Short answer
A fake Rolex GMT-Master II 116710BLNR is a watch built to look like Rolex's steel GMT-Master II sold from 2013 to 2019. The genuine reference has a 40 mm Oystersteel case, a blue and black Cerachrom ceramic bezel, caliber 3186, and 100 m water resistance. Replica versions copy the shape, the dial, and the bezel colors. They do not contain Rolex-made movements, cases, or bezel inserts. Trafficking in counterfeit watches is a federal crime in the United States.
What the 116710BLNR is
Rolex launched the 116710BLNR in 2013. It was the first GMT-Master II with a two-color ceramic bezel insert. The blue and black sections come from one piece of ceramic, not two halves joined together. The blue half tracks night hours. The black half tracks day hours. Rolex patented the single-piece two-color ceramic process.
Rolex retired the reference in 2019. The replacement is the 126710BLNR, which uses caliber 3285, a 70-hour power reserve, and an optional Jubilee bracelet.

What replica versions copy
Replica 116710BLNR watches copy the outline: the 40 mm case, the blue and black bezel, the blue 24-hour hand, and the blue GMT-MASTER II line on the dial. Bezel inserts on replica watches range from coated aluminum to printed ceramic. The blue section can shift toward purple under daylight.
Three areas separate a copy from the real watch. First, the bezel. Genuine Cerachrom numerals are coated with platinum through a PVD process and sit inside the ceramic. Second, the movement. Caliber 3186 has a free-sprung balance with Microstella regulating nuts and a blue Parachrom hairspring. Replica movements do not carry that assembly. Third, the case and bracelet. Oystersteel is a 904L-family alloy that Rolex produces in house.
Checks on a 116710BLNR
- Bezel seam. The blue and black sections meet in one continuous ceramic piece. A glue line or a ridge at the junction points to a copy.
- Cyclops magnification. Genuine is 2.5x. Many copies sit near 2x.
- Dial text. Printing stays crisp under a loupe. The GMT-MASTER II line matches the blue of the 24-hour hand.
- Hand stack. Pull the crown to position 2. The hour hand jumps in one-hour steps and the 24-hour hand stays fixed.
- Case back. The 116710BLNR has a solid case back. The reference number is engraved between the lugs, and the bracelet must come off to read it.
- Movement. Caliber 3186 needs a case-back tool to open. A snap-off back or a display back is a sign of a copy.
Legal status in the United States
18 U.S.C. Section 2320 makes trafficking in counterfeit goods a federal crime. A first offense carries up to 10 years in prison and a $2 million fine for an individual, or $5 million for a corporation. Civil claims under the Lanham Act let the trademark owner recover profits, damages, and attorney fees. U.S. Customs and Border Protection can seize and destroy counterfeit watches at the border.
A "1:1" or "super clone" label describes appearance, not origin. A watch sold as a replica carries no Rolex warranty, no Rolex service records, and no resale value through authorized channels. Genuine 116710BLNR examples trade above the original list price on the secondary market, and authentication services exist for buyers who want a documented check.
