Rolex GMT-Master II Ref. 126710BLNR

The Rolex GMT-Master II Ref. 126710BLNR, affectionately known as the “Batgirl,” represents one of the most compelling modern evolutions of Rolex’s legendary dual-time sports watch. Introduced as part of the current-generation GMT lineup, this reference pairs a classic 40mm Oystersteel case with a striking black and blue Cerachrom bezel, creating a watch that balances unmistakable Rolex DNA with contemporary refinement. It is a piece equally suited to frequent travelers, collectors, and those seeking a versatile luxury sports watch with real pedigree.

The bidirectional Cerachrom bezel features a black upper half and blue lower half, engraved with a 24-hour scale and filled with platinum via Rolex’s PVD process for lasting contrast and durability. This bezel works seamlessly with the independently adjustable GMT hand, allowing a second time zone to be tracked at a glance—while the local hour hand can be set independently without stopping the movement. The glossy black dial provides a clean, highly legible backdrop for the applied white-gold hour markers and Mercedes hands, all filled with Chromalight lume that emits a long-lasting blue glow in low-light conditions.

Powering the 126710BLNR is Rolex’s in-house Calibre 3285, a cutting-edge automatic movement featuring the Chronergy escapement, Parachrom hairspring, and a robust 70-hour power reserve. This movement delivers exceptional efficiency, shock resistance, and precision, and is regulated to Rolex’s Superlative Chronometer standard of −2/+2 seconds per day. The smooth functionality of the GMT complication and quick-set local hour hand make it one of the most user-friendly travel watches on the market today.

A defining feature of the “Batgirl” is its Jubilee bracelet, which adds a refined elegance not found on its Oyster-bracelet sibling. Crafted from Oystersteel with polished center links and brushed outers, the bracelet offers both comfort and visual sophistication. It is secured by Rolex’s Oysterlock safety clasp and includes the Easylink extension system, allowing for quick micro-adjustments to accommodate changes in wrist size throughout the day.

As a modern icon within the GMT-Master lineage, the Rolex GMT-Master II Ref. 126710BLNR stands out for its perfect fusion of heritage, innovation, and everyday wearability. It delivers the tool-watch functionality that made the GMT-Master famous, while its ceramic bezel, upgraded movement, and Jubilee bracelet elevate it firmly into contemporary luxury territory. For collectors and enthusiasts alike, the “Batgirl” remains one of the most desirable and well-rounded Rolex sports models of the modern era.
