Rolex · GMT-Master II
Known in the trade as the Root Beer.
CHNR is chocolat-noir. Rolex codes its bezel colours in abbreviated French and appends them to the reference, which is why the same case turns up as several references: BLRO is bleu-rouge, the one everyone calls Pepsi, BLNR is bleu-noir, LN is lunette noire, LV lunette verte. Knowing the code is the difference between finding the watch and guessing at it.
The 126711CHNR has been in production since 2019.
The Rolex 126711CHNR runs the Cal. 3285, an automatic movement.
Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
