The Rolex GMT-Master II 126710BLNR on the Jubilee bracelet — nicknamed the "Batgirl" — represents the more refined, dressy expression of the black/blue ceramic bezel GMT. While the "Batman" sits on the Oyster bracelet, the Batgirl's five-link Jubilee gives the reference a more elegant wrist presence beloved by collectors.
