Rolex GMT Master II Automatic Black 40mm "Batgirl"

Rolex GMT-Master II "Batgirl", Reference 126710BLNR Oystersteel on Jubilee Bracelet, 40mm

Presented here on the elegant five-link Jubilee bracelet, the configuration that earned this watch its own nickname.

The blue and black bezel already had a name: Batman. But when Rolex introduced the 126710BLNR on the softer, more refined Jubilee bracelet, collectors decided it deserved one of its own. The Batgirl was born, and the distinction stuck permanently. Same iconic Cerachrom ceramic bezel, same black lacquered dial and blue GMT hand, but dressed with the polished five-link bracelet first created for the Datejust debut in 1945, giving the watch a noticeably more sophisticated, wrist-friendly character.

Inside runs the Calibre 3285 with a 70-hour power reserve, Chronergy escapement, and Superlative Chronometer certification to plus or minus two seconds per day. The Easylink extension system allows five millimetres of on-the-fly bracelet adjustment without tools.

For those who want the blue and black bezel combination with a dressier edge, the Batgirl on Jubilee remains the definitive choice. Two time zones, one of the most wearable bracelets Rolex makes, and a nickname that has entered the permanent vocabulary of watch collecting.
