One of the most popular Rolex Oyster professional sports watches of the past few years is the reference 116710BLNR GMT-Master II “Batman” – known for its distinctive blue and black “Cerachrom” ceramic bezel. This was the first Rolex steel watch to include a two-tone ceramic bezel, and since then, in 2014, it has added a blue and red “Pepsi” Cerachrom bezel as Rolex updated the overall GMT-Master II collection with various new features, including a new movement.

While the Rolex Reference 126710BLRO (red and blue bezel) GMT-Master II stole a lot of attention last year (aBlogtoWatch hands-on here), this 126710BLNR (blue and black bezel) joins it, and is essentially an updated version of the Rolex Batman.
Remember the case is water resistant to 100 meters and (of course) the sapphire crystal and the Cyclops magnifying glass window above the date window. Now let’s discuss the movement. We’ve already discussed the movement when we introduced the GMT-Master II 126710 back in 2019, but I’ll provide you with the basic details again. The movement inside the latest generation GMT-Master is the in-house 3285 automatic movement, which is the GMT version of the Rolex 32XX generation movement. This automatic movement operates at 4Hz and now has a 70-hour power reserve. It also includes Rolex’s “Superlative Chronometer” rating, which is an overlay of a third-party COSC chronometer rating and Rolex’s more rigorous internal performance tests. What I really appreciate about the Rolex “Superlative Chronometer” rating is that (unlike most other watchmakers) it comes with specific performance commitments, one of which is a daily accuracy of plus or minus two seconds.

The new 126710 generation Rolex GMT-Master II is an upgrade over the previous 116710 in a number of respects. One feature, which is not an upgrade per se, but merely a cosmetic difference, is the choice of a matching steel bracelet. For many,fake rolex this will be the biggest difference between the Rolex Batman and the “Batgirl” (a nickname I don’t think is particularly appropriate). The previous generation BLNR (the code Rolex uses to refer to the lap style) was paired with a three-link Rolex Oyster bracelet (the middle link is polished), while the new generation BLNR is paired with an all-steel Jubilee bracelet.

Watch enthusiasts sometimes argue over which bracelet is better and which is more desirable, and in my opinion, they both have their merits. Some say the Jubilee bracelet feels a little too “old”, but that’s only Rolex GMT-Master II 126710BLNR Black Bezel Watches because Rolex hasn’t used the bracelet for its sports watches lately, so it’s mostly associated with the more vintage Rolex timepieces.The Jubilee style bracelet is very comfortable, and it uses the same unfolding clasp (with “comfort extensions”) as the three-link bracelet. To me, these are just two different flavors of bracelets, but they both match the GMT-Master II.
