Rolex 116710LN was in production from 2007 to 2019, a run of 12 years, carrying the 3186 automatic caliber in a 40 mm case rated to 100 meters.
The first ceramic-bezel GMT: the Cerachrom era begins in black, with the maxi case and green 24-hour hand.
The full collector's file for this reference — variants, dial codes, and the authentication walk-through — is on the writing schedule; the specifications above are the permanent record.
GMT-Master fraud follows the family's own geology: on the long-lived vintage references every part has a documented era, and franken watches are assembled across them - gilt dials on late cases, swapped bezel inserts chasing ghost premiums, service dials priced as original. The rules: the serial dates the case and every visible part must belong to that era; bezel inserts swap in minutes and prove nothing; underline and error-dial claims carry the burden of proof; and on the ceramic references, counterfeit pressure is high enough that platform authentication is the sensible route. The Rolex serial lookup on this site covers every reference in this family.
