Description
The 2019 Rolex GMT-Master II with reference 126710BLNR is one of the most sought-after and modern versions of the legendary Geneva pilot’s watch. Affectionately dubbed the “Batgirl” by the watch community—thanks to the combination of its two-tone blue and Black Cerachrom ceramic bezel and elegant five-link Jubilee bracelet—this model combines functionality for worldwide travel with refined sportiness. Equipped with the 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 stands out with its satin finish, mirror-polished sides, and distinctive Triplock crown guard.
Two-tone blue and Black Cerachrom bezel: The bidirectional 24-hour bezel features a seamless ceramic insert, with blue symbolizing daytime and Black symbolizing nighttime. 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-shaped tip, indicates the second time zone. The 18-karat White Gold indices and hands are coated with intensely blue-glowing Chromalight material.
In-house Manufacture Calibre 3285: At its heart beats the latest-generation high-performance movement, featuring the patented Chronergy escapement, a paramagnetic blue Parachrom hairspring, and a Paraflex shock absorption system. It offers an extended power reserve of approximately 70 hours, with guaranteed chronometer precision (-2/+2 seconds per day).
Anti-reflective Sapphire Crystal with Cyclops lens: A flat Sapphire Crystal with anti-reflective coating on the inside 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 its triple-seal system and the hermetically sealed 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 center links and satin-finished outer links. It is fitted with an Oysterlock safety folding clasp and the practical Easylink extension system (+5 mm).
