The “Rolex Batgirl” is often used to describe a variant of the Rolex GMT-Master II with a black and blue ceramic bezel and a Jubilee bracelet.
This particular GMT has gained popularity within the watch community as a way to distinguish this particular GMT-Master II from the “Batman” reference, which has a similar black and blue bezel but is paired with an Oyster bracelet instead. For many this GMT is categorised as the most playfull Rolex watch.
The ROLEX BATGIRL typically refers to the following reference:
Rolex GMT-Master II Reference 126710BLNR: This model features a black and blue ceramic bezel, a stainless steel case, and a Jubilee bracelet. It was introduced in 2019 and is an updated version of the “Batman” reference. The new Jubilee bracelet that replaced the Oyster from the previous version has led to its association with the nickname “Batgirl.” It is not considered as a collectable watch but has gained an extreme popularity between the sport range of Rolex watches.

Vallée de Joux, Switzerland — Contributing Editor, high complications & independent watchmaking
Julien Favre learned the difference between good silence and bad silence before he was ten. Good silence was his grandfather at the bench in Le Sentier, loupe screwed into one eye, breathing shallow over a disassembled minute repeater. Bad silence was the moment a hairspring pinged off the peg-wood and disappeared into the floorboards. The family atelier — three generations of movement servicing for the maisons that carpet the Vallée de Joux — was never framed as a legacy Julien was expected to join. It simply was the house, the way weather is the house in a mountain valley.
He resisted it, predictably. He studied economics in Lausanne and spent two years in Geneva watch retail, selling the objects rather than opening them. What pulled him back was not sentiment but frustration: he found he could describe why a movement was beautiful far better than anyone selling it could, because he had seen its underside. He started writing — first a blog dissecting finishing under macro photography, then commissioned work for the trade press, then features that treated escapements the way music critics treat a fugue.
Julien now covers high complications, restoration, and the fragile economics of independent watchmaking for European and English-language titles. His reporting is unusually technical without being cold; he is as interested in the person hunched over the bench as in the tolerances they hold. He is skeptical of hype, allergic to press-release adjectives, and reliably the first to notice when a "revolutionary" caliber is a reworked ébauche.
He still returns to the family workshop each winter to service a single pocket watch on his grandfather's bench — a discipline, he says, that keeps his writing honest. A critic who cannot do the thing risks worshipping it. Byline version: Julien Favre is a contributing editor covering high complications and independent watchmaking. He grew up in a movement-servicing atelier in the Vallée de Joux and still works the family bench each winter
