Rolex Oyster Perpetual GMT-Master II Ref. 116710BLNR
The Oyster Perpetual GMT-Master II has long been one of Rolex’s most recommended entry-level professional models. Launched at Baselworld 2013, the Ref. 116710BLNR stands out with its distinctive two-tone Cerachrom bezel — blue representing daytime hours from 6 a.m. to 6 p.m., and black representing the nighttime hours.
The 40 mm Oyster case is guaranteed waterproof to a depth of 100 meters. Its middle case is crafted from a solid block of 904L stainless steel, offering exceptional resistance to corrosion. The sapphire crystal is fitted with the signature Cyclops lens at 3 o’clock for easy reading of the date.
The black lacquer dial features 18 ct white gold hour markers, while both the hands and indices are coated with Chromalight, ensuring long-lasting blue luminescence in the dark.
Inside beats the Rolex Caliber 3186 self-winding mechanical movement, entirely developed and manufactured by Rolex. It is fitted with a blue Parachrom hairspring, offering superior resistance to shocks and magnetic fields. The movement provides a power reserve of approximately 48 hours and is certified as a Swiss chronometer by COSC.
With its timeless design, robust build, and practical dual time-zone functionality, the GMT-Master II “Batman” remains a classic choice for those who appreciate stainless steel sports watches that stand the test of time.
