automatic Caliber 3186, a COSC-certified chronometer movement renowned for its robustness and precision, offering a 48-hour power reserve and protected by a 100-meter water resistance . Introduced in 2006 alongside the 50th-anniversary GMT-Master II, this reference was produced in very limited numbers and was historically available only to Rolex’s most exclusive VIP clientele, making it a true collector’s grail for those who demand the pinnacle of horological prestige and dazzling wrist presence . Key specifications: 40mm 18K yellow gold case with diamond-set case; black dial; gem-set “SARU” bezel with sapphires, rubies, and diamonds; Rolex Caliber 3186 automatic movement; 48-hour power reserve; 18K yellow gold Oyster bracelet; 100m water resistance; sapphire crystal.
