Rolex gets funny when it mentions upgrades to its latest generation of replica watches. You would think they’d be louder when discussing new features, but the truth is that Rolex is careful not to make their older watches look less sought-after. “A Rolex is always a Rolex” according to… well, Rolex. I’m not saying it is enough for 116710 generation GMT-Master II owners to “upgrade,” but for those who are keen to wonder what fake rolex made different, then it is more than just a band and a movement for the newest generation GMT-Master II. 
Recall that the case is water resistant to 100 meters, with a sapphire crystal and a Cyclops magnifier window over the date window. Now let’s discuss the movement a bit. We already talked about the movement when introducing the GMT-Master II 126710 back in 2019, but I will give you the basic details again. The movement inside the latest-generation GMT-Master is the in-house-made caliber 3285 automatic, which is the GMT version of Rolex’s 32XX generation of movements. The automatic movement operates at 4Hz, now 70 hours of power reserve. It also includes Rolex’s “Superlative Chronometer” rating, which is a stack of both third-party COSC Chronometer rating and more stringent in-house performance testing by replica rolex. What I really appreciate about Rolex’s Superlative Chronometer rating is that (unlike most other watch makers) it comes with special performance promises, one being accuracy to within plus/minus two seconds a day.
All Rolex movements perform pretty well, so aside from the increased power-reserve rating, I have a feeling that most Rolex wearers will not notice too much difference in terms of the movement operation from the last GMT-Master II generation to this most current 126710 family. When traveling, the movement allows the wearer to adjust the hour hand independently, which helps make it simple to adjust the local time when moving into different time zones.
A fair question to ask is whether or not one should seek out this blue and black 126710BLNR or the red and blue 126710BLNO — as they both cost and do the same things. In some respect, it is a matter of style and taste. It is also crucial to mention that both watches are currently very challenging to purchase at retail. That sort of implies that, for most buyers, the one they purchase is the one that they find available.
The enduring advice is that consumers should not pay more than the retail price, because in recent years speculators have been known to buy available, popular timepieces quickly and then try to resell them immediately at a premium. Such behavior will only benefit these speculators and should be avoided by most consumers.
