Description
The Rolex GMT-Master II with reference 126710BLNR from 2020 is one of the most sought-after and modern versions of the legendary Geneva pilot’s watch. Affectionately known by the watch community as the “Batgirl” - a nickname inspired by the combination of the two-tone blue and Black Cerachrom ceramic bezel with the elegant five-link Jubilee bracelet - this model combines functionality for worldwide travel with refined sportiness. Equipped with the highly advanced Calibre 3285, it sets the gold standard for modern time-zone Chronometers.
Finely balanced 40 mm Oystersteel case: Crafted from high-strength, corrosion-resistant 904L stainless Steel (Oystersteel), the case architecture impresses with its satin finish, mirror-polished flanks and characteristic Triplock crown guard.
Two-tone Blue and Black Cerachrom bezel: The bidirectionally rotatable 24-hour bezel features a seamless ceramic insert, with Blue symbolizing daytime hours and Black symbolizing nighttime hours. The engraved numerals and graduations are filled with a fine layer of platinum using the PVD process.
Deep Black dial with Blue GMT hand: The high-contrast dial offers excellent legibility. The Blue GMT hand with its distinctive arrow tip indicates the second time zone. The 18-karat White Gold hour markers and hands are coated with intensely Blue-luminescent Chromalight material.
In-house Manufacture Calibre 3285: The latest-generation high-performance movement beats inside, featuring the patented Chronergy escapement, an antimagnetic Blue Parachrom hairspring and the Paraflex shock protection system. It offers an increased power reserve of approximately 70 hours with guaranteed Chronometer precision (-2/+2 seconds per day).
Anti-reflective Sapphire Crystal with Cyclops lens: A flat, internally anti-reflective Sapphire Crystal provides lasting protection for the dial. The magnifying lens at 3 o’clock enlarges the date window two and a half times.
Iconic water resistance (100m / 10 ATM): The screw-down Triplock winding crown with a triple sealing system and the hermetically screw-down case back reliably protect the movement against water, dust and pressure.
Five-link Jubilee bracelet in Oystersteel: The “Batgirl” is worn on a supple Jubilee bracelet with polished inner links and satin-finished outer links. It is equipped with an Oysterlock safety folding clasp and the practical Easylink extension system (+5 mm).
