Rolex · Family: GMT-Master II
The Rolex GMT-Master II "Batman" (ref. 126710BLNR) is the current-production 40mm GMT tool watch wearing Rolex's two-tone black-and-blue Cerachrom ceramic bezel, updated in 2019 to house the in-house Calibre 3285. Cazador has zero verified price observations, so no market range can be published. Its differential: an independently adjustable 24-hour GMT hand paired with a Chronergy-escapement movement rated at approximately 70 hours of power reserve.

3 of 5 price observations needed to show a reliable range
Insufficient data: 3 observations recorded as of today. Cazador does not estimate a range without sourced data — this block activates once at least 5 verified PricePoints exist.
The Rolex GMT-Master II 126710BLNR, nicknamed the "Batman," pairs Rolex's dual-time GMT complication with a two-tone black-and-blue Cerachrom ceramic bezel insert. This exact configuration, combining the two-tone bezel with the in-house Calibre 3285, entered Rolex's catalog in 2019 and remains in active production today.
At the core of the 126710BLNR is the Calibre 3285, a Rolex manufacture movement built around the Chronergy escapement, engineered for improved energy efficiency and greater resistance to shocks and magnetic interference. The movement delivers approximately 70 hours of power reserve and carries Rolex's Superlative Chronometer certification.
The GMT function is built around an independently adjustable 24-hour hand: the wearer can jump the local-time hour hand forward or back via the crown without stopping the seconds or disturbing the separate 24-hour GMT hand, which tracks a second time zone against the bidirectional, 24-hour graduated bezel.
The case is finished in Oystersteel at 40mm and rated to 100 meters of water resistance — modest next to the Submariner's dive-rated depth, appropriate for a travel watch. The black dial sits beneath a sapphire crystal fitted with the Cyclops lens over the date window. The bracelet is the three-link Oyster, closed with the Oysterlock clasp.
As of this writing, the 126710BLNR remains part of Rolex's current catalog and in active production, with no discontinuation announced.
Cazador has zero verified PricePoint observations for the 126710BLNR, so we cannot publish a reliable secondary-market range yet.
The nickname comes from its two-tone black-and-blue Cerachrom ceramic bezel insert, a color pairing collectors associate with the superhero — an informal, community-given name.
It runs Rolex's in-house Calibre 3285, an automatic movement with the Chronergy escapement, roughly 70 hours of power reserve, and Superlative Chronometer certification.
Yes. Per manufacturer catalog data, the 126710BLNR remains a current-catalog reference in active production, with no discontinuation announced.
The case measures 40mm in diameter, cased in Oystersteel, with a bidirectional 24-hour graduated bezel carrying the two-tone Cerachrom insert.
The 24-hour GMT hand is independently adjustable via the crown, letting the wearer set a second time zone against the bezel's 24-hour scale.
It's rated to 100 meters, sufficient for swimming and everyday water exposure but not a depth rating built for dedicated scuba diving.
