Blue and Black Cerachrom Bezel
The bidirectional 24-hour bezel features a two-colour ceramic insert with moulded numerals and graduations for clear and durable reading.





The Rolex GMT-Master II reference 126710BLNR is distinguished by its black dial and blue-and-black ceramic bezel, a colour combination known among collectors as the “Batman.”
The two-tone bezel separates daytime from nighttime hours when reading reference time. Its arrow-tipped 24-hour hand works with the bidirectional graduated bezel to display time in another part of the world.
The conventional hour hand indicates local time and can be moved forwards or backwards independently, allowing the wearer to adapt to a new time zone without stopping the movement or affecting the minutes and seconds.
This configuration is completed by a five-piece-link Jubilee bracelet, adding a refined and fluid profile to the professional Oystersteel case.
The bidirectional 24-hour bezel features a two-colour ceramic insert with moulded numerals and graduations for clear and durable reading.
The blue arrow-tipped hand displays reference time on the 24-hour bezel, while the conventional hour hand indicates local time and adjusts independently.
The self-winding mechanical movement powers the GMT function, instantaneous date display and approximately 70-hour power reserve.
The 40 mm Oystersteel case combines corrosion resistance with polished and satin-finished surfaces for a refined professional appearance.
Broad hands and applied hour markers use long-lasting blue luminescence for clear legibility in low-light conditions.
The five-piece-link Jubilee bracelet is completed by an Oysterlock safety clasp and an Easylink extension providing approximately 5 mm of additional adjustment.
