Rolex GMT-Master II Automatic Ceramic Bezel with Black Dial S/S-Sapphire Glass
This Rolex was introduced to the world in April 2013 at BaselWorld. The watch clearly features the unique blue & black two-tone bezel and the 2nd hour hand is blue. Some people in the watch forums have been calling in the Rolex GMT “Batman” replica due to the color combo. Except for the blue accents, this watch is the same as the black bezel’d 116710.
You may have noticed the retail for this version is $500 more than the black bezel version. The reason is due to the added complexity of the blue and black ceramic bezel. Prior to 2007, on the steel GMTs, the bezel inserts were aluminum, and adding different colors to aluminum was elementary compared to the techniques needed to make this blue/black cerachrom bezel a reality. Cerachrom is Rolex’s patented proprietary system for creating their own ceramic. When Rolex introduced their original cerachrom bezels in 2005, Rolex said making a two-tone cerachrom bezel would be impossible. Some people at Rolex must have accepted a challenge to do the impossible.
Rolex starts with a completely blue mono-block cerachrom bezel, and then while it is still porous, they add a special solution of chemical compounds. Then, during the sintering stage (sintering is a method for creating objects from powders), the ceramic takes on its final attributes. The numerals on this bezel are a thin layer of platinum and the cerachrom bezel is diamond-polished.
The guaranty card included with this model states it is a 116710B, however Rolex and just about everyone on the internet refers to it as the 116710BLNR.
